Silicone rubber insulated and sheathed flexible cable with glass fiber braid

	Application	Standards
	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 cables makes them applicable in extreme temperature environment, for inst. in steel production, aircraft industry, shipbuilding, cement plants and glass and ceramics factories, in electric power plants etc. They are also suitable for wiring of lighting, heating elements, burners, furnaces, saunas, solariums etc. To retain its mechanical properties at temperatures higher than 90 °C, silicone rubber needs to be properly ventilated or laid outdoor or in tubes. Glass fibers increase mechanical resistance of cable.	DIN VDE 0250 part 1 HRN HD 22.15 S1
