Heat Resistant Cables - An Overview

Heat Resistant cables are used in applications where there is a risk of fire or where the equipment has to function at high temperatures for a specific period of time.fire resistant

Examples are Thermal power stations, nuclear installations, Airports, Railways. 

Heat Resistant cables are made with special fire-resistant insulation.  They also have an outer heat barrier which prevents the heat from reaching the inner areas of the conductor.

Heat Resistant cables can work at high temperatures such as 660, 750 or 950 degrees.

When the insulation of a normal cable burns, hazardous halogen gases are released.  Fire Resistant cables are made with a special compound which emits very less smoke and does not emit hazardous gas.

Heat Resistant cables are specified in terms of the temperature they can withstand for a specific time such as 15, 30, 60, 90 and 120 minutes of operation.
