An alloy wire evenly distributed heat-generating cable

Abstract

The invention discloses an alloy wire uniformly distributed heat-generating cable, comprising two heating conductor cores and an outer sheath wrapped on the outer sides of the two heating conductor cores, each of the heating conductor cores comprises a wire core conductor wire and a wire core insulation sheath wrapped on the outer sides of the wire core conductor wire, uniformly distributed heat alloy wires are arranged in the outer sheath, and the uniformly distributed heat alloy wires are located on the outer sides of the wire core insulation sheath. The wire core conductor wire is a tin-plated copper stranded wire or a nickel-plated copper stranded wire; The wire core insulation sleeve is ethylene Vinyl acetate copolymer material; The outer sheath is made of perfluoroethylene-propylenecopolymer material. The invention provides an alloy wire uniformly distributes heat-generating cable. By arranging a heat-conducting alloy wire between a core insulation sleeve and an outer sheath ofthe heat-generating cable, heat at a high temperature is transferred to a position with low temperature along the length direction of the heat-generating cable through the heat-conducting alloy wire,so that the temperature at each position of the heat-generating cable can be as close as possible.

Description

technical field [0001] The invention relates to the technical field of heating cable products, in particular to a heating cable with uniform heat distribution of alloy wires. Background technique [0002] Heating cables are mainly used for the transportation of liquid objects in pipelines and the antifreeze and heat preservation of tanks, the maintenance of process temperature in industrial production, the heating of roads, ramps, crosswalks and other public transportation surfaces, and the heating of buildings such as eaves and floors. The structure of the heating cable mainly includes the heating conductor part made of alloy wire and the heating power adjustment part used to supply power to the heating conductor part and adjust the power supply. The heating cable can adjust the heating temperature and heating power, and can be applied to many different heating temperature occasions. [0003] Due to the long length of the heating cable, there will be certain differences in...

Problems solved by technology

[0003] Due to the long length of the heating cable, there will be certain differences in the external ambient temperature at different positions of the heating cable, thus affecting the heating power feedback at each position of the heating cable, which is not conducive to accurate temperature control of the heating cable; for this reason It is necessary to provide a heating cable with uniform distribution of alloy wire, which can make the temperature at each position of the heating cable as close as possible
