Product Features:
❖ The main busbar connection method allows for easier expansion of switchgear. The busbar in a single cabinet is independent and uses a busbar arrangement for connection. This design facilitates on-site installation and makes it easier to add switchgear for capacity expansion.
❖ Space-saving with high installation density, providing an optimized solution for compact distribution room spaces. It reduces the floor area occupied by the distribution room, allowing more cabinets to be installed in the same space.
❖ Various drawer sizes available, allowing for tailored options as needed. The optimized internal space of the drawers accommodates more secondary components. The three-position design clearly prevents misoperation.
❖ Excellent functional separation ensures safety for both personnel and equipment.
❖ Optional configurations with intelligent systems, supporting RS485 interfaces and standard protocol technologies for remote monitoring, measurement, and control. This enables automated remote management of unmanned substations.
Compliant Standards:
❖ IEC61439.1
❖ IEC61641 and GB7251.1-2013
❖ GB/T14048.1
