Automatic temperature control heating cable

Abstract

The invention discloses a self-temperature-control heating cable. The cable comprises a left side cushion block, a left threaded connector, a fixed round opening, a left cable connector, a cable, a wire pressing elastic piece, a positive power interface, a middle connector, a negative power interface, a right cable interface, a right heat preservation layer, a shell, a fastening hinge and a left heat preservation layer. The upper end of the left cushion block is movably bonded with the middle of the left threaded connector, and the fixed round opening is fixedly formed in the right end of theleft threaded connector. According to the self-temperature-control heating cable, the materials and strength are saved; the used heat preservation layer structure can well preserve heat and control temperature; the heating cable is suitable for being used as a heating cable, can well support work, saves materials and strength, guarantees environmental protection, meets the industrial standard, canbe continuously used, enables heating and temperature control to be more convenient; meanwhile, the cable reduces the occupied space through the external resistance heat preservation layer, and is suitable for being used as the heating cable of a temperature self-control structure.

Description

technical field [0001] The invention relates to the technical field of self-temperature-control heating cables, in particular to a self-temperature-control heating cable. Background technique [0002] Self-regulating heating cables are generally composed of continuous and seamless metal sheaths, single or multiple resistance wires and tightly compacted magnesium oxide insulation layers, so they are especially suitable for heat tracing of high-temperature pipelines. In places with strong corrosion, a PVC jacket can be added, which can be easily connected to the power supply. In addition, the heating element can be made into various shapes according to the needs of use. The cold end of the heating cable is welded by the connector. The core of the self-limiting temperature heating cable is a very complex polymer compound, which is composed of a variety of materials and conductive media. After specific chemical changes and physical treatments Extruded, a continuous parallel he...

Problems solved by technology

[0003] There are many finished self-temperature-controlling heating cables on the market, but they cannot be used to add resistance materials, so the temperature control effect is not good, and there is an upper limit for heating use, which affects the overall quality. Based on this, a self-temperature-controlling heating cable is proposed. solve the problem
