Embodiment Construction

[0011] Such as figure 1 As shown, a new type of heating cable, the cable core is composed of symmetrically arranged conductors 1, a conductive plastic layer 2 filled between the conductors 1, and an insulating layer 3 wrapped around the conductive plastic layer 2. The insulating layer 3 of the cable core The outer side is provided with a heat insulating layer 4 , and the insulating layer 3 and the heat insulating layer 4 are wrapped with an outer sheath 5 .

[0012] The heat insulating layer 4 is provided on the upper side or the lower side of the outer side of the insulating layer 3 .

[0013] The heat insulation layer 4 is an insulating belt or a thermal insulation belt.

[0014] The conductive plastic layer 2 is a functional macromolecular material processed by mixing resin and conductive substances in the same way as plastics.

[0015] Add a layer of heat insulation layer 4 on one side of the insulation layer 3, so that all the heat generated by the cable is transferred ...

Abstract

The invention provides a novel heating cable. The cable core of the heating cable is formed by conductors which are arranged symmetrically, a conductive plastic layer which is filled between the conductors, and an insulating layer wrapped on the conductive plastic layer, wherein one side of the outside of the insulating layer of the cable core is provided with a thermal insulation layer; the insulating layer and the thermal insulation layer are wrapped with an over sheath; the thermal insulation layer is arranged at the upper side or the lower side outside the insulating layer; and the thermal insulation layer is an thermal insulation belt or a heat preservation belt. The novel heating cable can solve the problem that the heat of a cable is dissipated to the surrounding so that heat loss occurs, and can prevent the heat dissipating toward the reverse direction of a heated object so that quick heating can be realized.

Description

technical field [0001] The invention relates to the field of cables, in particular to a novel heating cable. Background technique [0002] With the rapid development of science and technology, the depletion of resources, and the deteriorating environment, the country has considered the situation and put energy conservation and emission reduction on the agenda, and publicized and supervised it as an important item in the "Twelfth Five-Year Plan". In accordance with policy and market demand, energy-saving products have been developed one after another. As the second largest industry in China, the cable industry is imperative to develop low-consumption and high-efficiency products. [0003] At present, the structure of the commonly used heating cable is mainly composed of: conductor, conductive plastic layer, insulating layer and sheath layer. It has no single-sided (one-sided) heat insulation structure, which leads to the heat energy converted from electric energy being transf...
