Explosion-proof self-regulating heating cable GTG-KABEL1-65

Product Description

Flexible heating cable with self-regulating temperature is designed for heating and maintaining the process temperature of automation objects, tanks, pipelines, and any other objects that require additional protection from freezing and icing.

At low temperatures, the heating element material contracts, creating multiple conductive paths of carbon material, thereby reducing electrical resistance. When an electric current passes through the heating element, thermal energy is released.

In warmer sections of explosion-proof heating cable, the heating element material expands, reducing the number of conductive paths. The electrical resistance of the heating element material increases, resulting in reduced heat generation.

Operating principle of the GTG-KABEL1 explosion-proof flexible heating cables: In hot sections of the heating cable, the expansion of the heating element material almost completely disrupts the conductive paths. This causes the material's electrical resistance to become very high, significantly reducing thermal energy release.

The scope of application is explosion-hazardous areas of premises and outdoor installations, in accordance with the assigned explosion protection marking, the requirements of GOST IEC 60079-14-2013 and industry safety rules governing the use of this equipment in explosion-hazardous areas.
