During installation wiring one of the most important milestones is strippable.Any aluminum wire, copper coated with enamel or plastic insulation, in each case must be observed when cleaning technology.If you ignore the advice and tips on how to clean the wire, the technical characteristics of the electrical system will be made low.Consider some techniques for stripping a variety of coated wire.
solid and stranded wires
wires are of two types:
Under the single-core wire is meant, in which the cross section is formed one living or wiring.As for multi-core, the cross section of the wire is formed by several thin wires, which in some cases are intertwined.To multifilamentary wire was resilient and elastic thread is added to the structure that resembles nylon.G
correct direction of the knife blade
When removing the knife can not cut the insulation around the wire blade perpendicular position - can be formed notching copper wires.As a result, a slight bend the wire easily and quickly breaks down in this place, especially if you come to strip the wire thickness of 0.6-0.8 mm.After a few bends the wire completely breaks down.When wire stripper knife blade should be almost coplanar with the axis of the wire.The pre-insulation is cut along the vein.Cut along the insulation led away and just cut off.
use side cutters
Stripping side cutters
a tool like cutter, is often used incorrectly.The tool picks up as it is necessary, do not pay attention to the direction of the cutting edges.When used improperly, side cutters will have to make great efforts.Also in this case, there is a great risk to break off the wire with insulation.
It is important that the cutting edges are directed in the direction opposite the movement of the tool.In this embodiment, the blade will sink into isolation, even with little effort.As a result, the insulation tube is removed from the surface of the conductor without damaging it.
Scraping with a soldering iron
If you have a soldering iron can be quickly removed by thermal insulation.To do this, heat the soldering tip and spend a little on the plastic insulation.After heating and melted plastic comes off.This method does not violate the conductor.If you need to clean up the large number of wires with the coil, it is recommended to use a special tool.For example, suitable to the special burns wood, which was formerly known as "pattern."
reflow method is most effective if your wiring is old.After a long life of the plastic coil on the wire becomes hard and brittle.Especially, if the wire from the junction box looks at two or three centimeters or wire cutters or a knife will not be able to cope with it.And if you use a lighter or a soldering iron crawl, then you clean the wire out.
If enameled wire
If the conductor has a thickness of 0.2 mm, then the best option is a mechanical method of removal of insulation.To do this, use a knife or sandpaper, which is scraped off the insulation.
- cable processing, which has a thin insulation can be used fine sandpaper section.Fold it in half sandpaper inside.The cable is then rewound to the bent sheet sandpaper and lightly pressing your fingers, pull the wire.This procedure should continue as long as the enamel is not cleaned.
- If you use the knife portion of the cable must be put on a firm footing.Then, it is necessary to turn around the circle until until enamel scraped from the surface of the conductor.
If even thinner conductor and has a diameter of less than 0.2 millimeter, the mechanical method is not effective.This is due to the fact that the resulting enamel does not clear, and the wire may break.In this case, you can learn a thermochemical method using a soldering iron and vinyl chloride insulation.To begin heat the soldering iron, when put on the table, vinyl chloride, and on top of the wire, and it will lead soldering.Under the influence of heat generated chlorine, which cleanse the lead from the enamel.
In most cases, these wires are used for radio communication, and that it is wound on the coil inductance.He also has a name - litsendrat.In his mind, he is characterized by a large number of thin wires which are suites and one conductor is covered with the enamel.
Removing PTFE insulation
Under Teflon meant a polymer which is produced by a chemical method.It has a number of positive characteristics, for example, it does not get wet by water and is highly resistant to organic substances.Its technical characteristics allow it to withstand temperatures up to 300 ° C!As the insulation is ideal, but the main disadvantage of a high price.In this regard, it is used in special cases.In everyday life, it is applicable in many radio amateurs, because after soldering it has aesthetic appearance, takes up little space and are not melted.
very same material is shaped like a thin narrow strip.It, in turn, is tightly wound on the stranded core wire.Clean such isolation is possible only with a knife.Teflon scraped to the desired length.Once the wire is exposed, the insulation is removed to the desired length, and the remaining Teflon cut.
All of the above methods of hand.They require more time and attention, not to mention the experience when it comes to multi-core cables with a small cross section.If you are working in this area, and you must be regularly cleaned from wire insulation, it is best to partially automate the process.To do this, they have been specially designed clamps or even their name - a stripper.
With insulation stripper removes one-touch palm.Consider how to strip wire using a stripper model WS-04.
Specifications stripper WS-04:
- You can take a bite wire insulation and Ø0,5-2,7 mm cross-section of 0.2 to 6.0 mm2, without pre-setting.
- When setting microscopic screws removed insulation can be thin wires ranging in size from 0.25 to 0.5 mm.
- Stripper allows pressed onto the connector wires without insulation, insulated wire or road under the double clip 0,8-2,7 mm.
in appearance resembles a stripper pliers, at the end of which there is a cam lever.The upper jaws are mobile and permanently installed lower.To clamp a pair of wires is left, and the right to remove and trim insulation.The first intelligence handles, left fist grips the wire and the right cuts its sharp edge in isolation.With the constant reduction of leverage insulation gradually removed from the wire.The process of stripping wire stripper takes a few seconds.
Stripping stranded cable
process consistent performance stripper model WS-04 with solid, stranded and two-core cable:
- wire is put between the cutting blades, which are located on the inner side of the handle.Then, they should be reduced.The result is a cut end of the wire without deformation.For comparison, the cut end of the wire cutters always flattened and slightly sharpened.
- In the next step one end of the wire is put between the mobile and the fixed jaw.After compression handles insulation removed.In this work on the conductor does not appear to be any nadsechek.
- to adjust the exact length of the removable insulation can use the blue stop moving.
- on two-wire insulation stripper is removed with two taps.
- the first approach of vinyl chloride tube is removed.
- the second stage at the same time removed the insulation from both wires.
In addition, you can use the stripper and stripping telephone cable before pressing with a RJ-11 connector.If a screw connection, the only one movement remove insulation from the wires.
also a stripper can be used to remove the shielded wires.First of all, it should be noted that it is quite a difficult task, it is especially complicated if the conductor is thin.So the first thing is removed insulation with shielding.To expose the central wire spliced braid using a needle or spike.It remains to make one move and wire stripper released from isolation.Clean shielded wire manually laborious work, especially if you have to hand the knife.Knife is very easy to damage the wires!
So, as you can see a stripper pretty versatile tool that cleans the various wires from the insulation.
Strip the insulation on the coaxial cable you can own hands.Although the equipment for this purpose inexpensive and available, we will tell you how to do the job cutters and knife.As a rule, this cable is used to connect the satellite TV for standard connectors F.
Types coaxial cable
Step by step instructions how to clean the wire coaxial:
- cable must be taken in the direction of your body.
- Take stationery knife and press firmly onto the cable at a right angle from the end of the cable at a distance of 2.5 cm. You can not press the blade end otherwise it will break off and can rebound in his eyes.
- At this stage it is necessary to penetrate the outer sheath, braid, a foil layer and a dielectric foam.In most cases it is white in color.It is surrounded by such layers and lived.During the immersion of the blade into the cable you feel some resistance.Once the blade has gone to half of wire is necessary to put pressure on him less.It is important not to damage the central conductor!
- Then follows a walk around the cable.At the same time, be careful not to leave notches on the conductor.
- Now for the cut edge insulation pull and twist.By doing so, you can remove the severed end of the insulation.If
- from the sheath wires sticking out, then they cut the wire cutters so they do not go beyond the edge of the shell.It is important to examine the wiring for serif.If there are, then the above procedure should be repeated.
- foam dielectric may partly remain on the main vein.You can simply remove the nail.
- To connect the cable to the connector F, first remove a small portion of the upper shell.
- to this place from the previous cut, measure eight millimeters.Make an incision in the upper shell.As in the previous case, the incision is made perpendicular to the wire.Be careful not to hook the braid.In some embodiments of the connector to remove the sheath F is no need, and in the other, on the contrary, it must be removed.
- If you are not sure whether the need to braid your case, leave it temporarily.This braid is around insulating foam.Her postings have a thickness less than a human hair, so all the work should be carried out carefully.Just after the incision is now necessary to make the tip of the blade across the wire.
- 're shooting eight millimeters sheath so that the conductor remained on the dielectric foam, wrapped in a coil.
- braid wrapped over the outer sheath.For example, the dielectric is laid bare.At this point, pay attention to the requirement F-connector: what kind of end of the wire has to be in your case.
- between the braid and center conductor must be free of all possible wiring.Against the background of the white dielectric it will be clearly seen.
- At the end of the cable is placed F-connector.
- dielectric must be located at the bottom of the connector after landing on it.It is unacceptable that he looked or did not get to the bottom connector.
Now F-connector ready for use.
knives cable stripping
should also be said about the special knives, which are directly used for stripping cable.For example, the most popular - a knife with a hook.In operation, it is much more convenient stationery.Moreover, due to the thick blade it is possible to work more confidently and boldly.Cut the wire insulation it will be difficult, but cutting the cable along: this is what you need.This hook is good bites into the cable sheath, so that did not jump out of it.However, this tool does not have all the advantages, because it can not provide good stripping.
known other special knife.
In this paper it is very simple.To begin with the thumb pulls a special bracket.It was under it, you will be put wire.This place looks a little out of the pen knife, rotating around its axis.After laying the cable clamp presses it to the knife.You make two or three turns around the wire until a notch.Now, without taking out the wire pull the tool with a force in the direction of the end.The knife will turn and cut along the shell.In the end there will simply remove the severed part and continue.
The only drawback of this device is that it is necessary to adjust the wheel directly below the depth of a particular type of wire.To customize, you can use a piece of wire.
also a knife is not very successfully copes with the removal of the insulation.This is due to the fact that the device can flatten thick cable by careless actions.
So, we have considered the most common methods of removing the insulation from the wire.Perhaps one of the methods described above will be useful to you.Successful you work!
