SiHF

Application

These are silicone multicore cables for use at the areas where extreme temperature changes. Silicone cables are halogen – free cables and are especially suited for installation in power stations. They have also found their use in the steel producing industries, aviation industry, ship building as well as in ceramic, glass and cement factories. Due to elastical characteristic of core insulation, these are used as flexible connection cable.

Standards

Adapted to DIN VDE 0250 part 1 and part 816.

Properties

Advantages: The dielectric strength hardly changes even at high temperatures. The cable has high ignition or flash points. In case of fire, it forms an insulating layer of SiO2

Resistant to: High molecular oils, fats from vegetables and animals, alcohols, plasticisers and clopenes, diluted acids, dyes and salt dissolution, oxidation substances, tropical influences and weather, lake water, oxygen and UV.

Halogen – Free: According to IEC 60754 – 2.

Behaviour in Fire: Flame propagation test according to EN 60332 – 1 – 2. For laying as a fixed installation only in open or ventilated pipe systems as well as in ducts. Otherwise the mechanical properties of Silicone are reduced by the enclosed air at temperatures exceeding 90°C.
