Factory wholesale Semi-Conductive Nylon Fabric For Cable - Semi-conductive Water Blocking Tape – ONE WORLD Detail:

Introduction

Semi-conductive water blocking tape which is compounded of non-woven fabric, semi-conductive material and super-absorbent material can be divided into single-sided semi-conductive water blocking tape and double-sided semi-conductive water blocking tape. Semi-conductive water blocking tape has features of strong hygroscopicity, large expansion rate and fast expansion rate. Our product also has features of low resistance, semi-conductive characteristics, weakening the electric field strength, high mechanical strength, non-corrosive, easy cable wrapping and longitudinal wrapping processing, good heat resistance, high instant temperature resistance and other characteristics so that the cable can maintain stable performance at instant high temperature.
Semi-conductive water blocking tape is used for blocking water between various structural components of waterproof MV, HV, EHV power cables, and plays a role in blocking water and weakening the electric field strength.
