DSY-DFW-12/24 European cable distribution box

Overview:

European-style cable distribution box is a cable-based engineering equipment widely used in power distribution network systems in recent years.
Its main features are two-way door opening, using wall bushings as connecting busbars, small length,
The cables are clearly arranged and the three-core cables do not require large-span crossovers. The electricity it uses
Cable glands comply with DIN47636 standard. Generally, bolted connection type with rated current 630A is used.
Cable connector.
