| GG-1A-12Z Fixed Voltage Switchgear |
| Application | |
| GG 1 1A 1 12Z Fixed Voltage Switchgear suitable for 3 6 ~ 12kV
voltage level, single busbar and single busbar section the main
wiring grid electric field, industrial and mining enterprises,
docks, oil fields, Feng Road, residential quarters and other users
high-voltage substation as electricity and fed by and large motor
control and protective, as the Company of a 1A in the original GG
switchgear on the basis of the type switch cabinet to the "Five
Anti", "no oil," and intelligent transformation, so that the type
switch cabinet is more suitable for reconstruction and upgrading of
the old substation. |

| Structural characteristics | |
| GG 1 1A 1 12Z fixed line switchboard open structure, the basic
frame and plate bending by the angle iron welded together, at the
beginning of the main cabinet and the cabinet cover the whole field
by the cabinet formed part of the main cabinet is divided into two
bus divisions , the upper for the bus and isolation switch,
grounding switch, the middle circuit breakers, transformers, the
lower chamber for the cable outlet. Front left room for the relay,
the lower part of the terminal room, this cabinet a perfect
"five-anti" blocking function. |
