HTS is a single conductor series resistance heat tracing cable installed as three cables in a three-phase system, for freeze protection and temperature maintenance of long pipelines up to 5 km from a single supply point. A typical application is maintaining the temperature of crude and fuel oil in above-ground and buried transfer lines. It delivers up to 50 W/m and runs on up to 1000 V three-phase. It has silicone insulation and is available with a metal braid or jacket. It is explosion-proof, ATEX, IECEx and FM certified for hazardous areas.
