Overview of Skin-Effect Heating Cables with Soft Steel Cores
The steel-core skin-effect heating cable consists primarily of a soft steel core, copper conductors, and an insulating layer. The soft steel core primarily bears the tensile forces generated during installation, thereby enhancing the overall tensile strength of the cable. The copper conductors are responsible for transmitting electrical current. The insulating layer typically comprises a double-layer fluoroplastic material, which serves mainly to provide insulation, high-temperature resistance, and corrosion resistance. The primary application scenarios for steel-core skin-effect heating cables include heating hollow sucker rods in underground wells and providing core-through thermal tracing for long-distance pipelines.
