The 630A integrated bushing provides convenience for the connection of the switch cable branch box and the ring network cabinet. The 630A integrated bushing with umbrella skirt is connected to the copper bar to achieve air insulation; the other side is installed with a 630A European-style front connector to achieve insulation and full sealing .

Wall bushings are widely used in European cable branch boxes and ring network switch cabinets to make the structure more reasonable and scientific.

The four Φ11 screw holes in the middle part of the wall bushing are fixed holes, and the two M4 screw holes on the side provide current signals for the three-phase centralized live display, making the structure more compact and more convenient to use. Both ends of the casing are equipped with 630A European-style front connectors, and the branches can be expanded to realize multi-branch power supply; when the casing is not live or branched, 630A insulating caps can be installed on the casing to seal it to provide dust-proof and moisture-proof insulation protection.
