Abstract
The utility model discloses a parallel self-control-temperature heat-tracing cable, and the cable comprises three conductive core wires which are arranged in a parallel manner. A PTC material layer wraps the core wires. The core wires and the PTC material layer form a heat-tracing tape. The central part of the heat-tracing tape is a main heat-tracing tape, and the parts, located at two sides of the main heat-tracing tape, of the heat-tracing tape are auxiliary heat-tracing tapes. The peripheries of the three heat-tracing tapes are wrapped by an insulating layer which is made of insulating materials. The insulating layer is wrapped by a thermal insulation layer which is made of thermal insulation materials. The thermal insulation layer is wrapped by a shielding layer which is wrapped by a protection sheath. The protection sheath is made of wear-resistant composite materials. Wear-resistant particles are discretely distributed in the basic body of the protection sheath. The thickness of the thermal insulation layer is greater than the thickness of the shielding layer, and the thickness of the protection sheath is greater than the thickness of the thermal insulation layer. The cable provided by the utility model is simple in structure, is high in heating efficiency, and is long in service life.
