Problems solved by technology

[0004] In the prior art, the outer surface of the cable is usually set to black, so when it is hung outdoors for a long time, it will accelerate the cracking and aging of the surface due to the long-term absorption of the sun's heat radiation, thereby reducing its service life and prone to power failure.

Embodiment 1

[0045] see Figure 1-4 , an outdoor cable based on phase-change heat radiation reflection, comprising an outdoor cable body 1, the outer end of the outdoor cable body 1 is provided with a plurality of evenly distributed outer heat-changing traction rings 2, and the outer end of the outdoor cable body 1 is fixedly connected to a The buffer outer cladding 3 on the inner side of the outer heat-variable traction ring 2 has a plurality of uniformly distributed built-in pneumatic cavities 4 dug inside the outer heat-variable traction ring 2, and the built-in pneumatic cavities 4 are filled with rubber capsule balls 5, each adjacent A connecting pressure rod 6 is fixedly connected between the two rubber encapsulated balls 5, and a traction magnetic ball 7 is fixedly connected inside the rubber encapsulated ball 5, and the inside of the rubber encapsulated ball 5 is filled with ammonium chloride powder 8. The inner ring wall of the ring 2 is dug with a plurality of evenly distributed ...

Abstract

The invention discloses an outdoor cable based on phase-change thermal radiation reflection, and belongs to the technical field of power equipment. According to the scheme, an outdoor cable body is illuminated by light, so that thermal decomposition of ammonium chloride powder in a rubber encapsulated ball in an illuminated area can be promoted, and the air pressure in the rubber encapsulated ballis increased. The magnetic shielding state of traction magnetic balls is removed by means of expansion of the rubber encapsulated ball, and the outdoor cable body can be deformed to be elliptical bymeans of attraction between the adjacent traction magnetic balls and extrusion of an upper connecting pressing rod, so that on one hand, the illuminated area of the outdoor cable body can be reduced,and the amount of heat radiation absorbed by the outdoor cable body is reduced, and on the other hand, air in a built-in pneumatic cavity can be extruded out by means of deformation of the rubber encapsulated ball, eject open a rubber sealing sheet and then is released outwards by means of airflow exchange holes, and therefore the outdoor cable body on the outer side is blown, and the cooling effect on the outdoor cable body is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment, and more specifically, relates to an outdoor cable based on phase-change heat radiation reflection. Background technique [0002] A cable is made of one or more mutually insulated conductors and an outer insulating layer, and is used to transmit power or information from one place to another, usually consisting of several or groups of conductors (at least two in each group) ) twisted rope-like cable, each group of conductors is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. Cables have the characteristics of internal electrification and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, and aluminum alloy cables. etc. They are ...
