Description

Cable distribution boxes are equipment widely used in the cabling projects of power distribution systems in recent years. They are extensively applied in power grid projects in various places such as industrial parks, residential communities, densely populated urban areas, commercial centers, and high-rise buildings.

The main features of Mohu European-style cable branch boxes are two-way opening doors, using butt sleeves as connecting busbars, with significant advantages such as short length, clear cable arrangement, and no need for large-span crossing of three-core cables. The cable joints used in it comply with the DIN47636 standard. Generally, bolt-fixed cable joints with a rated current of 630A are adopted.

Mohu American-style cable branch boxes are mainly characterized by one-way opening doors and horizontal multi-way busbars, with significant advantages such as small width, flexible combination, full insulation, and full sealing. According to the rated current, they can generally be divided into two types: a 600A main circuit and a 200A branch circuit. The 600A main circuit adopts screw-in bolt-fixed connection, and the 200A branch circuit adopts plug-in connection and can be plugged and unplugged under load.
