03Preliminary sizing

Which substation does your site need

Enter the load and reliability category. You get an indicative transformer size and scope of work, then send it to us for an exact calculation.

Take it from the brief or ask the building’s designer.

Scope of work

    Indicative, at cos φ = 0.9. With two transformers, each is sized to carry the full load with up to 40 % overload if the other is off. The final choice depends on the utility’s technical conditions.

    04How we work

    Scope, timing and result are clear up front

    Accountability

    Every stage has an owner, a deadline and a way to check it.

    Sound engineering

    Decisions rest on calculations, codes and real operating conditions.

    Safety

    We choose materials and installation methods to meet safety requirements.

    Transparency

    Before work starts you see the stages, scope and expected result.

    05Frequently asked

    The short answers

    Can you handle all the paperwork?

    Yes. We manage applications, technical conditions, design, approvals and final handover.

    Do you work with new 6–10 kV consumers?

    Yes. We design, build, test and commission 6–10 kV and 0.4 kV systems.

    Can I order design only or construction only?

    Yes. Services come as one package or as separate stages, depending on the task.

    How do I get a preliminary offer?
