Application
These are silicone multicore cables screened with braiding 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.

Properties
Advantages : Hardly changes of dielectric strength and the insulation resistance also at high temperatures, high ignition or flash point, in case of fire, 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.
Behavior in Fire : Flame propagation test according to EN 60332 – 1 – 2.
