Application

Silicone rubber is resistant to extreme temperature conditions, as for high (up to 180 °C, briefly even to 250 °C), so also for low (-60 °C) temperature. It has a high point (temperature) of inflammability, it is halogen-free, releases no corrosive gases at combustion, and around the conductor is formed additional insulation of silicone-oxide ashes. Due to a higher electrical resistance, tinned copper is also more suitable for higher temperatures (up to 220 °C) than bare copper. Such composition of these conductors makes them applicable in extreme temperature environment, for inst. in steel production, aircraft industry, same as in shipbuilding, cement plants and glass and ceramics factories, in electric power plants etc. They are also suitable for inner wiring of lighting, heating elements, burners, furnaces etc.
