Low-temperature explosion-proof heat tracing cable

Abstract

The invention discloses a low-temperature explosion-proof heat tracing cable, and relates to the technical field of heat tracing cables, the low-temperature explosion-proof heat tracing cable comprises a cable core body, and the cable core body comprises a tiled straight line section part and a bent section part perpendicular to the straight line segment section ; the plane where the wire core body of the bending section part is located is perpendicular to the planes where the wire core bodies at the two ends are located, a conductive plastic layer, an insulating layer, a shielding layer, a heat preservation layer and a cable jacket are sequentially arranged on the surface of each wire core body, and isolation layers are arranged in the cable jacket at equal intervals in the direction of the wire core bodies. And the surface of the cable jacket is axially provided with anti-stretching support ribs at equal intervals. By arranging the straight line section part, the bent section part, the heat preservation layer, the thickened cable jacket, the isolation layer inside the cable jacket, the anti-stretching supporting ribs outside the cable jacket and the woven explosion-proof layer, the problem that the heat tracing cable is prone to being affected by the environment after working in a low-temperature environment for a long time, and consequently aging or damage or burst is causedis solved.

Description

technical field [0001] The invention relates to the technical field of heat tracing cables, in particular to a low-temperature explosion-proof heat tracing cable. Background technique [0002] Heating cable, also known as electric heating cable, is an electronic component with heat tracing effect after power supply. The overall structure and appearance are similar to other types of cables. Because of its simple and convenient installation, it is favored by consumers. The heating cable has the function of heating and heat preservation, and can be used in most insulation fields. The common outdoor pipes and equipment use the heating cable to keep warm and prevent freezing. And the use of heating cables on the ground and roof to melt snow is now widely used. Consumers can also use personalized fields according to their own needs. For example, heating cables are installed on the bed to replace traditional electric blankets. [0003] When the heating cable is used outdoors, esp...
