  General

     The product is assembled by the welded bending steel plate through the bolts; the whole cabinet includes the fixed shell and handcart with wheels. There is handcart room, bus room, cable room and relay instrument room separated by steel plated and insulating plate. The shell protection is IP2X which is high parameter, high system and reasonable structure.

    The top part of positive cabinet is the relay and instrument cubicle, and the handcart room and the pressure release channel is under the door. The observation window is on the door, the secondary cable incoming is on the left bottom. The main bus room is on the top of the back of the cubicle, and the cable-room is on the end. The observation window is installed on the back closure panel, and there is no interlocking on the lower closure plate and the earth switch, the instrument plate can be equipped with the live display devices. The top closure panel can not be demounted when the bus is charged.

    The hand-car is formed by bending welded steel plate, and the end is installed with four steels, ground contact-oriented devices, and pedal lock mechanism, and handcart lever feed mechanism. The handcart is easy to be operated. The handcart is classified as circuit breaker handcart, voltage transformer handcart, current transformer, arrester handcart, capacitor, lighting arrester handcart, transformer handcart, isolation handcart and grounding handcart.
