Product Description

11kV MV Medium Voltage Switchgear



11kV switchgear is the latest generation of indoor complete power distribution equipment with three phase AC 50Hz or 60Hz, 3.6kV to 12kV single busbar section system. It's mainly used in power plant, substation, industrial and mining factories, as well as high-rise buildings, for power reception and power distribution, with functions of controlling, protecting and detecting electric circuits.

1. Metal-clad and fully enclosed structure, can prevent dirt and small animals from entrance.

2. Each small compartment in the switchgear is separated and independent from each other.

3. Fast closing earthing switch is used for earthing and provides short-circuit current closing capacity.

Switchgear Structure:

1. Switchgear is composed of cubicle and removable parts (so called trolley). The cubicle is separated into several functional compartments by metal sheet, including busbar compartment, circuit breaker compartment, cable compartment and low voltage


2. Switchgear removable parts can be equipped with VCB trolley, voltage transformer trolley, lightning arrester trolley and fuse trolley.


3. Pressure relief devices are installed above trolley compartment, busbar compartment and cable compartment. Special sealing ring on the door seals the panel door.


4. In case of faults inside the compartments resulting in arc, the pressure is going up inside the switchgear and the pressure relief equipped on the top will open automatically, to release pressure and high temperature gas. In this way, it can ensure the safety of operating staff and the switchgear.
