Metal Clad Switchgear
Item No.: | XGN37-12 |

⊙Standard scheme of cable inlet and outlet and its interconnection cabinet: W840×D1300×H 2300.
⊙Overhead inlet and outlet wire cabinet: W840×D (1300+400)×H2300.
⊙When the transformer capacity exceeds 30Kwa, the cabinet width is 1000.
⊙The breaker can be of side-mounted type, and its outline dimension is W800×D1000×H2300.
Note: the cabinet depth excludes the dimension of the front door and rear seal plate, and the ph-ph distance is 210.
1. The enclosure is made of imported aluminum-plated zinc sheets with strong corrosion and oxidation resistance and good looking.
2. The cabinet body is of modular type structure, which is connected with high-strength bolts. The overall cabinet has high precision and mechanical strength. With individually design meter compartment and busbar compartment, it can shorten the processing and production cycle and facilitate the production organization.
3. The component layout in the switchgear is compact, and the outline dimension of the cabinet is small. The main switches in the cabinet can adopt fully insulated VS1 vacuum circuit breaker, so as to reduce maintenance.
4. The protection class of the enclosure is IP4X, and it is IP3X while the door is opened. The distance to the ground for the charged body is not less than 125mm.
5. The lower isolating switches and earthing switches are flexibly arranged. The cabinet body can be either installed against the wall for front maintenance or installed off the wall for double-side maintenance.
