Glass Sleeving slicon Rubber Sleeving
Product Introduction
Description :
The kind of tubing produced with the process of thermal and vulcanization is the non-alkali fiberglass braided silicone rubber tubing. This tubing possesses good qualities of dielectric high temperature resistance and cold resistance and can be use as wiring insulator for H grade electrical machinery, special bulbs, electrical rice cookers as well as other household appliance and their protection device.
Color scheme.
The standard color is white. But red, yellow, green, blue, and black are available by special order.
Type.
Two types are classified according to the degrees of insulation withstand voltage.
SRG-1: For use high voltage circuits.
FSG-2: For use low voltage circuits or “H” class general insulation.
Length.
Total length 1000mm ±20mm. (Continuous length may be negotiated).
