tools and appliances for working with electrical cables from Aliexpress
Carrying out local work with electricity in the home or in dacha conditions, is quite accessible to almost any handy man. For the organization and convenience of such works, you need a certain arsenal of tools and devices to get everything right and neat. In this selection I gathered exactly those gizmos that will be useful to any home handyman. The main thing is to remember to disconnect the power before doing anything.
Cable stripping tool
First of all it is necessary to prepare a cable by cutting a piece of it to the right length or, for example, to trim separate old or damaged wires coming out of the braid to the same length. You can do it with special cable cutters with rounded edges adapted specifically for cutting cable. There are several options on the product page for working with different cable diameters from 25 to 70 kV.mm
Pliers for low current
If you work with thin low-current wires, twisted pair, cutting feet of electronic components, etc., it is more appropriate and convenient to use small special pliers with a bent at an angle of 45 degrees working parts with sharp cutting edges for trimming purposes. The tool is equipped with a return spring and insulated handles.
Pliers for cable stripping
Perhaps one of the most popular and common tools for working with cable is the special insulation stripper. Their popularity is due to their versatility, i.e.к. the pliers can remove the braid from the cable in a fairly wide range of its cross-section from 0.5 to 6 kV.mm. Besides, this tool can also cut the wire and crimp the terminal, if it is used for connection. Pliers are equipped with stripping length limiter. When purchasing, I advise you to choose the D3 version on the product page as it is more reliable.
If you want to carry around large wire strippers with you, you can use a small manual stripper to do the stripping. This tool is suitable for work not only with electrical, but also with coaxial cable or twisted pair, i.e.к. it is possible to set the diameter of cable to be worked with the tool. The use is simple, the tool is placed on the wire and rotated around it to cut and remove the insulation to the desired length.
Pliers and pliers for working with cable
In addition to special tools for cutting and stripping insulation, it is logical to have in the “tool kit” and more versatile, such as pliers or cutters, equipped with elements specifically designed for electrical. These tools will not only allow you to remove the braid or cut the cable, but also to trim the cable channel, remove fasteners and perform other related operations. There are several good options on the product page for different sizes. The tool is equipped with well-insulated handles.
Wire stranding tool
After the wires are cut and stripped of their insulation, they need to be connected. There are many ways to connect, and twisting wires is one of them. Hand-twisting, especially if the wires have a fairly large cross-section, is quite problematic. However, there is a special tool that can both trim the insulation and neatly make a reliable strand of multiple strands. The tool comes in two versions: for making twists by hand (with protruding handles) or using an electric screwdriver. Two to five wires can be stranded at a time. Although it is said that the tool can peel the insulation, I would recommend to do it beforehand and strand already clean wires.
Multi-wire crimping tool
The correct wiring should be done with a stranded wire, and it is better to connect such a cable by soldering or with the help of terminals. When using terminals, screw or clamp, not to damage thin wire strands, it is highly desirable to put NSHVI (insulated bush-type lugs) on the stripped ends of the wire. For their fixation just such pliers are required, they evenly squeeze from four (or six) sides of the tip, so that it is well fixed and a large contact area is obtained. On the page of the goods not only pliers themselves, but also sets with tips of different diameters and lengths. I recommend buying a version with six crimping cams, I myself use it when installing lighting fixtures, electrical plugs for devices, etc.
Pliers for special terminals
It often happens that when repairing some electric device one needs to replace a broken or burnt-out terminal of a certain shape at the end of the electric wire. The variants of such terminals are quite diverse, including the thickness of cable to which they are installed and the way of fixation on it. For this, you can use universal crimping pliers, which are designed just for crimping terminals. The tool has replaceable dies, that can be changed for the necessary type of terminals. On the product page you can choose from a variety of kits with different numbers of interchangeable dies.
Soldering set for electrical wiring work
Ligatures and terminals are good, of course, but often you just can’t do without soldering the connection of electric wire. That’s why the soldering iron is an indispensable thing for every home handyman. For residential use the all-in-one kit is a good choice. The set includes all components necessary for comfortable soldering: soldering iron with adjustable temperature of the tip, solder, stand, interchangeable tips, tweezers and even a small multimeter. The whole set comes in a zippered case. A soldering iron with a 60W soldering iron is powerful enough for every household task.
Heat shrink tubing
All electrical connections must be insulated to prevent short circuits. For this we can use duct tape (blue 🙂 or use heat shrinkable tubes, that when heated shrink significantly reduce in diameter and get thicker. It comes with tubes of different diameters and a length of 45mm. Simply put on the junction of the electrical wires and heat it with a soldering iron or a heat gun.
I hope that the tools and appliances collected in the selection for working with electrical cable were interesting, and maybe even useful 🙂 Other popular product picks and reviews of interesting gizmos, you can find just below in the author’s profile. Thank you for your consideration. Happy and profitable shopping!

Power tools are a must for any electrician’s equipment. After all, to perform such conventional electrical work as stripping wires, connecting fuses and outlets, installation of junction boxes without electrical tools will not work, even if you know all the theoretical foundations of this issue perfectly.
Stripping is performed on thousands of wires every day, usually with a professional tool. Often, however, many professionals in a hurry do it with a sharp blade. There are several consequences of such stripping for electrical connections: cores and insulation are damaged or the specified stripping length is not met, making the connection inadequate.
These errors are prevented by professional tools for stripping and sheathing. The procedures can be standardized, and the quality of the connections remains stable. One such tool is such a device as a stripper. This tool is suitable for professional use and characterized by an extremely long service life.
In the recent past, stripping wire insulation was done exclusively with a hand knife. But those days are over. today there is a wire stripping tool called a “stripper”. The model WS-04B from KVT is rightfully considered one of the most universal, convenient and successful. Let’s try to understand the construction of this interesting tool and how it works in detail.
By the way friends on the site I recently published an article about the review of the knife STOK with a heel for cutting cables from the outer insulation. Please come in and take a look.
How to Use a Wire Stripper?
Pliers for stripping differ both in principle and design. There are manual, semi-automatic, automatic strippers. What they all have in common is that they all work by cutting the insulation and stripping it from a wire to a specific length.
Handheld pullers have the simplest mechanism of operation. In appearance, mechanical stripper looks like a pair of pliers, but the jaws additionally have slots with blades for different cross-sections of current-carrying conductors. This type of tool is suitable for stripping wire insulation with cross section not exceeding 6 mm.square., and for crimping lugs (some models allow this). Working with a handheld stripper is not difficult, just insert the wire in the socket, press the handles (grip) and make a circular motion, which results in stripping the insulating sheath.
Semi-automatic models are even easier to use. The mechanism is more advanced, so there is no need to rotate the stripper around the wire by yourself. Simply clamp the wire in the correct slot and press the handle. Also many models of semi-automatic strippers allow cutting wires and crimping lugs.
Automatic stripper is a professional tool for stripping wire. Its difference from semi-automatic stripper is independent determination of wire cross-section, thanks to which stripping process is reduced to just putting core into the socket and pressing the handle. Automatic strippers are the most expensive, but they can also simultaneously remove protective sleeving from multiple wires, strip insulation from the middle of the wire, peel off the jacket of flat conductors, and much more.
Varieties of wire strippers for crimping stranded wires
In the above article there is a lot of information about the tool used for crimping. But for the quality of the connection it is equally important to choose the right tip. There are several kinds of them, too. Let us focus on the products for stranded wires.
The tool for stripping wires: a variety of devices
Characteristics, sphere of application. Varieties of devices. Types of strippers. Popular models from well-known brands.
Copper tips. They look like a copper tube, flattened on one side, in which there is a hole for the bolt. These tips are divided into uncoated (ТМ) and tinned (ТМL) elements. The latter are used when it is necessary to make connection with high anticorrosive properties. These tips can be crimped by any type of pliers, whose dies correspond to the cross sectional area.
Copper with a test hole. This version is not crimpable, so solder is used for the connection. Information provided for general information. Externally, the lugs are similar to the previous types, differing only in the presence of a hole through which you can see the position of conductors.
Insulated lugs are suitable for stranded wires, uninsulated for solid single-wire wires
Aluminum. Aluminium wire is crimped with lugs made of the same material. Externally, they are absolutely similar to copper wires, marked МА.
Important! Before crimping, aluminum conductors need to be treated with quartz-vaseline paste. It prevents the formation of an oxide film.
Press jaws for crimping lugs of this type can be used both hydraulically and manually.
Ferrules. They are used to make non-detachable connections. They are marked with the abbreviation NSHVI. male rod insulated lug. Stripped wires are fed into the ferrule and crimped with a crimping tool.
Copper lugs with test holes are not subject to crimping
Crimping lugs: ring, hook, fork
To connect to terminals, it is necessary to use lugs that provide the most reliable connection. The main prerequisite is that they must be suitable for this type of terminal block. Today there are three main types of crimp terminals:
- Circular. Their purpose is to attach to screw terminals. Providing a large contact area is one of the advantages of this type of lugs. This option is used for temporary and permanent connections in networks with low voltage.
- Hook type ferrules. They create a contact surface that is one-quarter smaller than the ring type. It is not necessary to completely remove the retaining screw to crimp the electric cable with this type of lug and connect it to the terminal. Such tips are often used for temporary connections or in situations where it is impossible to unscrew the screw for some reason.
- Fork lugs. These tips have a contact surface that is 50% smaller than that of ring tips. For this reason, they are often used for temporary connection, when a constant change of terminals is needed.
There are also other types of tips, but they are specific and are used rather rarely, mainly by professional electricians when mounting complex circuits.
With press pliers one can press various types of lugs: ring, forked, stabbed
Domestically produced tools: pincers for crimping lugs KVT
Among domestically made tools the following ones deserve attention: crimping pliers for wire lugs by KVT. The main company is located in. Kaluga. Kits CTF, which includes dies for pressing of insulated and non-insulated lugs, and sets CTB, which includes numbered dies, are especially popular.
The STB set consists of the following items:
The pliers feature a quick-change mechanism for replacing the dies. The material used for the tool is stainless steel. Press construction includes a release lever. If the wrong die size is selected, the pressing process may not end, causing the handles to lock in an intermediate position. In these cases, it is possible to return to the starting point with the lever.
It is worth noting that the handles of the pliers are elongated, so that they can be crimped with both hands. Five dies make it possible to select the right option for a certain type of handpiece.
The KVT wire lug crimping pliers are a much sought after tool
The CTF set also has 5 matrices. Cable lug press pliers have no quick-release device, so a hexagonal wrench is necessary. The process of replacing the die takes quite a long time, sometimes even longer than the crimping itself. The CTF kit (in contrast to CTB) includes two additional die screws in case the used one is lost or damaged.
Important! When inserting the dies, in order not to make a mistake, it is necessary to pay attention to the size of the slit: the big one goes towards the handles, the smaller one. in the direction of the pincer head.
Hydraulic wire lug crimping pliers
In the course of electrical installation work hydraulic mechanisms are actively used. The main components of such pincer presses are:
The hydraulic wire lug crimping pliers have an open or closed head. With a closed version, first the stopper is opened, the die is pulled out, the wire with the sleeve is laid, closed, and only after that is crimped. With an open-head design there is no need for any preparatory work, making crimping considerably faster.
Each model is designed for a certain size range of wire cross section. The maximum dimension is 400 mm. In the home such wires are not used, but it is convenient to work with a tip for crimping 6 mm with hydraulic pliers. But there is a risk of over-pressing.
Hydraulic hand press for crimping cable lugs can have a closed and open head
Useful tip! For work with soft wire is better to get a hydraulic press with a limiter. This prevents overloading the tool.
To clearly imagine the consequences of a crimping hydro-press, it is worth to understand the mechanism of its action.
Through the rocking action of the knob, the plunger (pump piston) moves reciprocally and a certain pressure is created so that the oil flows into the cylinder. The oil moves the cylinder, which, in its turn, creates pressure in the die, and it acts with the necessary force on a sleeve.
A tool for crimping Internet wire lugs
Stable operation of any cable system consists of several indicators. First of all, it is the quality of the material of the cable itself. The next is a professional level of specialists who carry out installation. Technical condition of equipment is important. Completely unreasonable among the latter is the quality of connections.
Many models of crimping pliers for Internet cables are equipped with special cutters
Contacts are quite often the cause of unstable or weak signals. Avoid problems in the work of the cable system associated with unprofessionally made connections, you can only use a special tool. crimping pliers, which are called “crimper.
Performance of any cable connection always begins with stripping of insulation from wire ends. For this purpose there is also a separate type of tool called “stripper. It removes the top layer, there is no danger of damaging the core. Alternatively, you can buy a crimper, which has elements that allow for stripping. This is a hole with a blade on one side. Inserting the wire and turning it once, you can get the desired result.
Crimps for crimping lugs and stripping wires are actively used by specialists when installing structured cabling systems.
Modern manufacturers offer various modifications of crimping pliers, which may differ from each other both by design and functionality. Thus, depending on the main purpose distinguish two types of such tools:
Crimping pliers for stripping conductors
- hand crimper. rather simple in design, but effective device, with the help of which crimping of cable lugs and sleeves of different sizes, as well as mounting of contact connectors and terminals can be performed (some models are equipped with special blades installed in the place of handles fastening; availability of such blades in pliers design allows using them also for cutting electric cables and wires with their help);
- electric pliers. a tool designed for mainly professional use (such universal pliers can be used not only for crimping cable lugs and connecting sleeves of insulated and non-insulated type, but also for stripping insulation from electrical conductors);
- crimps. tools with the help of which one can mount connectors and crimp lugs for wires, as well as perform crimping of twisted pair (such pliers are equipped with two long handles, of which both can be movable or one, a solid working part consisting of two working jaws, between which there are sockets for cables and wires of a certain diameter; some models of crimps may also have blades, used for cutting electric cables and wires).
Crimper for crimping lugs with a set of interchangeable dies
Hand-operated hydraulic press and electrically operated equipment can also be used for crimping.
Using a crimping tool for crimping lugs and crimping sleeves with these flanges allows for better crimping of stranded conductors.
Depending on the type of contact elements the pliers are designed to work with, these tools can belong to one of the following types
- press jaws designed for crimping insulated type sleeves;
- Crimping tool for crimping un-insulated connection tubes.
Tooling for standard, non-insulated terminals
Crimping tool for insulated terminals with different jaw profile for accurate crimping of the termination without damaging the PVC-tube
The first type of crimping pliers have three oval-shaped working sockets, each marked in a different color. yellow, red, and blue. The color of the insulated pressing sleeves for which these crimping pliers are used is the same, so it is no problem to select a suitable tooling socket for them. In order to form a quality and reliable contact between the tube and the electrical conductor placed in it, the following nuance should be taken into account when using such crimping pliers: the edge of the joint during crimping should be located in the middle of the upper profile of the crimping pliers’ jaws.
The punch of crimping pliers designed to work with uninsulated thermowells is a metal bar, which should be located on the separation junction during the crimping process. Thus, the crimping of the connecting tube using this type of tool is carried out in its central part.
The construction and shape of the tool affects its application. The variety of models that manufacturers make allows specialized companies to perform any task.
Pliers for terminating stranded wires and lugs with thin walls
This tool is used for pressing thin-walled electrical cables. They can even have a sectional area of 0.25 mm². These wires can be connected to crimp-type lugs.
Not stripping many cores at the end of the cable when using high-quality crimping sleeves. This makes it quick and easy to make connections to terminals in various devices.
Press jaws for wire with multiple conductors and lugs with thick walls
This tool is larger in size than the clamping pliers described above. Each model is manufactured with a matrix for specific tip sizes. For example, KVT company produces crimper PC-16, which has 5 working zones. After using the pliers, a special mark is imprinted on the sleeve.
Press jaws may have a “Y” in the name. It indicates that the crimper is designed with a ratchet mechanism that is located in the handle of the tool.
Another way to strip wires is to use wire cutters. This method of stripping wires requires experience. The wire can be easily cut with the wire cutters, or even bitten off.
No great force should be exerted on the pliers, but it is enough to press the insulation in the desired location by twisting the pliers around the insulation and pulling it off the end of the wire. This method is difficult to strip stranded wire. The wire cutters squeeze the insulation through the stranded wire and can easily damage thinner wires.
When stripping wire, use wire cutters with the back of the tool pointed in the direction of the stripping. The internal side with the sharpened side is worse for stripping the insulation, because the bevel for sharpening does not allow the pieces to lean well into the insulation.
