Silicone Rubber Coating Fiberglass Sleeving

 

 

 

    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

The standard color is White. ( But Red、Blue, and Black are available by special order. )

 

  Type

Two types are classified according to the degrees of insulation withstand voltage.

SRG-1 ( 7Kv ) :  For use high voltage circuits or H class general insulation.

SRG-1 ( 4Kv ) :  For use low voltage circuits or H class general insulation.

 

  Length

Total length 1000mm ±20mm. ( Continuous length may be negotiated )
