High-temperature resisting carbon fiber guide line

Abstract

The invention discloses a high-temperature resisting carbon fiber guide line which comprises a carbon fiber line core, mica tape layers, a conducting medium layer and an insulating layer. A plurality of mica tape layers are coated on the outer surface of the carbon fiber line core, the conducting medium layer is arranged outside the mica tape layers, and the insulating layer is coated outside the conducting medium layer. Each mica tape layer comprises a polyester thin film, mica paper and a glass cloth in sequence from external to internal, wherein the polyester thin film, the mica paper and the glass cloth are connected through glue adhering layers. The high-temperature resisting carbon fiber guide line has the advantages of saving metal resources, reducing cost and guaranteeing that the mica tape is not destroyed in the process of using and being good in fireproof and high-temperature resistance performance and high in practical value.

Description

technical field [0001] The invention relates to the field of wire rods, in particular to a high temperature resistant carbon fiber wire. Background technique [0002] In recent years, due to current overload and overheating of the wires, the insulation sheath of the wires is damaged and a short circuit is the main cause of fires. In order to reduce the occurrence of fire, there are fire-resistant wires in the prior art. This fire-resistant wire adopts wires to be wrapped with 2-4 layers of mica tape, and the outer extruded insulating sheath. The production process of this wire is complicated, the cost is high, and the production speed is slow, so that it cannot enter the civilian field. For this reason, some people have carried out research on overload-resistant fireproof wires, using mica tape outside the wire and extruding the insulation sheath outside, but in the actual winding test, the mica layer is easily damaged, causing the mica tape to open and expose the wire, whi...
