Embodiment Construction

[0014] like figure 1 and figure 2 As shown, a pair-twisted double-conducting carbon fiber heating cable is mainly composed of a sheath 1 and a carbon fiber heating wire 2. The sheath 1 is made of silica gel or cross-linked polyethylene or low-smoke halogen-free material or PVC, and the carbon fiber heating wire 2 is made of Composed of several carbon fibers 3 and an insulating protective layer 4, two carbon fiber heating wires 2 are twisted to each other inside the sheath 1 in a spiral shape, and the insulating protective layer 4 is a Teflon insulating layer or an irradiated cross-linked polyethylene insulating layer or XLPE insulation.

[0015] The working principle of the heating cable of the present invention is: the carbon fiber electric heating body is a black body material, the electrothermal conversion efficiency is 30% higher than that of metal heating, and the electric heating efficiency is about 100%. 1.35 times that of carbon fiber heating cables, and the carbon ...

Abstract

A pair-twisted double-guide carbon fiber heating cable mainly consists of a protective bushing and carbon fiber heating wires; the carbon fiber heating wires consist of a plurality of carbon fibers and insulation protecting layers; and carbon fiber heating wires are pair-twisted spirally inside the protective bushing. The pair-twisted double-guide carbon fiber heating cable has the excellent features of scientific and rational design structure, high-temperature resistance, ageing resistance, anti-interference, high efficiency, energy conservation and good thermal stability; because of no radiation, the pair-twisted double-guide carbon fiber heating cable does not need to be shielded and the production cost is saved greatly.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a pair-twisted double-conducting carbon fiber heating cable. Background technique [0002] Carbon fiber is a kind of fibrous carbon material, which has the characteristics of corrosion resistance, oxidation resistance (metal is easy to oxidize and cause local breakdown), high stability, and long life (generally able to reach 100,000 hours of stable work at 300 degrees Celsius). Its strength is higher than that of steel, its density is lower than that of aluminum, it is more corrosion-resistant than stainless steel, more resistant to high temperature than heat-resistant steel, and can conduct electricity like copper. It is a new material with many valuable electrical, thermal and mechanical properties. The aircraft made of composite materials made of carbon fiber and plastic is not only light, but also consumes less power, has high thrust and low noise; the disk of an el...
