Silicone Rubber Insulated Heating Cable
Silicone rubber insulated heating cables are often used because of their electrical insulating ability, flexibility and excellent heat conductivity properties. Senphus silicone wires are wide installed in electric cushions, electric blankets, massage chairs as well as automotive and home appliance applications. They are also used as heating wires to prevent pipes from freezing.
There are three main models silicone wires:
A, SH-SR-20
B, SH-BSR-20
C, SH-2SR-20
