nVent Electric plc introduced the nVent RAYCHEM STS-HV cable, the latest addition to the nVent RAYCHEM STS Skin-effect Tracing System portfolio of longline heating solutions. This new 10 kV system delivers circuit length capabilities up to 50 km (31 miles) with operating temperatures up to 150°C (302°F) for the world's longest heated pipeline installations. Increased circuit lengths and maximum durability: The nVent RAYCHEM STS-HV skin-effect cable doubles the circuit length capability compared to existing STS offerings, which reduces overall project budget and scope related to the development of new electrical sub-station infrastructure.

This is especially beneficial for pipelines spanning remote and undeveloped regions. This system is also engineered for installation pull lengths of up to 500 m (1,640 ft) to minimize the number of splice connection points throughout the heated pipeline system. The IECEx certified hazardous and non-hazardous rated system and components include watertight IP56 rated splice enclosures and IP66 rated power, jumper and end termination enclosures designed to withstand the harshest environments spanning rugged and remote regions.

nVent RAYCHEM STS Skin-effect Tracing Systems: nVent RAYCHEM STS systems have been installed on both the world's longest heated and insulated pipeline and sulphur transport pipeline, and in hundreds of additional installations and facilities owned by the world's largest oil and gas producers and chemical refiners. nVent RAYCHEM STS systems are renowned for their reliability, high-caliber performance and long operational life, built upon over 40 years of experience designing, installing and commissioning in excess of 2.5 million meters of trace-heated pipelines and bundled solutions spanning hundreds of installations. nVent RAYCHEM STS-HV – now available globally – further solidifies nVent's unique capabilities in the temperature-critical pipeline transportation space.
