High-temperature-resistant photovoltaic cable suitable for salt spray environment

Abstract

The invention discloses a high-temperature-resistant photovoltaic cable suitable for a salt spray environment. The cable comprising a cable body, and the cable body comprises a cable core and a cablesheath. The special-shaped support is composed of two staggered fixed supports of an S-shaped structure. Wires are embedded in the arc-shaped parts of the two end parts of each fixing support; opticalfiber units attached to the tops of the two adjacent wires are arranged between the arc-shaped parts of the tops of the two fixed supports. Two lifting bodies are respectively arranged at the intersection of the two fixed support; the cable sheath sequentially comprises a wear-resistant layer, a heat conduction layer, a hydrophobic layer and an outer protective layer from inside to outside. A metal net-shaped body is arranged between the wear-resistant layer and the heat conduction layer; and a heat dissipation mechanism is arranged in the wear-resisting layer and comprises a heat dissipationgroove formed in the wear-resisting layer, a lifting rod fixed to the top end of the lifting body and a sealing gasket matched with the heat dissipation groove, the cable has high pressure-resistanceperformance, and the heat dissipation effect can be improved through the heat dissipation mechanism under the action of external impact force.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cables, in particular to a high-temperature-resistant photovoltaic cable suitable for salt spray environments. Background technique [0002] Anti-salt fog photovoltaic cable is a power connection component for marine photovoltaic power generation. 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.
