Compact substation

The Compact Substation is a connection-ready cabin, designed for secondary power distribution in industrial applications and in the oil & gas sector. It is a robust, factory-integrated metallic enclosure, engineered to ensure high safety, compact configuration, and fast installation, and designed to operate even in remote or harsh environments.

Key components include:
  • Gas-insulated (GIS) medium-voltage switchgear (up to 40.5 kV)
  • Low-voltage switchboard
  • Protection relays and automation system
  • Auxiliary systems and internal climate control
  • Active fire suppression system, typically based on gas-extinguishing technologies
  • Power Distribution Tranformers or auxiliary transformer
Our range of compact substations includes:

STC-BOX

It is a complete, pre-configured and ready to install substation.

OIL TRANSFORMER – SKID SOLUTION

The skid solution is a prefabricated installation-ready compact substation, designed to elevate energy from PV plants to elevating substations. It is equipped with Oil-type transformer - up to 10000kVA

DRY-TYPE TRANSFORMER – KIOSK SOLUTION

The Kiosk solution is a prefabricated plug-in compact substation, equipped with power distribution components, including Dry-type transformer - up to 5000kVA Our Compact Substations come fully pre-wired and installation-ready, minimizing on-site operations and ensuring efficient commissioning. The remote control system optionally integrated ensures higher efficiency and safety.

Technical features
  • The body structure (base, uprights, supports, roof) is made of steel sheets with a thickness of 25-30/10mm, Sendzimir SZ275 type, galvanized and coated with epoxy resin, suitable for outdoor installations in hostile environments

  • It can be supplied as a centralized inverter or as a string inverter.

  • Transportation methods: It can be lifted from lifting brackets and placed by a crane on the concrete foundation.

  • Alternatively, it can be dragged by a tractor. Dragging is done by attaching the steel holding lines with hooks to the ends of the cabin, where the anchoring points are.

Advantages
  • Connection-ready

  • Customized internal configurations

  • Compact and small size structure

  • Suitable for road and sea transportation

  • Resistant to elements and hostile environmental conditions

Applications
  • Oil and gas

  • Secondary power distribution grid

  • Industrial applications
