Silicone heating 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 antifreeze heating wires for pipe and tank, etc.
There are three main models PVC wires:
A, SH-SR-20
B, SH-BSR-20
C, SH-2SR-20
D,SH-SR2-20
however, their technical parameter is almost same.
Silicone rubber heating cable comprises alloy heating wire, silicone rubber and high temperature insulation cloth. This cable heat quickly, and has even temperature, hight thermal frequency, fine ductile, etc., features.
Resistance wire alloy spirally applied around a glass "Aramid" fiber core, or single (stranded) alloy wires as core wire, coated with silicon rubber/PVC insulation as jacket.
