Problems solved by technology

[0004] When the cable is laid, it is usually exposed outside. In winter, when the temperature is low, the protective layer of the core is easy to become brittle. It will cause some cable cores to be exposed, reducing the service life of the cable, and there will be a greater safety hazard

Embodiment 1

[0038] see figure 1 , a terminal self-heating type freeze-resistant self-repairing cable, comprising a plurality of wire cores 1, the outer ends of the plurality of wire cores 1 are wrapped with an inner insulating layer 2, and the outer ends of the inner insulating layer 2 are wrapped with an outer protective layer, and the outer protective layer includes The inner protection layer 31 wrapped outside the inner insulation layer 2, the outer insulation protection layer 32 located at the outermost layer, and the repair interlayer 33 arranged between the inner protection layer 31 and the outer insulation protection layer 32, the repair interlayer 33 is near the inner end A ring-shaped repair cavity 4 is excavated, and the ring-shaped repair cavity 4 is filled with repair glue, which can be a rubber repair agent. The repair interlayer 33 is inlaid with a plurality of evenly distributed capillary dispersion bundles 5, and the outer ends of the capillary dispersion bundles 5 are one ...

Abstract

The invention discloses a tip self-heating type anti-freezing self-repairing cable, and belongs to the field of cables. The tip self-heating type anti-freezing self-repairing cable is characterized inthat in winter, under the condition of low temperature, through self-heating repairing particles, on one hand, self-cracking water balls in the self-heating repairing particles are solidified at lowtemperature and are gradually dissolved when the midday air temperature rises again, under the alternating of continuous thermal expansion and cold contraction, deionized water in the self-cracking water balls overflows and reacts with the self-heating repairing particles to generate heat, so that the surface of the cable has a certain temperature, and the cracking probability of the cable due toembrittlement in winter is further effectively reduced; and on the other hand, when the cable is locally damaged, capillary dispersion bundles transport a repair glue solution to the damaged part to simulate the incrustation phenomenon of the skin broken part, the effect of fixed-point coagulation repair of the damaged part is achieved, the service life of the tip self-heating type anti-freezing self-repairing cable can be effectively prolonged, meanwhile, the situation that a wire core is accidentally exposed can be effectively avoided, and compared with the prior art, the potential safety hazard is remarkably reduced.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to a tip self-heating type frost-resistant self-repairing cable. Background technique [0002] The cable is mainly composed of the following 4 parts. ① Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, XLPE cables, etc. ③ Sealing sheath: protect the insulated wir...
