Carbon fiber heating cable

Abstract

The invention discloses a carbon fiber heating cable which comprises a heating body. The heating body is composed of carbon fiber. The heating body is covered by a protective sleeve. An insulating layer is arranged outside the protective sleeve. The insulating layer is composed of an inner insulating layer and an outer insulating layer. The outer insulating layer covers the inner insulating layer. The inner insulating layer is made of a high temperature resistance material. The outer insulating layer is covered by a shielding layer. The shielding layer is covered by a protective layer. A ground wire is arranged between the shielding layer and the protective layer. The carbon fiber heating cable has the advantages of high electricity and heat conversion efficiency, electric power saving, good conductivity, impact current prevention, long service life and good insulating performance.

Description

technical field [0001] The invention relates to a cable, in particular to a carbon fiber heating cable. technical background [0002] Carbon fiber is a fibrous carbon material with corrosion resistance, oxidation resistance (metal is easy to oxidize and cause local breakdown), high stability, long life (100,000 hours of stable work can be generally achieved at 300 degrees Celsius), heat conversion rate High (above 97%) and other characteristics. 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 electronic computer made of carbon fib...

Problems solved by technology

Since the civil electricity in our country is 50HZ alternating current, when using this kind of heating cable, a periodically changing electromagnetic wave field will be generated, and the user will be in such an electromagnetic wave field for a long time, even though the cable heats up in two wires and forms a loop , effectively overcome electromagnetic radiation, but after all, it will have microscopic adverse effects on people

[0005] The safety of the heating cable used for floor heating is the most important during use. However, the insulation layer of the existing heating cable uses a single layer of polyethylene insulation material. This insulation material is easy to soften in a high temperature environment, and it will cause overload when it is used for a long time. The current is easy to break through the insulation layer, which will lead to serious consequences such as leakage and damage to the heating cable, which greatly shortens the life of the heating cable

Therefore, when the heating cables are used as electric floor heating, they cannot be covered with carpets or heavy objects, otherwise there will be potential safety hazards
