Amid intensifying competition in the photovoltaic industry, connectors act as the "capillaries" of power plants, where the reliability of their engineering plastics directly impacts the safe operation of the entire system. Harsh environments such as prolonged outdoor exposure, extreme temperature fluctuations, and chemical corrosion continuously test the durability limits of connector materials. Zhejiang Chint Xinhui's HCC40 PV connector is designed to address these challenges.
Developed by Zhejiang Chint Xinhui Solar Co., Ltd., the HCC40 PV connector breaks the industry's reliance on new engineering plastics from international chemical giants, successfully resolving the pain point of "insufficient reliability in PV connector material application." The product features a triple-insulation design (annular groove structure, seal fin structure, and internal sheath) to enhance electrical safety and reliability. It also offers excellent compatibility, enabling quick mating with mainstream products like MC4, and is suitable for PV module systems across all scenarios.
Robust Performance for Harsh Environments
