Overview

Medium- and high-voltage equipment forms the backbone of every substation and industrial network. We coordinate the selection of switchgear panels, circuit breakers, disconnectors, instrument transformers and surge arresters with the manufacturer’s engineering team so that ratings, protection schemes and interfaces match the customer’s design.

Typical scope

  • Metal-clad and metal-enclosed MV switchgear, air- or gas-insulated
  • Ring main units for secondary distribution
  • HV circuit breakers, disconnectors and earthing switches
  • Current and voltage transformers, surge arresters
  • Protection relays, bay control units and communication interfaces

Engineering coordination

For consultants and EPC contractors we can support single-line diagram reviews, panel layouts, interlocking logic and protection setting discussions with the manufacturer. Interface documents are provided in English; Slovak and other languages on request.

Voltage levels, ratings and technologies shown are typical and must be confirmed by the manufacturer per project. SF6-free options and European test certificates are to be confirmed for each product line.

Typical applications

  • Primary and secondary distribution substations
  • Industrial MV networks and ring main units
  • Grid connection points for renewable plants
  • HV switchyards and transmission substations

Key parameters

Parameters shown are typical ranges to be confirmed by the manufacturer for each specific project.
