highly heat- resistant silicone- sheathed copper wire

 highly heat- resistant silicone- sheathed copper wire :

Due to the good combination of properties such as good electrical insulating ability, flexibility and excellent heat conductivity, the silicone rubber heating wires which SENPHUS manufactures have been widely used in electric cushion, electric cloth, animal pet, jade mattress, electric shoes, electric massage armchair, car windows, electric towel rack, heat-preservation-type rice cooker, etc. products as heating wires, and in air condition, refrigerator, cooler, etc. to prevent the formation of condensation on surfaces. Besides, the wires could be used as the anti-freeze heating wires for pipe and tank, etc.

There are three main models Silicone wires:        

A, SH-SR-20

B, SH-BSR-20

C, SH-2SR-20

however, their technical parameter is almost same.

A, common silicone rubber heating wire:

SH-SR-20

Rated temperature:150°C-200°C -            

Rated voltage:300V-600V                   

Conductor:single conductor alloy or resistance wires twist into a spiral on fiberglass

insulation: silicone rubber 

B, braided silicone rubber heating wire:SH-BSR-20

rated temperature:200°C  

rated voltage:300V                  

single conductor alloy or resistance wires twist into a spiral on fiberglass

insulation: silicone rubber

reinforced jacket: braided fiberglass layer

Except the O.D. of finished product, other parameters are same or similar to those of SH-SR-20.

C, SH-2SR-20

Rated temperature:150°C-200°C                    

Rated volt:300V- 600V                 

First layer heating conductor: resistance wires twist into a spiral on fiberglass    

Second layer heating conductor:alloy wires twist into a spiral on the silicone rubber heating wire

insulation:silicone rubber

Similar to thoset of SH-SR-20.

D, two core silicone rubber heating wires:

rated temperature:150°C-200°C  

rated voltage:300V-600V         

Twin Conductor: single conductor alloy or resistance wires twist into a spiral on fiberglass

insulation:silicone rubber

the O.D. of this kind of wires is about 4mm. Other parameters are similar to thoset of SH-SR-20.
