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

Abstract

A method for manufacture an alloy wire heating cable of includes such step of 1, extruding the insulating sleeve of wire core on the outer side of wire core conductor wire to obtain a heating wire core; 2, combining the two heating cores into one, and extruding a layer of alloy wire inner membrane sleeve on the outside of the two heating wire cores; 3, extruding to produce uniform heat distribution alloy wire, and laying the uniform heat distribution alloy wire on the outer side of the inner film sleeve of the alloy wire; 4, extruding a layer of alloy wire out membrane jacket on the outer sideof the alloy wire inner membrane jacket with uniformly distributed heat alloy wire; 5, extruding a layer of out sheath on that outer side of the outer film sheath of the alloy wire. The invention provides an alloy wire heating cable processing method, which can make the temperature at each position of the heating cable as close as possible.

Description

technical field [0001] The invention relates to the technical field of heating cable production technology, in particular to a processing method for alloy wire heating cables. 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 i...
