DFW-12 DFW-24 630A European common high voltage outdoor cable branch box
Overview
European-style cable distribution box is a cable engineering equipment widely used in power distribution network systems in recent years. Its main features are two-way door opening, wall bushings as connection busbars, small length, clear cable arrangement, and three-core The cable does not require significant advantages such as large span crossover. The cable connector used complies with the DIN47636 standard. Generally, a fixed connection type cable connector with a rated current of 630A is used.
