Silicone-insulated cables are used when exposure to high temperatures and temperature variations would cause conventional PVC-insulated cables to become brittle. Silicone-insulated cables are preferably used in the metallurigical industry, steel works, hot-rolling mills, coking plants, foundaries, cement works, glass factories and ceramic plants as well as in the production of electric motors, in ships and aeroplanes, in heating equipment, and in lighting gear etc. The silicone rubber is resistant to vegetable and animal fat, many types of oil and diluted acids. No decomposition occurs when exposed to alcohol, plasticizers, alkaline solutions, saline solutions, etc. The insulation is fully tropicallized and resistant to oxygen and ozone. One of its exceptional features is its high flash point. Should the cable burn, an insulating silicon dioxide layer will remain on the conductor to render it short circuit proof.
