DFW-12 High-Voltage Split Cable Support Box

European-style cable tap-off boxes have been widely used in recent years as cable-based equipment in power distribution networks. Their main features include bi-directional door opening, the use of splice bushings for busbar connections, compact overall length, clear cable arrangement, and the advantage that three-core cables do not require large-span crossings. The cable connectors employed comply with the DIN 47636 standard, typically being bolted-type connectors rated for a current of 630 A.
