Medium-voltage switchgear

VacClad-HD 38 kV metal-clad medium voltage switchgear

Eaton’s VacClad-HD switchgear is a metal-clad medium-voltage solution that can be custom-engineered to fit a wide array of application and safety requirements. This versatile 38 kV medium-voltage switchgear can be assembled in various combinations to meet specific usage requirements. It’s a trusted choice for applications such as control and distribution, main-main automatic transfer, main-tie-main automatic transfer, main service disconnect, switching, and more.

VOLTAGE CLASS
up to 38 kV
CONTINUOUS CURRENT
up to 3000 A
INTERRUPT RATING
up to 40 kAIC
  • Utilizes the medium-voltage VCPW-HD vacuum interrupter circuit breaker
  • Compartmentalized metal-clad design
  • Insulated bus conductors and connections
  • Automatic shutters that open and close with breaker racking position
  • Auxiliary drawer over breaker configurations
  • Closed door racking
spacer
  • Coordination with Medium-Voltage Transformers, and Medium-Voltage Non-Segregated Bus
  • Ohmic Voltage Sensing (OVS) to replace traditional Voltage Transformers (VTs) for improved reliability and safety as OVS is not susceptible to switching transients and requires no maintenance
  • Integral Motorized Remote Racking (MR2) for circuit breakers and auxiliary drawers
  • Eaton's partial discharge monitoring solution Insulgard can be integrated including the required coupling capacitor for online partial discharge monitoring
  • Proven continuous thermal monitoring solution through Exertherm sensors installed in a tested configuration for accurate and consistent readings
  • Meter and relay integration including Eaton's EDRPXE, and PXQ  families
  • Automatic transfer schemes for main-tie-main or other configurations
  • Infrared viewing windows for manual connection monitoring
  • Roll-on-the floor breakers
spacer
  • IEEE C37.20.2 Medium-Voltage Metal-Clad Standard 
  • CSA C22.2 No. 31 Switchgear Assemblies 
  • UL and CSA third party certification and labeling optional 
  • IBC/CBC seismic labeling and design optional
  • OSHPD seismic labeling and design optional
