Silicone Rubber Coating Fiberglass Sleeving
(SRG-1) |
| |
The kind of tubing produced with the process of thermal and vulca nization is the non-alkali fiberglass braided silicone rubber tubing. This tubing possesses good pualities of dielectric high temperature resistance and cold resistance and can be used as wiring insulator for "H" grade electrical machinery, special bulbs,electrical rich cookers as well as other household appliance and their protection device. |

|
|
Color scheme： |
| |
The standard color is white.(red, blue, black and yellow, are by special order.) |
| |
|
|
Type： |
| |
Two types are classified according to the degrees of insulation with stand voltage. |
| |
 |
SRG-1：For high voltage circuits or "H" class insulation.(7KV) |
|
SRG-1(4KV)：For low voltage circuits or "H" class general insulation |
| |
|
| |
|
|
Packing： |
| |
The general length is 100M/RL.(the length can be negotiated) |
