A high temperature resistant photovoltaic cable suitable for salt spray environment

Abstract

The invention discloses a high-temperature-resistant photovoltaic cable suitable for salt spray environment, which includes a cable body, the cable body includes a cable core and a cable sheath, and the special-shaped bracket is composed of two staggered "S"-shaped fixed brackets. The arcs at the two ends of each fixing bracket are embedded with wires, and between the arcs at the top of the two fixing brackets, there are optical fiber units that are attached to the tops of the two adjacent wires. There are two lifting bodies at the intersection of the fixed bracket, and the cable sheath includes a wear-resistant layer, a heat-conducting layer, a hydrophobic layer and an outer sheath in sequence from the inside and outside, and a metal mesh is arranged between the wear-resistant layer and the heat-conducting layer , the wear-resistant layer is provided with a heat dissipation mechanism, the heat dissipation mechanism includes a heat dissipation groove set on the wear-resistant layer, a lifting rod fixed on the top of the lifting body, and a gasket that is compatible with the heat dissipation groove. The present invention not only has a higher Compressive performance, under the action of external impact force, the heat dissipation effect can be accelerated through the heat dissipation mechanism.

Description

Technical field [0001] The present invention relates to the field of photovoltaic cable technologies, and is specifically a high temperature resistant photovoltaic cable suitable for a salt spray environment. Background technique [0002] Anti-salt fog photovoltaic cable is a power connection assembly for marine photovoltaic power generation. The cable is floating on the sea, and the power is transmitted to the mining equipment. In such cases, it is often necessary to suffer from severely corruption of strong ultraviolet irradiation, high salt stain, etc., but also the blow of wind and waves, so sea The compressive performance of the cable needs to be further improved, and the heat dissipation effect of the existing anti-salt fog photovoltaic cable is poor, and it is not possible to rapidly cool down, which will reduce the carrier flow of the cable, which affects the stability of the cable. Inventive content [0003] It is an object of the present invention to provide a high tem...

Problems solved by technology

Cables float on the sea surface through buoys, and transmit power to mining equipment. In such applications, they often have to withstand severe corrosion such as strong ultraviolet radiation and high salt pollution, as well as blowing by high wind speed and sea waves. Therefore, offshore The compressive performance of the cable needs to be further improved, and the existing anti-salt spray photovoltaic cable has a poor heat dissipation effect, and cannot be cooled quickly, which will reduce the current carrying capacity of the cable, thereby affecting the stability of the cable.
