Power Transmission & Distribution

Supporting the society in the transformation towards a sustainable energy future by building new green transformer substations.

Power Transmission & Distribution

Championing the green transition in power transmission and distribution.

For 70 years, we have been providing a complementary set of products and services in the power transmission and distribution value chain. Our turnkey projects include building new, digital, and green transformer substations and reconstruction, expansion, and modernization of existing facilities with voltage levels ranging from 110 kV to 420 kV.

In the distribution segment, we specialize in building digital compact substations designed for a range of applications, operating at voltage levels from 6.3 kV to 40.5 kV, equipped with our proprietary products and solutions.

Power Transmission & Distribution
Design
Design
Focus on quality and smart environmental protection are integral to every project we undertake. Experience plays a key role, assuring success in equipment selection, development, and manufacturing, as well as in calculations and the design of transformer substations. In addition to devising solutions, our services extend to coordination of on-site operations and monitoring and maintenance of both completed and ongoing projects.
Construction
Construction
Our core expertise are construction of AIS or GIS transformer substations with voltage levels up to 420 kV. However, our competencies go further than that, and include installation of electrical equipment, cable laying, and grounding, along with all types of electrical works on advanced and industrial facilities.
Manufacturing
Manufacturing
Our major competitive edge comes from our core competence to independently manufacture and implement advanced solutions. We manufacture complete HV equipment for the construction of transformer substations. The journey starts from raw materials and culminates in an assembled, functional system - the result of our efforts, experiences, and competencies.
Maintenance
Maintenance
Continuous responsible maintenance and servicing of plants with the aim of extending the service-life of equipment delivers major value for our partners. Through careful monitoring and compliance with technical regulations and accepted standards, we achieve greater reliability and availability at lower costs.
Transmission substations
Field of Application

Transmission substations

We design, produce, and commission key infrastructure in the power grid, which includes equipment for monitoring, protection, and control of transformer substations. Our turnkey projects are executed as greenfield investments, revitalization, or expansions of existing stations.

Distribution substations
Field of Application

Distribution substations

Voltage regulation points that deliver power from transmission systems to residential and industrial consumers. We manufacture two versions of distribution substations - for outdoor and indoor installation. Our partners can rely on our comprehensive solutions that include equipment delivery, assembly, testing, and on-site commissioning.

Compact substations
Field of Application

Compact substations

Compact solutions are designed for e-mobility, data centres, renewable sources, and rural electrification. We deliver them on-site as comprehensive solutions, empowering customers to manage and maintain them easily in various municipal and industrial applications. The primary voltage levels of transformers in compact substation ranges from 6.3 to 40.5 kV.

Sub-Systems and Products

Proudly transmitting energy from the source to consumers worldwide

Transformer substations are a vital part of the power grid. We manufacture a wide range of solutions of this type and integrate equipment for their monitoring, protection, and management.

400/220/110 kV TS

Our flagship advanced product. The essential elements of each transmission substation are HV transformers, circuit breakers, disconnectors, instrument transformers, and GIS plants. Our portfolio also includes SCADA systems, transformer monitoring systems, busbars, and control, protection, and metering system.

100 kV / x kV TS for transmission and distribution area

Power distribution depends on these highly complex, advanced systems. The development of AIS and GIS stems from our expertise and know-how, with each unit being crafted with consistent precision and care.

Compact e-mobility stations

We have embraced the challenge of carbon-neutral mobility. We design compact transformer substations for MV electric charging stations up to 40.5 kV with a rated power of up to 3,500 kVA.

Compact substations for renewable energy sources

Our main priority is promotion of renewable energy sources. We offer three distinct types of compact substations for small wind farms and solar power plants: standard solutions, rectifier compact substations, and compact substations designed for solar power plants.

Compact substations for data centres

We develop compact transformer substations customized for data centres, designed to operate at MV levels of up to 40.5 kV and with a rated power up to 3,500 kVA. The crucial components of these substations include distribution transformers, AIS or GIS MV blocks, and LV distribution systems.

Compact substations for rural electrification

Compact substations for rural electrification are an ideal solution for remote communities where access to the grid is not easily available. Such facilities feature a HV instrument transformer and an AIS or GIS LV block.  The comprehensive solution is equipped with corresponding protection, management, and metering systems.

Construction of the new Žerjavinec TS and complete reconstruction of Ernestinovo TS - Croatia
Flagship Project

Construction of the new Žerjavinec TS and complete reconstruction of Ernestinovo TS - Croatia

The construction of the new Žerjavinec TS and complete reconstruction of the war-damaged 400 kV Ernestinovo TS remain key national initiatives carried out since the establishment of the Republic of Croatia. The reconstruction of Ernestinovo TS created pre-conditions for the interconnection of the transmission grids across CSEE Europe.

We are proud to have served as the leading power engineering company in these projects, effectively executing the design, procurement, and the delivery of electrical equipment on schedule. The scope of work also encompassed the organization of assembly works and specialist testing during commissioning.
