Description

Technical Field

[0001] The utility model relates to a cable, in particular to a composite solar mirror field photovoltaic cable. Background Art

[0002] Solar photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are composed of solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Simple photovoltaic cells can provide energy for watches and computers, while more complex photovoltaic systems can provide lighting for houses, traffic lights and monitoring systems, and be connected to the power grid. Photovoltaic panels can be made into different shapes, and the components can be connected to generate more electricity. Photovoltaic panels can be used on rooftops and building surfaces, and can even be used as part of windows, skylights or shading devices. These photovoltaic facilities are usually called building-attached photovoltaic systems.

[0003] According to market research and the current status of cables used in solar photovoltaic power plants in desert areas, most commonly used photovoltaic cables are single-core cables without sheaths. It is troublesome to lay multiple wires, and there is no radiation-proof outer sheath. The cables are easily aged due to high temperature and cold weather. In addition, a signal cable must be laid separately, and the laying cost is relatively high. Utility Model Content
