The use of cross-linking polyethylene was increased, especially for the
medium & high voltage electrical cables instead of paper and oil insulating
materials. The radiated low density polyethylene is the best technique in the
process of cross-link
ing instead of chemical method.
The purpose of this study is to find the relation between mechanical
properties of polyethylene samples and the dose rate of irradiation to cross –
link the polyethylene materials and to get the best properties.
This paper illustrates also the important results, that we have obtained in
this study.

The majority of known polymer materials are electrically insulating.
But there are some of polymers are intrinsically conducting in
nature, However, it is lacking in process ability, and the scope for
manipulation of electrical and mechanical prop
erties is limited. The
method which used to solve this problem is an addition of a
conductive metal filament into a polymer filament yarn. Which can
be directly integrated into a textile, or can be knitted. So we made
a device able to produce this kind of conductive yarns which
depends on melt spinning technique but with the elimination of
necessary pressure for extrusion. And we were able to produce
samples of copper filament coated with polymeric material (low
density polyethylene).
