Silicone Rubber Insulation Wire (SIF-THT/SIE-THT)

SIF-THT and SIE-THT silicone rubber insulation wire has copper brass or tin coated conductor wire. Bare copper wire can transmit the signal most stably and tin coated copper wire has superior anti oxidization ability. The SIF-THT type wire's conductor is a wire harness but the SIE-THT type wire's is a wire with certain diameter. This silicone rubber insulation wire has the rated voltage of 300V or 500V. Thanks to the application of silicone rubber insulator, our insulation wire can work normally with a wide range of ambient temperature from -60℃ to 250℃. The insulation resistance of this electrical wire can reach 30.5 MΩ per kilometer.
