PASS M0 is the line of the PASS product family which covers voltages from 110 kV to 170 kV and amperages up to 50 kA; it is the most widespread PASS module, with more than 6500 installations all around the world.
It is available in three configurations:
- Single Bus Bar (SBB)
- Double Bus Bar (DBB)
- Double Circuit Breaker (DCB)
And two versions:
- Classic
- Rotating Chamber
Technology
The PASS family of switchgear modules takes advantage of a Hybrid technology solution: on the one side it uses reliable Air Insulated connections between modules; on the other side it encloses the bay functions in a single phase Gas Insulated housing, fully-comprehensive of:
- Circuit breakers
- Disconnector
- Earthing switches (fast or slow)
- Voltage transformers and Voltage sensors
- Current Transformers
- Bushings or Cable enclosures
Advantages
- High customizability yet short delivery time, due to the modular design of PASS modules and the implementation of Just In Time - Assemble To Order production models
- High reliability, due to the use of standard components continually reduced in number
- Few installation space requirements, due to the completeness of functions enclosed in one single PASS module
- Fast erection and commissioning, due to the fully-assembled configuration of the modules during transport
- Life cycle cost significantly lower than AIS or GIS technologies
