Abstract

The invention belongs to the technical field of electric heat tracing bands and specifically relates to a high temperature self-regulating electric heat tracing band. A technical problem which needs to be solved in the invention is to put forward a high temperature self-regulating electric heat tracing band so as to solve a problem that a conventional high temperature self-regulating electric heattracing band is high in production cost. To solve the above technical problem, the invention puts forward the high temperature self-regulating electric heat tracing band comprising a PTC material layer, an insulation layer, a metal wire shielding layer and a protection sleeve layer; the PTC material layer is of a flat structure, and two parallel buses are wrapped in the PTC material layer. The band disclosed in the invention has effects of low installation and operation costs and convenient-to-maintain property.

Description

technical field [0001] The invention belongs to the technical field of heating cables, in particular to a high-temperature self-limiting temperature electric heating cable. Background technique [0002] At present, the self-limiting temperature heating cables used in the domestic market are basically low-temperature self-limiting temperature heating cables and medium-temperature self-limiting temperature heating cables, while the formula system of high-temperature self-limiting temperature heating cables is extremely imperfect, and the production cost High, unable to be widely used, the actual use of this product mainly depends on imported products, or use constant power electric heating cable products as a substitute. Contents of the invention [0003] According to the deficiencies of the prior art above, the technical problem to be solved by the present invention is to propose a high-temperature self-limiting temperature heating cable, which solves the current high-tempe...
