Problems solved by technology

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

Embodiment 1

[0044] see Figure 1-5 , a phase-change heat radiation absorption type outdoor cable, including a wire and cable 1, a plurality of evenly distributed magnetic powders are fixedly connected in the outer rubber skin of the wire and cable 1, thereby attracting the moving magnetic ball 4 to promote the arc-shaped light-shielding bag The moving end of the sheet 3 is always attached to the surface of the electric wire and cable 1, and the outer end of the electric wire and cable 1 is fixedly connected with a plurality of evenly distributed outward-looking light rings 2, and the outer-like light ring 2 includes a plurality of evenly distributed and fixedly connected arcs with the electric wire and cable 1. Shaped light-shielding capsule 3, the arc-shaped light-shielding capsule 3 is fixedly connected with a moving magnetic ball 4 and a fixed magnetic ball 5, and the moving magnetic ball 4 and the fixed magnetic ball 5 are respectively located on both sides of the arc-shaped light-shie...

Abstract

The invention discloses a phase-change thermal radiation absorption and storage type outdoor cable, belongs to the technical field of cables, and aims to promote ammonium chloride powder in an arc-shaped shading bag sheet to be heated and decomposed through irradiation of sunlight on the arc-shaped shading bag sheet, so that the air pressure in the arc-shaped shading bag sheet is increased, and the arc-shaped shading bag sheet extends outwards to wrap the surface of the cable. On one hand, the contact area between light and the surfaces of the wires and the cables can be reduced, and on the other hand, the ammonium chloride powder in the arc-shaped shading bag pieces can be used for replacing the wires and the cables to absorb heat radiation by means of the heat absorption effect of the ammonium chloride powder, further, the possibility of premature aging of the wire and cable is reduced, the service life of the wire and cable is prolonged, the high-temperature phase state of the wireand cable is recovered after the temperature of the traction metal rope rises, a light reflection ball in a spherical storage groove is driven to be exposed, and the heat radiation quantity received by the wire and cable can be reduced by means of the reflection effect of the light reflection ball on light.

Description

technical field [0001] The invention relates to the technical field of cables, and more specifically relates to a phase-change heat radiation absorption type outdoor cable. 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 all composed of...
