wire jacket removing

Hello paritosh.pawan

Long ago we always practised with a curved bladed pocket-knife on scrap pieces of cable.

After a short time, with such practice, the job could be done without nicking of conductors, or damaged insulation.

How many of these do you need?

If there is less than 1,000, it's easier to get a person trained to do the job, because after an hour or two, almost every person becomes proficient.

Kind Regards....

thanks for responding. I have to use this for production. Machine is also available for that but it is too costly according to our quantity. will u pls send the picture of that curved knife & how it will work.

Thanks.

how many QTY it is ?if just one pCS.you should do it by yourself careful!

BR

no no it is for production, minimum 1000 pcs per month. Machine is also available but we cant use due to high cost. any manual method will u pls suggest

Thank u.

Since it is raw material going into a production sequence,why don't you order the wire without the jacket?

Hello djacob

The original Post says length of 2-3 metre, and the sheath is covering all that length of cable, except for a 10mm space in the centre of the length, where the insulated wires are exposed - evidently for some sort of connection.

The actual method of connection has not been explained.

Perhaps there is to be some sort of IDC (Insulation Displacement Connector) to be fitted there, that's how it presently appears to me, in the absence of further information.

Kind Regards....

ya absolutely correct, but that we can use when we have to strip at the end. but the problem is out of 2 m length we have to strip 10 cm.approx at the centre. pls re-think it and suggest some good idea.

Thank u.

I always kept a dull pocket knife for just this purpose. Score the jacket slightly around the cable at the end points and down the length between the end points and carefully use a sharp single edge razor blade to just start the tear down the length. Bending the cable sharply with the score line on the outside of the bend will make controlling the depth of the cut a lot easier without nicking a wire. Once you have penetrated the jacket very slightly, use a small screwdriver or awl that has been ground down to a rounded end to increase the tear until you can peel it away with your fingers. A little practice making the score lines just deep enough and stripping cable will almost be fun.

Yes I agree and slide a short peice of PVC pipe along the wires as you peel it back to give you support so the outer cover does not break.

Possibly you should think about simply using 4 separate wires and after assembly install a jacket over the prepared assembly. There are a lot of good looking products out there to chose from. Bellow is one of hundreds of suppliers for Heat Shrink, Looms, etc.

At the end of the day this may be more cost effective and depending on the application may produce a better quality job with no chances of accidentally damaging insulation of slicing someones fingers during the striping process.

These days I personally seem to heal a little slower and feel a lot more pain when something gets cut or smashed

It should not be too hard to make a simple jig that would do this having a groove to feed the wire in on a fixed bed and a knife blade capable of being set at an adjustable height from the bed, set over and parallel to the groove, in order to precisely score your outer insulation just deep enough to ALMOST go through the outer insulation so that the final thin part of the outer insulation could then be ripped open by hand, thus guaranteeing that the inner wires are never touched by the blade.

I use a short piece of pipe with a screw in it exposing a sharp point inside the pipe how much depends upon the insulation to be stripped.

Slip the tool over the wire then while holding the wire press the sharp point into the insulation as the pipe is pulled towards the wire end.

We used to use sewing seam rippers as they are blunt and only cut in the groove area. You can also make them from crochet hooks by sharpening the V area. No damaged conductors
