Product Details

TNNPI IEC metal-clad withdrawable MV switchgear is designed for reliable medium-voltage power distribution, switching and protection. Available in 12kV, 24kV and 40.5kV configurations, the panel integrates a withdrawable vacuum circuit breaker, busbar compartment, cable compartment, CT/PT and protection control system. KYN28A and KYN61 configurations can be engineered for different voltage classes and project requirements. The withdrawable VCB design supports service, test and isolated positions, simplifying inspection and maintenance. Panel dimensions, busbar arrangement, protection relay, cable entry and electrical components can be customized according to customer SLDs and IEC requirements.

Applications

Suitable for substations, utility power grids, industrial plants, mining projects, commercial infrastructure, renewable energy facilities and large power distribution systems. The 12kV/24kV configuration is suitable for medium-voltage distribution networks, transformer feeders and industrial power systems, while the 40.5kV class is suitable for higher-voltage substations and grid distribution. KYN28A and KYN61 panels can be arranged as incoming feeders, outgoing feeders, transformer protection, bus couplers and metering panels to create complete MV switchgear lineups.

Core Technical Parameters

  • Rated Voltage: 12kV / 24kV / 40.5kV
  • Rated Current: Up to 3150A
  • Circuit Breaker: Withdrawable Vacuum Circuit Breaker (VCB)
  • Rated Frequency: 50/60Hz
  • Short-Circuit Breaking Current: Up to 31.5kA
  • Standard: IEC 62271-200 / IEC 62271 series
