GZDW High Frequency Switching Current DC Screen
Structural features and number of cabinets
Structural characteristics
1. The front of the cabinet is a full-length glass door, and the back door is a double-door, with a beautiful and large appearance；
2. The cabinet structure design is convenient for equipment installation, commissioning, maintenance, repair and operation；
3.The overall dimensions are 226*800*800*600mm, 2360*800*6020 and other standard specifications；
4.Cabinet color can be customized according to customer needs.
Cabinet quantity
The number of cabinets is related to factors such as modules, number of feeder circuits, battery capacity and model, and DC voltage level.
