Integrated Substation Solution

Integrated Substation Solution

TOONICE prefabricated substations integrate medium-voltage switchgear, transformers, low-voltage switchgear and auxiliary systems into a factory-assembled enclosure.

The substation can be configured for utility, industrial, infrastructure and renewable-energy projects, with equipment selection, protection, metering and enclosure design adapted to project requirements.

Depending on project requirements, the solution can be configured as a compact transformer substation, box-type substation or other project-specific prefabricated arrangement.

  • MV Switchgear
  • Power Transformer
  • LV Switchgear
  • Protection and Metering Systems

Typical Configurations

  • 01

    MV + Transformer + LV
