Industrial sockets and plugs are mainly used in Marine machinery for deck equipment power supply, engine room power transmission and Marine control system connection, and need to adapt to the harsh environment of high salt spray, humidity and vibration. It is designed to comply with classification society certification standards (such as CCS, DNV), with IP56 and above protection, corrosion resistant materials (such as stainless steel or nickel-plated housing) and explosion-proof properties to ensure long-term stable operation in the Marine environment. Some products adopt waterproof quick-plug, anti-loose structure, and support high current (440V/60Hz or more) transmission to meet the special needs of Marine equipment for safety, weather resistance and shock resistance.
