KYN28A / KYN61 HV Metal-Clad Switchgear — Details

Overview

The KYN28A (12kV) and KYN61 (40.5kV) series metal-clad switchgear panels provide reliable high-voltage switching, protection, and control for power distribution systems. Designed with a withdrawable circuit breaker truck for easy maintenance and maximum safety.

Key Features

  • Withdrawable Design: Circuit breaker truck can be safely withdrawn for maintenance without de-energizing the entire switchgear
  • Five-Compartment Construction: Physical segregation of busbar, breaker, cable, CT, and relay compartments
  • Internal Arc Protection: IAC-rated design channels arc energy safely in the event of an internal fault
  • Flexible Configuration: Available as incoming, outgoing, bus-tie, metering, or capacitor compensation panels
  • Intelligent Control: Optional microprocessor-based relay protection and SCADA communication

Applications

  • Power plant switchyards
  • Industrial facility main distribution
  • Utility substation (primary and secondary)
  • Data center critical power switching
  • Railway traction substations
  • Renewable energy plant grid connection
