Problems solved by technology

[0006] Aerial cables need to dissipate the heat generated during use, but due to the high protection of the cable, it will restrict the heat dissipation capacity of the cable. Once the cable accumulates too much heat and cannot be dissipated in time, the cable transmission performance will decline or even the cable will be burned. risks of

Abstract

The invention discloses a humidity-control and heat-dissipation type aerial cable, and belongs to the technical field of cables. Natural rainwater can be collected by arranging a plurality of humidity-control and heat-dissipation balls at the lower end of the cable, and when heat of the cable can be dissipated in time, the humidity-control and heat-dissipation balls are in a separated state, so that the rainwater can be fully collected and stored; when the heat of the cable cannot be dissipated in time, the stored rainwater can be conveyed for heat dissipation of the cable by actively triggering the merging action of the humidity-control and heat-dissipation balls, on one hand, the efficient heat dissipation efficiency of the cable can be always kept, and the good working temperature of the cable is maintained; on the other hand, the collected rainwater can be reasonably utilized, the utilization rate of the rainwater is improved, and therefore the good working state of the aerial cable is effectively improved.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically relates to a moisture-controlling and heat-dissipating overhead cable. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. [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] Overhead cable (full name overhead insulated cable) is an overhead wire equipped with an insulating layer and a protectiv...
