Full Cold Shrinkage Cable Accessories Series

Full Cold Shrinkage Cable Accessories Series

Product Feature

1.Reliable capability

It is made from imported-SiR (Silicon Rubber) with satisfying electric insulation, outstanding elasticity tracking resistance, corrosion resistance etc, as well as approved electric capability and long-term service-life. It can exert modest radial pressure upon the cable all the time to make the contact compact after installing.

Also it will expand or shrink simultaneously with the cable to avoid tip-and-run breakthrough caused by the working cable’s respiration. The stresscone and primary insulation are composite as one to ensure insulation reliable and performing safe by solving the problem of the stress concentration on the contour of the semiconductive layer.

2.Simple and convenient installation

By u , one with no special training can fix it without the assistant of fire, electricity. The process is simple and labor-saving.

It is adequate for aloftwork, fieldwork and works in the combustible environment in particular, such as , coal mine, oilfield and under-well. Thus greatly reduces the quality accidents caused by improper operation.

3.Excellent chemical capability

Feculence-resistance, alkali resistance, ageing resistance , perfect hydrophobic performance, superior heat and cold resistance are included. The proper working temperature ranges from -70℃ to +120℃. Therefore this product can be specially used in high-altitude, cold, humid, saline and foggy regions as well as heavy polluted areas.
