Explosion-proof corrosion-resistant series electric tracing band

Abstract

The invention discloses an explosion-proof corrosion-resistant series electric tracing band in the technical field of electric tracing bands. The explosion-proof corrosion-resistant series electric tracing band comprises a bus, an insulating sleeve, an inner insulating layer, a heating wire, an outer insulating layer, a heat transfer sleeve and a sheath, two groups of buses are arranged; the number of the insulating sleeves is two, and the two insulating sleeves are respectively arranged outside the two buses. The inner insulating layer is arranged outside the two groups of insulating sleeves; the heating wire is wound outside the inner insulating layer; the outer insulating layer is arranged outside the heating wire; the heat transfer sleeve is arranged outside the outer insulating layer; and the sheath is arranged outside the heat transfer sleeve. The explosion-proof corrosion-resistant series-connection electric tracing band can avoid the situation of explosion caused by too high heat in the outer insulating layer.

Description

technical field [0001] The invention relates to the technical field of electric heating cables, in particular to an explosion-proof and corrosion-resistant series electric heating cable. Background technique [0002] Heat tracing means that the heat provided by the outside to the pipeline or equipment is equivalent to the heat loss of the pipeline or equipment to maintain the temperature of the pipeline or equipment. At present, the electric heating cable is generally installed on the surface of the heated part to achieve the heat tracing effect. . [0003] The heat transfer effect of the traditional series electric heating cables is not good, causing the high temperature heat generated by the internal heating wire to accumulate inside, which is likely to cause bursts in the electric heating cables, and as the use time increases, the electric heating cables are easy to be corroded. Affect. Contents of the invention [0004] The object of the present invention is to provi...
