Anti-radiation carbon fiber heating cable

Abstract

The present invention discloses an anti-radiation carbon fiber heating cable. The anti-radiation carbon fiber heating cable comprises a heating wire harnesses consisting of carbon fibers, wherein an insulation protection layer is wrapped outside the heating wire harnesses; a conductive plastic layer is wrapped outside the insulation protection layer; conductive wires are laid outside the conductive plastic layer in parallel and are clung to the conductive plastic layer in parallel; and a protective sheath is wrapped outside the conductive wires and the conductive plastic layer. A novel shielding layer is arranged in the cable, so that the cable not only can be adaptive to softness and bend-ability of the carbon fibers, is good in shield effect, convenient to package and construct, but also is easy to manufacture, relatively low in cost and long in service life.

Description

technical field [0001] The invention relates to a heating cable, in particular to a carbon fiber heating cable which does not generate harmful electromagnetic radiation. Background technique [0002] Heating cables are widely used for heating floors, roads, etc. At present, the common heating cables mainly include metal heating cables and carbon fiber heating cables. The former uses metal resistance wire as a heat source and is wrapped with an insulating layer. It produces harmful electromagnetic radiation to the human body, so a radiation shielding layer made of wire mesh or aluminum foil is wrapped outside the insulating layer to reduce the damage of harmful electromagnetic radiation to the human body, and a protective coat is also provided on the outermost layer. Carbon fiber heating cables use carbon fiber bundles as a heat source, and part of the heat generated is released in the form of infrared rays that are beneficial to the human body. This advantage is not availabl...

AI Technical Summary

Problems solved by technology

Therefore, the radiation shielding layer of the metal heating wire cannot be used on the carbon fiber cable. If the shielding layer made of the carbon fiber heating cable is wrapped with metal mesh or aluminum foil, it cannot adapt to the soft and easy-folding characteristics of the carbon fiber. When winding, the metal shielding layer is easily broken by fatigue or cracked by extrusion, which greatly reduces the service life

In addition, wire mesh is used as a shielding layer, and there are defects such as complicated and time-consuming wire mesh weaving process, slow production speed, high cost, etc., and the hole shape of the wire mesh cannot completely shield the harmful electromagnetic radiation generated.
