Photovoltaic systems are exposed to large open spaces, often in the wild or on top of buildings, and charged rain clouds that accumulate over such open spaces tend to release their charge in the form of lightning. When a surge current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. The upstream raw material suppliers of the photovoltaic surge protector industry chain mainly provide various raw materials and components required for surge protectors; the manufacturing of midstream surge protectors is the core link of the surge protector industry chain; the downstream application fields are electrical The ultimate beneficiary of the surge protector industry chain. In terms of technology research and development capabilities, China has strong capabilities in the research and development of photovoltaic surge protectors. Many domestic companies have invested a lot of money in technology research and development and obtained many patents; in terms of product quality, China's photovoltaic surge protectors quality of surge protector products are improving year by year. China's photovoltaic surge protector industry has achieved certain results in technological development, which are mainly reflected in three aspects: technological innovation, intelligence, and standardization. Overall, the technological development level of China's photovoltaic surge protector industry is at a relatively high level. High level, expected to continue to maintain its leading position in the future. In the future, photovoltaic surge protector industry technology will develop in the direction of safety, integration, intelligence, energy conservation, and environmental protection. Jinli Electric has always maintained the spirit of industry self-discipline, constantly innovated, and introduced new technologies to comprehensively improve the quality of lightning protection products. Thereby adapting to the ever-evolving needs of the lightning protection market. The new series of photovoltaic products developed by it are successively launched on the market, such as JLSP-GD 1000/40 and other models. The system is widely used in wind power and photovoltaic and has won the recognition and trust of many customers. Jinli Electric not only promotes the healthy development of the surge protector (SPD) industry but also plays an active role in ensuring public safety in lightning protection.
