These cables are used in all areas of low mechanical load where high and low temperatures can have a direct effect, i.g. in ship building, in iron and steel works, in smelting plants, power plants, foundries, coking plants, glass and ceramic works, cement works, for high-power lighting fixtures and spotlights, solarium and sauna installations.

Characteristic features

•  Temperature-resistant from - 60 °C to + 180 °C, for short periods to + 250 °C, flexible at low temperatures down to - 25 °C in continuous operation.
•  These cables are approved to supply temperature class H up to 180 °C.
•  In the event of fire, no fire support; retention of the insulation and low smoke emission.

Durability

•  The silicone compound is resistant to ozone, oxygen and weathering.
•  Resistant to transmission oil, acetone, aniline, boric acid, brake fluids, methanol, engine oil, sulphur dioxide, tartaric and citric acid, sea water as well as vegetable and animal fats.
•  Refer also to the Table of Technical Guidelines for other chemical resistance properties of silicone compounds.
