1. AC Power Distribution Switchgear 40.5kv 33kv High Voltage
Power Distribution Switchgear is a device connected to high voltage or low voltage cable. General power supply bureaus and substations use high-voltage cabinets, and thru the power transformer for step down to low-voltage cabinets, then thru low-voltage cabinets to each power distribution box.
2. Features
- Various switch operation can be carried out with high voltage
compartment doors closed.
- The switchgear is totally metal-clad and enclosed. The
protection degree of enclosure is IP4X to ensure personal
safety.
