A stripper is a specialized tool that is used to strip wire insulation. You can use a regular knife for this, but it will take much more time to implement the plan. In addition, the risk of injury and damage to the cord should not be excluded. The stripper is used not only by professional electricians, but also by home craftsmen who prefer to fix wiring problems on their own. It should be noted that the described dialectical instrument has nothing in common with a crimper. The latter is used for crimping connectors.
If you plan to replace equipment in the switchboard, mount an outlet or extend an antenna or telephone cable, then the master will need to strip the ends of the cord for the subsequent change of insulation. For this, it becomes necessary to use a homemade or purchased stripper. Outwardly, the tool resembles ordinary pliers. It translates from English as a puller, which determines the scope of his activity. Previously, they used sharpened tools to strip the cable, but the final result left much to be desired.
With his own hands, a person could damage the veins or significantly cut the diameter of the cord, which ultimately made it ineffective. The quality of such wiring left much to be desired. With the advent of strippers on the domestic market, the risk of cable damage was minimized, and the process became less time-consuming. The functionality of the device is somewhat wider in comparison with construction knives. The latter do not allow you to make a smooth cut, especially for multi-core cables.
The current-carrying cable will be completely safe, as there is a convenient limiter in diameter and length.
We propose to discuss the principle of operation of a stripper using the example of removing insulation from wires with a cross section of 0.5-6 mm. Step-by-step instruction:
At home, such manipulations will take several seconds. After that, you should check that the cable was cleaned carefully. An even and bare tip may have minimal damage, which is then recommended to be opened with a transparent varnish.
In the process of stripping stranded or stranded wires, experts do not recommend using a knife. Thin outer copper conductors can be cut with ease in a single motion. This is fraught with the fact that in the process of removing the old insulation, the cores will break, the cable cross-section will be significantly reduced and it will no longer be able to perform its functions. This is especially true for large conductors.
Outwardly, this small machine looks like a pair of pliers, but in the inner part of the clamps there are several holes of different sizes with blades at the edges. This will allow you to work with material of any standard size. The best models have jacks in the case with a designated size, so removing the insulation from the wire will not cause any difficulties. The edges of the cable will be perfect.
After a short pressure, the mechanism will close the semicircular blades, thereby cutting the insulation material across. A review of popular models showed that some of them are equipped with mechanisms that independently determine and adjust to the cable cross-section. The limiter will not allow you to hook the adjacent section. You can also find a device that is equipped with legs with wedge-shaped cutouts that allow you to adjust to the cable diameter by means of an adjusting screw. What aspects should you look out for when selecting ticks?
|The form||The main problem when choosing a device, which often leads to mistakes, is the abundance of its forms, which mislead the buyer. The device can be made in the form of pliers with straight jaws, or the working surface will have a curved shape and end-type gripper. However, with their help it will be possible to get to the most inaccessible areas. Also, Russian-made goods may have special holes with blades located on the side.|
|Material||Depending on the type of fixture used, different raw materials may be involved. Tool steel is used for the manufacture of lever structures, in which manufacturers cover the handles with special insulating plastic. Also available with fiberglass and polyamide rubberized inserts. You can also find models equipped with metal blades and a plastic case. It is this option that is best purchased for home use.|
|Medium depth and section range||Each tool will operate within the manufacturer's specified cut range. The standard set is considered to be 0.2-0.5 mm or 6-10 mm. For micro-ranges, a 0.02-0.2 mm stripper is used. In most cases, there is also a special limiter. This is a plastic or metal element. It is used to fix the core in the designated position. Thus, a person will not be able to insert the wire deeper than possible. There is a possibility of adjustment. This is an extremely useful option for those who are used to performing monotonous manipulations every day.|
|Weight and size||The tool has a length of 14-22 cm and a width of 1-3 cm. The height reaches 6-13 cm. The weight of the product will be 50-450 g.|
Please note that not every stripper can be used with cords that are energized. Such manipulations should be carried out exclusively with automatic products with a special mark "electrically insulated".
According to buyers, such designations do not deserve special attention, as evidenced by numerous reviews on the network, however, this is a delusion. Not only the alphanumeric set is important, but also the color. An example is some American brands that mark the dimensional grid by dyeing the pens in different colors. Products from China (AliExpress) have standard designations. The numbers are the working range of the supported section. Opposite each blade is a cross-sectional designation that refers directly to the wire.
Designations can be either in square millimeters or in AWG format, which has its own calibration. It is recommended to use the mechanism strictly for its intended purpose, otherwise the risk of damage to the wire increases. Popular models may have the designation 1000V, which indicates that the buyer is facing a structure equipped with electrical insulation. For this, a special type of material is used. Dots of red, blue and yellow can be found on the product, the configuration of which allows crimping the terminals. This indicates the correspondence of the cuffs of the tips, which can be processed using the selected device, where the section will be:
Before you buy a stripper, you should decide on the area of its use. The cost of the product, experience with similar equipment and the designated scope of work are also taken into account. You can buy an accessory at any building or online store. There you can also see how much a similar tool costs. However, it is recommended to give preference to kits that will support the maximum range of the working section. If a person does not plan to independently figure out how to set it up, then special attention should be paid to multifunctional models. Thus, the work will proceed at an accelerated rate.
If a person plans to do this on a regular basis, then the scope of activity will be extensive. In this case, the device must be equipped with a screw that allows micro-adjustment of the cross-section. The device can be adjusted manually, without assistance. If you plan to use the gadget exclusively at home, then a range of 0.2-4 mm2 is considered sufficient. Also, it will not be superfluous to pay attention to the presence of additional knives in the set, which will allow you to replace yourself, and not buy a new tool.
If experience with such devices is not enough, then automatic and semi-automatic models should be preferred. This is the only way to minimize the risk of damage.
Such a device belongs to the category of the simplest. It is a pliers that are equipped with small grooves with sharp edges. The removal of the old layer of insulation will be carried out due to the ongoing circular movements. The cutting element will pass through the edge as the handle is squeezed. A spring is provided in order not to spread the pliers manually. The handle lock will protect children from accidental contact with cutting elements. The weight and dimensions of strippers from the world's best manufacturers will be insignificant.
The rating opens the model for an advanced user. The function of protecting conductors of a certain range is provided. The device can be used for crimping terminals and cutting wires. Used for crimping coaxial connectors. Outwardly, the device differs from similar devices, which makes it so popular. It is characterized by the presence of a handle of normal volume. However, there is no return spring. If a crimper is not available, pliers or a stripper tip can be used. As a last resort, multitool undershooting will come to the rescue.
The average price of a novelty is 1300 rubles.

The stripper is a popular type of tool that is used in the process of electrical work. Used to remove old insulating material from wires of any cross-section. There are several types of devices:
When connecting household tools, appliances, cables, telephone lines and other electrically conductive paths, preliminary processing of conductors is required.Such manipulations should be performed in the best possible way. Damage should be avoided. To do this, you need a special tool that is used to strip the insulation. We are talking about strippers that will remove old material accurately, without damage and in a matter of seconds.
In order for the work to be done efficiently, it is necessary to choose the right tool, which may not belong to the category of universal (multifunctional). First of all, you need to pay attention to the type of cable used and its diameter. Safety comes first. It will not be superfluous to pay attention to the models, the handles of which have a dielectric coating. This will eliminate the possibility of electric shock while working with energized wires.
