The invention discloses a novel self heating cable and relates to a signal transmission device. The novel self heating cable comprises a conductor, wherein the conductor is externally sequentially provided with an insulation layer and a sheath layer, the insulation layer is a four-layer composite structure and sequentially comprises an organic insulation layer, an inner inorganic insulation layer,an outer inorganic insulation layer and a flame retardation layer from inside to outside, the sheath layer is externally provided with a fireproof layer, the fireproof layer is prepared from mica tape, and an electrical heating element contacting with the conductor is further arranged between the conductor and the insulation layer. The novel self heating cable is advantaged in that the structureis simple, the electrical heating element is added to the cable, self heating of the cable is realized through the electrical heating element, low temperature cable laying requirements are satisfied,the fireproof layer is further arranged, and safety is enhanced.
Description
technical field [0001] The invention relates to a signal transmission device, in particular to a novel self-heating cable. Background technique [0002] The current cables generally do not have the self-heating function, and a few of them are not safe enough. There is an urgent need for a safe self-heating cable on the market. Contents of the invention [0003] The purpose of the present invention is to solve the difficult problem of the current cable and provide a new type of self-heating cable with high safety performance. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: a new type of self-heating cable, including a conductor, an insulating layer and a sheath layer are arranged outside the conductor in turn, and the insulating layer is a four-layer composite structure. To the outside, there are organic insulating layer, inner inorganic insulating layer, outer inorganic insulating layer and flame retard...
