The main technical parameters

Structural features

Cabinet structure

· Ring enclosure with thick deposited aluminum zinc plate (or cold-rolled plate spray after) riveting molding, cabinets equipped with pressure relief hole after two, one is for the cable room, another for load switch / wire room mother. This structure can guarantee the maximum extent physical installation and reliable operation of the equipment.

· Each interval chambers

· Bus Room: Located on top of the cabinet and connect adjacent busbar switchgear.

· Load switch is a standalone unit, interior filled with SF6 gas.

· Cable room: about 75% of space is used for cable connections, fuses, earthing switches and CT, PT installation.

· Small room with interlocking institutions: small room that contains the operating agencies and institutions as well as interlocking position indicator, auxiliary contacts, tripping coil, live display and interlocks.

? Relay Box: relay box at the top of the cabinet, is optional. Little room to install a special device such as meters, relays and motor unit.

· Circuit breaker compartment: a circuit breaker can be placed underneath the load switch.

Pressure release

· The above pressure release: the above is for the release of gas pressure generated when the bus and load switch room inside the arc accident.

· The following pressure release: The following is a release of gas pressure generated when the cable compartment internal arc accident.
