Carbon fiber composite heating cable

Abstract

The invention discloses a carbon fiber composite heating cable which comprises a carbon fiber core wire and an epoxy resin rubber sheath. The carbon fiber core wire comprises two carbon fiber lead wires, two Teflon high-temperature-resisting plastic layers are arranged outside each carbon fiber lead wire, and a heat-conducting insulation layer is wrapped outside the carbon fiber core wire. A plurality of annularly-arranged carbon fiber core wires are arranged in the epoxy resin rubber sheath, and heat-conducting insulating compound is filled between the epoxy resin rubber sheath and the carbon fiber core wire. The carbon fiber composite heating cable is suitable for public buildings, residential buildings, road snow melting, pipeline heat preservation and the like, is free of electromagnetic radiation, long in service life, strong in controllability, capable of really achieving family splitting, room splitting and region control, convenient to operate, simple and easy to operate, simple in installation and low in operation cost, utilizes far infrared heat dissipation, can promote blood circulation and blood vessel dilatation of a human body and enable the body interior to be warm and facilitates energy saving, and the heat conversion rate reaches up to 99%.

Description

technical field [0001] The invention relates to a carbon fiber cable, in particular to a carbon fiber composite heating cable. Background technique [0002] The traditional heating cable mainly uses alloy resistance wire as the heat source inside, and the outside is composed of insulating layer and outer sheath. The far-infrared radiation is transmitted to the heated body, and its disadvantage is that the heating efficiency is relatively low, about 65%; the starting current load is large. The metal alloy heating element will produce strong electromagnetic radiation to the human body, and long-term electromagnetic radiation will endanger human health. And this kind of cable has a short service life, and long-term use will cause oxidation of the outer insulating layer and outer sheath, which will lead to electric leakage and the like, which will pose a great safety hazard to the human body. [0003] Contents of the invention [0004] The invention provides a carbon fiber ...

AI Technical Summary

Problems solved by technology

[0002]The traditional heating cable mainly uses alloy resistance wire as the heat source inside, and the outside is composed of an insulating layer and an outer sheath. The heating cable in the layer transmits heat energy to the heating body through heat conduction and far-infrared radiation at a certain distance. The disadvantage is that the heating efficiency is relatively low, about 65%; the starting current load is large

Moreover, this kind of cable has a short service life, and long-term use will cause oxidation of the outer insulating layer and outer sheath, which will lead to electric leakage, etc., which will pose a great safety hazard to the human body.
