DFW the American Cable branch box is mainly characterized by one-way door opening and horizontal multi-pass busbar, and has the advantages of small width, flexible combination, full insulation and full sealing. According to the rated current, it can be generally divided into 600A main circuit and 200A branch circuit. The 600A main circuit adopts screw-in bolted connection; the 200A branch circuit adopts plug-in connection and can be plugged and plugged under load.
If the cable junction box cannot be placed due to the limitation of the site, the cable joints can be directly combined to form a multi-channel cable branch (the busbar is not required, the connection method is shown in the following example) and placed in the cable trench or other locations. Example 1 Four-way incoming and outgoing lines (2x600A+2x200A)
