Why work with us

We select transformer equipment to the site parameters, operating conditions and power supply requirements. We provide full support — from technical selection to equipment delivery.

  1. Wide power range

    We supply equipment from compact transformers to high-power systems for high-voltage substations.

  2. Dry-type and oil-immersed versions

    We select the optimal transformer type for the installation site, fire safety requirements and operating conditions.

  3. Standard and custom solutions

    We work with standard equipment as well as technical solutions for non-standard HV and LV parameters and transformation ratios.

  4. Complete packages

    We select the required accessories, regulation systems and additional equipment to the project parameters.

Why choose us?

Precise equipment selection

Precise equipment selection

We analyse the technical brief and select the transformer by power, voltage, design type and operating conditions.

We analyse the technical brief and select the transformer by power, voltage, design type and operating conditions.

We supply equipment for local transformer substations, industrial sites and high-voltage power systems.

We offer equipment that meets DSTU requirements and modern energy efficiency standards.

We arrange configuration, logistics and delivery of the equipment straight to the customer’s site.

Need a transformer for your site?

Send us the technical brief or the main equipment parameters. We will select the optimal solution and prepare a proposal covering configuration, cost and delivery time.

Direct supply from manufacturers, controlled lead times and reliability at every stage.
