HEAT RESISTANT (HR) HIGH TEMPERATURE PTFE CABLE



Heat Resistant High Temperature (HR) Cables are used as power cables in plants where there is high temperature environment and ordinary PVC cables can not be used such as near rotary kilns, furnaces, boilers etc. Due to the high temperature around the furnace, the electrical wiring of motors , control panels etc. near the furnace gets damaged very frequently, which compels the replacement of cables at periodic intervals leading to precious loss of productivity. This problem is greatly reduced by using High temperature PTFE insulated H.R. cables H.R. Cables made by Tefkot Cable Company are made by using PTFE insulation which is a High Temperature insulating material having excellent electrical properties and is inert to almost all chemicals and it also does not age. These properties make it suitable to be used as power cable in industries such as steel, cement, fertilizer, chemical etc.
