Medium Voltage Metal-Clad Switchgear
The metal-clad switchgear is an indoor complete distribution device designed for three-phase AC, 50 Hz, 7.2–12 kV single-bus segmented systems. Its core technology is fully sourced from Eaton, ensuring reliable performance. The switchgear is suitable for:
- Power plants
- Urban power supply networks
- Industrial systems
- Commercial buildings
It is primarily used for receiving and distributing electrical energy and provides circuit control, protection, and monitoring functions.
Key Components:
Withdrawable Vacuum Circuit Breaker: Eaton (Westinghouse technology) NVU12 type
Performance Features:
- Fully meets power grid requirements for medium-voltage switchgear
- Supports “five protections” and special conditions:
