The metal cable junction box body is mainly made of stainless steel material (304) or cold-rolled steel plate processing and forming. It has anti mat corrosion, good sealing performance, aesthetics, and all-weather protection function, which can meet the needs of various harsh environments and places in outdoor engineering projects. It is widely used in three-phase low-voltage transmission and distribution systems in outdoor public places such as transformer substations, public mining enterprises, street sides, garden residential communities, high-rise buildings, airports, and key construction and renovation projects. It serves as a complete set of standardized equipment for distributing electricity to other users or equipment through cables.
