Suitable where PVC-insulated cables become brittle due to high temperature variations.
Silicone-insulated single cores are preferably used in the metallurgical industry, steel works, hot-rolling mills, coking plants, foundries, etc. The insulation consists of silicone rubber. It is resistant to vegetable and animal fat, many types of oil and diluted acids. No decomposition occurs when exposed to alcohol, alkaline solutions, etc.
The insulation is resistant to oxygen and ozone. Should the cable burn, an insulation silicone dioxide layer will remain on the conductor to render it short circuit proof.
