Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic power generation, in particular to a cable retracting and releasing device for solar photovoltaic power generation. Background Art

[0002] Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is increasingly widely used in China. The characteristics of photovoltaic cables are determined by their special cable insulation and sheath materials, which we call cross-linked PE. After irradiation by the irradiation accelerator, the molecular structure of the cable material will change, thereby providing its various performances and resistance to mechanical loads. In fact, during installation and maintenance, the cable can be routed on the sharp edge of the roof structure. At the same time, the cable must withstand pressure, bending, tension, cross-tension loads and strong impacts. If the cable sheath is not strong enough, the cable insulation layer will be severely damaged, which will affect the service life of the entire cable, or cause short circuits, fires and personal injury risks.
