Air insulated medium voltage switchgear for secondary distribution, MOD6 range

MOD6 range modular units have been planned to meet the public and industrial power distribution’s requirements.

MOD6 modular units are used for the MV sections in MV/LV transformer substations, in public distribution systems and MV consumer or distribution substations.

The MOD6 range is made up of standard, modular and compact units, and internal arc resistant. The MOD6 switchgear are air insulated modular units, containing SF6 switch-disconnector or vacuum circuit breaker.

Today EnergoBit offers a comprehensive portfolio of medium voltage switchgear according to the requirements of Electrica, ENEL, CEZ, E.ON.

Complex switchboard configurations can be realized using the standard panels.

MOD6 range unit definitions

  • RMb incoming cable-connection unit
  • LM switch unit
  • TM fuse-switch combination unit
  • IMP single-isolation fixed circuit breaker unit
  • IMS single-isolation fixed circuit breaker unit
  • IMPw single-isolation withdrawable circuit breaker unit
  • IMSw single-isolation withdrawable circuit breaker unit
  • CS, CD switch unit right or left outgoing line
  • RMs/RMd connection unit right or left outgoing line
  • MCT current and voltage measurement unit
  • MT voltage measurement unit
  • SI MV/LV transformer unit for auxiliaries
  • LLM cables power supply for main incoming line and standby line

The main characteristic of MOD6 range cells is modularity, which allow us to realize complex and custom solutions.

MOD6 range cells represent the most efficient solution possible to be implemented which, in the same time, leaves opened options for future evolution.
