European cable split-box is widely used in power distribution network in recent years in the cable engineering equipment, its main characteristics are two-way door, the use of wall bushing as a connection busbar, with a small length, clear cable arrangement, three-core cable does not need large span cross and other signifi cant advantages. The cable connector used conforms to DIN47636 standard. Generally use rated current 630A bolted bolted connection type cable joint.
