Problems solved by technology
If it is not handled in time, it may cause serious consequences; if the surface temperature of the cable is too high, it will cause a serious fire accident, and if it is lighter, it will cause the aging of the cable materials to accelerate, the resistance of the cable conductor will increase, and the current will be unstable. Generally, they do not have the ability to dissipate heat and cannot self-regulate the temperature

Abstract
The invention relates to a constant temperature cable preparation method. The method comprises steps that 1 of conductive monofilament drawing, a conductive rod is drawn at the normal temperature by adrawing machine through a die hole of a drawing die; 2 of conductive monofilament annealing, after heating the conductive monofilament, the annealing process is performed to recrystallize; 3 of conductor twisting, the annealed multiple conductor monofilaments are twisted into a thicker conductor; and 4 of insulation glue dipping, the stranded conductor is moved to dip in insulating glue, and thesurface is coated with an insulation glue layer. The method is advantaged in that the temperature of the cable can be effectively controlled, the relatively constant temperature can be maintained within a certain range, on one hand, increase in resistance in response to increase of the temperature of the cable conductor can be prevented, stability of current transmission is guaranteed, the methodis suitable for electrical devices having high current stability requirements, on the other hand, the temperature is kept constant, aging of various materials of the cable can be effectively reduced,and service life is prolonged.
Description
technical field [0001] The invention relates to the field of cable manufacturing, in particular to a method for preparing a constant temperature cable. Background technique [0002] A cable is made of one or more mutually insulated conductors and an outer insulating layer, which transmits power or information from one place to another. When the power cable passes a certain load current, it will definitely generate heat. The higher the load current, the higher the temperature of the cable surface. If the treatment is not timely, it may cause serious consequences; if the surface temperature of the cable is too high, it will cause a serious fire accident, and if it is light, it will cause the aging of the cable materials to accelerate, the resistance of the cable conductor will increase, and the current will be unstable. Generally, they do not have the ability to dissipate heat and cannot self-regulate the temperature. Contents of the invention [0003] The invention propo...
