Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic cables, and in particular relates to a cable that can be installed on a photovoltaic panel bracket. Background Art

[0002] Photovoltaic cable is a special cable designed for photovoltaic power generation system. It has the characteristics of high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV resistance, flame retardancy, environmental protection, long service life, etc. It is suitable for harsh climatic conditions. In actual use, most photovoltaic cables are installed on photovoltaic panel brackets, so that the photovoltaic cables are routed along the photovoltaic panel brackets and fixed. Most photovoltaic panel brackets are made of metal materials. The actual installation requires cutting and splicing of photovoltaic panel bracket materials according to the on-site conditions. The corners of the brackets after cutting are mostly sharp structures and have certain burrs. These sharp parts and burrs are not processed during the installation process, making it difficult to effectively protect the cables when encountering these places during the installation process.

[0003] Especially these sharp parts and burrs are at the end of the bracket. The photovoltaic cables need to be bent and routed in these areas, which will cause more damage to the photovoltaic cables. The photovoltaic cables may be cut during the pulling process of routing. These cut parts are at the lower end of the outer side of the cable, which is difficult for the installers to find. As a result, the subsequent use of the cables will be difficult to sustain, and the subsequent maintenance difficulty will be increased.

[0004] In summary, due to problems existing in the actual installation of photovoltaic cables, photovoltaic cables may be cut, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
