Medium Voltage Switchgear

Medium Voltage Switchgear


(1) Semi-enclosed medium voltage switchgear. the front and side of the cabinet are closed, the back and busbar are bare, the structure is simple, the cost is low, the safety is poor, and it is close to elimination, such as GGlA type.

(2) Box type medium voltage switchgear with metal casing. But the number of intervals is small, the busbar is also closed, and the safety is better. Such as XGN type.

(3) Interval type medium voltage switchgear. Each room is separated by one or more non-metal separators, and the safety type is better. Such as JYN type.

(4) The armored medium voltage switchgear is separated and grounded by metal partitions between the rooms. It has good safety, complex structure, high processing precision and slightly higher price. Such as the domestic KYN type, ABB's ZSl type.
