The SMC cable distribution box body is made of SMC composite material (sheet molding compound) and is molded in one step at high temperature. It has light specific gravity, mat corrosion resistance, aging resistance, good sealing performance, beautiful appearance, and all-weather protection function. It can meet the needs of various harsh environments and places in outdoor engineering projects, and overcomes the shortcomings of outdoor metal cable branch boxes that are easy to rust, have a short lifespan, and have poor thermal insulation performance. It is widely used in three-phase low-voltage power transmission and distribution systems in outdoor public places such as power transformation and distribution stations, public mining enterprises, both sides of streets, garden residential areas, high-rise buildings, airports, key construction and renovation projects, etc., as a complete set of finalized equipment for distributing electric energy to other users or equipment using cables.

Product features
The SMC cable distribution box body is made of SMC composite material (sheet molding compound) and is molded in one step at high temperature. It has light specific gravity, mat corrosion resistance, aging resistance, good sealing performance, beautiful appearance, and all-weather protection function. It can meet the needs of various harsh environments and places in outdoor engineering projects, and overcomes the shortcomings of outdoor metal cable branch boxes that are easy to rust, have a short lifespan, and have poor thermal insulation performance.
Cable branch boxes are mainly characterized by one-way opening doors and horizontal multi-pass busbars. They have significant advantages such as small width, flexible combination, full insulation, and full sealing. According to the classification of carrying capacity, it can generally be divided into two types: 630A main circuit and 200A branch circuit. Its connection and combination method is simple, convenient and flexible.
