These high-protection, high-current shielded circular connectors feature resistance to extreme temperatures, shock, and water, as well as insulation and flame-retardant properties. They are widely used in photovoltaic inverters, energy storage battery packs, the “three-electric” systems of new energy vehicles, wind turbine pitch control units, and charging station equipment. They enable high-voltage power transmission, BMS signal acquisition, and communication interconnectivity, while withstanding outdoor conditions such as wind, sand, and rain, as well as continuous equipment vibration. This ensures the safety of power supply and the stability of data monitoring for new energy equipment.
