Hybrid Switchgear PASS M0S - 420 kV

Compact switchgear assembled and high-voltage tested in factory, for rapid energizing in 24 hours

PASS M0S belongs to the innovative high-voltage hybrid switchgear family PASS (Plug and Switch System). PASS encloses all functions of a complete switchgear bay in a single module. The hybrid design makes use of traditional air-insulated busbars to connect with other equipment in the substation while enclosing the following bay functions in a single-phase gas-insulated housing:

  • Circuit breaker
  • Combined disconnector and earthing switches
  • Voltage transformers and Voltage sensors
  • Current Transformers
  • Motor drive option
  • Fast earthing switch option
  • Plug in cables option

PASS modules are completely factory assembled and tested, ready for rapid installation and energization. This goal is reached by a simple, safe and effective tool to perform the rotation of bushings from service to transportable position, due to a robust sealing interface capable of ensuring tightness during and after rotations.
PASS M0S is available in numerous configurations including single busbar, double busbar, double-circuit breaker, and various other customized configurations are possible.
 

Applications
