We build on our own production. We supply transformer substations and switchboard as complete solutions - from design through production to assembly and service.

Our production program also includes sheet metal processing, metalworking, and the production of aluminum windows, doors, and ventilators.

Every detail matters

Designed for durability

When producing transformer substations, we use a special proprietary mix of high-quality concrete that meets all applicable norms, technical standards, and certification requirements.
We emphasize strength, weather resistance and long-term durability of the structure.

Control over every element

We manufacture our own aluminum and fire doors for transformer substations, designed with an emphasis on safety, functionality and long-term durability. Each solution can be customized technically and dimensionally according to the requirements of a specific project.
Our solutions also include various types of roof structures - from flat to pitched roofs and trusses - designed with the functionality, statics and aesthetics of the building in mind.

Reliability inside

We manufacture Low-voltage switchboard according to the project documentation and technical requirements of a specific solution. We design each switchboard with an emphasis on safety, reliability and long-term operation, using high-quality, proven components and implementing solutions up to 6300 A.
Our solutions also include our own system of grommets , which we developed for safe sealing and reliable routing of High-voltage and Low-voltage cables in various installation conditions.

Every detail matters

Tailor-made solution

We design the structural solution of transformer substations individually - either as a standard type solution or exactly according to the customer's project documentation.
Wall thicknesses and structural details are always adapted to the purpose of the building, static requirements and the environment in which the substation is installed.
