Problems solved by technology

[0005] The length of service life of the cable depends on the quality of the cable and the environment in which the cable is installed. At present, the quality of the cable itself is relatively high, but the environment in which the cable is installed is relatively complicated, especially in severe cold areas, where the low temperature has a great impact on the cable, and it i

Embodiment 1

[0049] see Figure 1-2 , an internal heating type antifreeze cable for severe cold regions, comprising an internal heating type antifreeze layer 1 and a cable core 2 embedded in the internal heating type antifreeze layer 1, the internal heating type antifreeze layer 1 is provided with a supplementary hole 5, There are several evenly distributed inflatable heads 3 connected to the internal heating antifreeze layer 1, and the inflatable heads 3 are connected to the supplementary holes 5, and an inflatable head 3 is set at a certain distance, which can avoid the difficulty of inflating caused by too long cables , There are a plurality of evenly distributed cold-sensing outer scales 4 between the inflatable heads 3 .

[0050] see Figure 3-4 The cold-sensing outer scales 4 include an obliquely inserted thermal insulation sheet 41 and a pull-change cold-shrinkable mandrel 42 embedded in the obliquely-inserted thermal insulation sheet 41, and the pull-variable cold-shrinkable mandr...

Abstract

The invention discloses an internal heating type anti-freezing cable for a severe cold area and an anti-freezing method thereof, belongs to the technical field of cables, and can realize that a contraction action is triggered after external cold is sensed by arranging cold sensing outer coating scales outside the cable, so that the cable can be prevented from being frozen. Pre-filled magnetic heat-generating microspheres are subjected to powder scraping and adsorption by virtue of shrinkage action, and then an external gap is opened to be communicated with the outside after the magnetic heat-generating microspheres are shrunk to a certain extent, so that a small amount of external air enters the cable and is subjected to an oxidation reaction of releasing heat with the scraped powdery magnetic heat-generating microspheres, a gentle heating environment can be formed in the cable, on one hand, the cable can be assisted to resist external cold, on the other hand, burnout caused by excessive heat release can be avoided, technicians can regularly supplement the magnetic heat generation microspheres to realize autonomous low-temperature protection action of the cable, the use safety of the cable in severe cold areas is effectively improved and the service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically relates to an internal heating type antifreeze cable and an antifreeze method for severe cold regions. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, which have different definitions. [0003] Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating layer to transmit power or information from one place to another. [0004] Definition 2: It is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center, and the entire outer wrap Has a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0005] The length of service life of the cable depends on the ...
