Features

     The casing consists of porcelain, metal fittings, mounting flanges and conductive rows (rods).

Use and classification

     Wall-walled porcelain bushings are used in power station and substation power distribution units and

high-voltage electrical appliances for wires to pass through grounded baffles, walls or electrical equipment

enclosures, supporting conductive parts to insulate them from the ground or the enclosure.
     Wall-walled porcelain casings can be divided into indoor and outdoor wall-through porcelain casings

according to their use environment. According to the different conductors passing through the center, it

can be divided into busbar through-wall porcelain bushings, copper conductor through-wall porcelain

bushings and aluminum conductor through-wall porcelain bushings.
     When the copper conductor is directly connected to the busbar, it is easy to produce galvanic corrosion.

If the contact surface temperature rises too high, the joint will burn out and affect the life of the equipment.

Therefore, the copper-aluminum transition joint should be used, but it will bring trouble to the construction

on site. The casing solves the above problem.
     The indoor and outdoor wall-walled porcelain casings are assembled from porcelain parts, conductive

rods, metal fittings at both ends and mounting flanges. The busbar through-wall porcelain bushing is

assembled from porcelain, metal fittings at both ends, busbar splint and mounting flange.
