DFW-12kV European cable junction box

DFW-12 High Voltage Cable Branch Box

DFW-24 630A European common high voltage outdoor cable branch box

Ⅰ.Overview

The cable branch box is only used as the cable branch. The main function of the cable branch box is to tap or transfer the cable, which mainly plays the role of cable tap and cable transfer.

DFW outdoor cable branch boxes are suitable for AC, 50 Hz, 12 kV rated voltage, cable inlet & outlet lines outdoor power distribution networks. They are widely used for industrial parks, residential areas and commercial centers. And they are also used for the power distribution networks of mining, airport, railway, harbor and power station, industrial parks, residential areas and commercial centers. They are especially suitable for urban power network reconstruction projects.
