橡套电缆 Silicon Cables

 

Silicone rubber has excellent electrical properties&high thermal resistance.It allows conductor temperature rating of 150°C
for continuous.Operation&250°C.Under emergency over loader short circuit continuity even in fire because silicone rubber
burns into an insulating ash.it is resistant to moisture ozone radiation and chemicals.Being elastomeric in nature it is
flexible and flexibility is retained over wide range of temperature.(-55℃to 250°℃
