The invention discloses an anti-corrosion anti-tensile electric heating band. The anti-corrosion anti-tensile electric heating band comprises a body, the body comprises conductors, a PTC layer, an insulation layer and a shielding layer, and the multiple conductors are arranged inside the body. The cross section of the body is of a round structure, multiple optical fibers are arranged outside the conductors and tangent to the conductors, the conductors are wrapped with a woven layer, the PTC layer is arranged at the gaps among the woven layer, the optical fibers and the conductors, the woven layer is tightly wrapped with a reinforcement layer in an extruded mode, the reinforcement layer is wrapped with the insulation layer and the shielding layer sequentially from inside to outside, and the shielding layer is wrapped with an outer protection sleeve in an extruded mode. The anti-corrosion anti-tensile electric heating band has the advantages of being reasonable in structural design, high in heat conversion efficiency, long in service life and the like.
Description
technical field [0001] The invention relates to a heat tracing device, in particular to an anti-corrosion and anti-stretch electric heating band. Background technique [0002] At present, with the development of science and technology, the fields of petroleum, chemical industry and medicine are also making rapid progress. The electric heating cable is a special cable that generates heat after being heated by electric energy. It is currently widely used in various fields. Therefore, people are interested in The requirements for electric heating belts are getting higher and higher, but the existing electric heating belts have low heat conversion efficiency due to their unreasonable structural design, which not only wastes resources, but also has low work efficiency, which brings great losses to enterprises. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide an anti-corrosion ...
