Product Definition
European cable distribution box is widely used in recent years in the power distribution network system of the cable engineering equipment its main features are two-way door, the use of docking sleeve as a connecting busbar, with a small length. The cable arrangement is clear, the three-core cable does not need a large span cross and other significant advantages. The cable joints used meet DIN47636 standards. Generally, the rated current 630A bolt fixed connection type cable joint.
