In power system, cable is widely used because of its convenient
construction and maintenance, high reliability of power supply. Due to
the simple and convenient field construction, the cold shrinkable tube
of the cold shrinkable cable head is elastic. As long as the inner core
nylon support strip is pulled out, it can be tightly attached to the
cable, without the use of heating tools, which overcomes the gap between
the heat shrinkable material and the cable body caused by the heat
expansion and cold shrinkage during the operation of the cable, so it is
more and more widely used.
1、 Basic process principle of making cold shrink cable head
By using the shrinkage of the cold shrink tube, the cold shrink tube is
completely close to the cable. At the same time, the semiconductor
self-adhesive tape is used to seal the port, so that it has good
insulation, waterproof and moisture-proof effect.
