If the above conditions cannot be met, users should specify additional requirements when placing orders.

1. Main circuit scheme number, purpose, single-line system diagram, arrangement diagram, and layout plan of the distribution room.
2. Auxiliary circuit wiring diagram, terminal arrangement diagram.
3. Model, specifications, and quantity of electrical components inside the switchgear.
4. Requirements for control, measurement, and protection functions of the switchgear, as well as other interlocking and automatic devices.
5. If busbar bridging connections are needed between switchgear or incoming cabinets, provide specific requirements such as the rated current, span, height above ground, etc.
6. Specify types and quantities of accessories and spare parts.
7. If the switchgear is used in special environmental conditions, provide detailed information when placing the order.

①For cabinets with glass doors，the minimum depth is 725.
②To facilitate the laying of horizontal busbars，the depth of cabinets in the same arrangement should be uniform.If not uniform，a 400mm wide busbar transfer cabinet should be added at each connection
③Cabinets with busbar bridges or busbar ducts for incoming and outgoing lines should have a depth 2800.
Special requirements for products can be consulted with the manufacturer.
