Product Summary
DFW10-12 outdoor AC cable branch box is a cable engineering equipment widely used in power distribution system. Its main features are two-way door opening and using butt bushing as connection bus-bar. It has remarkable advantages such as small length, clear cable arrangement and no need for large span crossing of three-core cable. The cable connectors are in accordance with the DIN47636 standard.
The rated current 630A bolt fixed connection type cable joint is generally adopted.
Structural Features
1、Full insulation, fully sealed structure, full protection, full working conditions;
2、Flexible entry and exit, the actual application of the most branches and exports of eight branches;
3、Anti frost, anti condensation;
4、With semi conductive shielding layer of silicone rubber cable connector, to ensure personal safety;
5、The realization of district multi-channel transmission.
6、The cable head is touch type.
