Product Overview

Description

product introduction

 Cold shrinkage technology is to use the excellent elasticity of silicone rubber and small permanent deformation, pre-expansion of silicone products, with support.When the support is removed during installation, the silicone product is rapidly contracted and tightened on the cable body.

Features: reliable insulation, resistance to electric leakage marks, resistance to electric corrosion, resistance to high and low temperature, resistance to harsh environment
