Problems solved by technology

In addition to this expensive layer structure, which also increases the cable diameter, the intentionally created air cushions inside the cable can significantly hinder the transfer of heat from the heating cable to the cable surface, resulting in a lower efficiency of the heating cable itself

Embodiment Construction

[0031] In order to improve the flexibility of the heating cable of the present invention, the conductor 1 shown in FIG. 1 includes a certain number of single resistance wires. The conductor insulator is marked with 2 and it has high temperature resistant polytetrafluoroethylene, where the term "polytetrafluoroethylene" as mentioned above also includes the following tetrafluoroethylene polymers with modified additives, although the amount of additives does not make the Polymers, like PTFE itself, cannot be processed by the melt.

[0032] In a preferred embodiment of the present invention, the polytetrafluoroethylene used has a tape or film material that is not sintered at the beginning, wherein the tape or film material is wound on the thermal conductor in an unsintered state, preferably overlapping, for example, not more than 50 %, and then sintered in the wound state through appropriate treatment. In this process, each tape layer will be melted or welded into a dense insulator....

Abstract

This invention provides one isolation electricity cable or band formed by PTPE with layer structure through At least one layer of adjacent melted fluoroplymer isolation layer without impact.

Description

Technical field [0001] The invention relates to an electric heating cable or an electric heating belt with a polytetrafluoroethylene insulation sheath arranged in a layer structure. Background technique [0002] In different applications, including heating corrosive media, it is known to use a coaxially arranged heating cable (DE-A 2850722), in which the heating cable is wrapped by a fluoropolymer as an insulating material. The insulator should be covered with a copper wire braid, and each copper wire should be additionally plated with nickel to avoid corrosion. The braid made of copper wires is the electric grounding cable of the heating cable, which is arranged in the cable to avoid accidental hazards caused by, for example, short circuits of conductive parts. The ground cable is also covered with an outer layer of plastic sheath, which is made of fluoropolymer, for example, to prevent corrosion by corrosive media in the environment. In addition to the advantages of a wide ra...
