Heat Resistant Silicon Elastomer Cables

Silicon rubber insulation has excellent electrical properties & high thermal resistance. It allows conductor temperature rating of 150C for continuity operation & 250C under emergency over load. It maintains circuit continuity even in fire because silicon rubber burns into an insulating ash. It is resistant to moistures, ozone radiations and chemical. Being elastomeric in nature it is flexible is retained over wide range of temperature (+ 250°C to 55°C )

Specialities:

High temperature operation, Excellent electrical properties, Moisture abrasion resistant, Long Service Life, Light weight and good antifriction properties, flexibility over wide range of temperature, High Thermal Conductivity, Resistance to ozone and sunlight.
