Product overview:
DFW 10kV cable branch box is a cable engineering equipment widely used in the power distribution network system in recent years. Its main characteristics are two-way door opening and using butt sleeve as the connection busbar, and it has significant advantages such as small length, clear cable arrangement, and three core cables do not need large span crossing. The cable joints adopted comply with DIN476 36 standard. Generally, bolts with rated current of 630A are used to fix connecting cable joints.产品型号说明
