12kV Pre-installed substation With High Voltage and Low Voltage
House Power Sesterm
Description:
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.
Features:
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.
