Abstract

The invention relates to a self-temperature limiting heat tracing belt with a dual-layer resin conductor and a manufacturing method thereof. The self-temperature limiting heat tracing belt is characterized by comprising a metal conductive electrode, a resin conductor layer, a heating element and an insulation layer. A shielding layer or a sheath can also be arranged outside the insulation layer. In the invention, the formulas of the resin conductor layer and the heating element are improved, and through the implementation of the technical scheme of the invention, and the problems existing in the aspects that the power attenuation of the traditional heat tracing belt is serious, the starting current of the traditional heat tracing belt becomes big, the heat tracing belt is burnt out frequently, the performance is not stable and the like can be well solved. The invention greatly improves the performance of the heat tracing belt, has the advantages of small starting current and high heat tracing belt temperature and is suitable for the industrial application.

Description

1. Technical field: [0001] The invention belongs to the field of explosion-proof electric heating products, and mainly relates to an electric heating equipment and a manufacturing process, in particular to a double-core double-layer structure self-limiting temperature tracing cable with double-layer resin conductors and a manufacturing method thereof. 2. Background technology: [0002] With the advancement of society and the improvement of automation, electric heating and electric heat tracing technology has become more and more widely used. Constant power heating tape and self-limiting temperature tracing tape have been used in the industrial field for many years. The structure of this self-limiting temperature heating cable is to coat a layer of PTC heating element on two parallel electrode conductors to form a parallel circuit, and then coat the heating element with a layer of insulation to make a basic heating element. After the self-limiting temperature heating cable of...
