Končar d.d. products

Our turnkey hydro generators are designed and manufactured to meet customer-specific needs. We have a long history of successfully revitalizing hydro generators from various manufacturers, customizing our approach to fit the particular needs of each project.

An all-in-one excitation system for brushless and small synchronous generators, motors, and motor-generator sets. With its compact design, small dimensions, and integrated power converter, the KONreg S1000 is the perfect fit for brushless synchronous generators, motors, and motor-generator sets. It supports a variety of communication protocols and comes equipped with multiple communication interfaces, providing flexibility in integration.

Compact, high-power solutions for synchronous generators and motors of all sizes. Our static excitation systems, featuring KONEX, KONREG, and DRN digital voltage regulators, are built on advanced, programmable processing units that enable precise real-time control and regulation. With their fast response times, exceptional accuracy, and robust reliability, they deliver top-tier performance across various applications.

DC uninterruptible power systems are indispensable in modern power facilities, providing the highest level of operational reliability. Unlike AC UPS systems that rely on inverters to convert battery voltage, DC systems offer direct, seamless support to critical loads, making them a superior solution for ensuring power continuity.

We distribute AC uninterruptible power supply systems from the world-renowned brand RielloUPS. Designed to provide uninterrupted, reliable power for critical applications, these systems offer cutting-edge solutions to ensure continuous operation and protect against power disruptions.

We design and manufacture high-voltage circuit breakers of type 8E1, optimized for rated voltages of 123 kV and 145 kV with nominal currents of up to 4000 A. These breakers are available in both single-pole and three-pole configurations, utilizing dependable motor-spring operating mechanisms for precise and efficient operation.

We design and manufacture high-voltage disconnectors and earthing switches of type CB-N2, engineered for rated voltages up to 420 kV and nominal currents of up to 4000 A. 

Single-phase transformers are generally designed with a core on two legs or a single leg with two return legs or auxiliary core legs. The most common application for single-phase transformers is in railway systems. However, we also manufacture power system transformers that are configured as three single-phase units, which are ultimately connected into a three-phase system on-site. These transformers can be filled with mineral oil, natural, or synthetic ester liquids.

Three-phase transformers represent the largest segment of the transformer industry and are designed to meet specific customer specifications and requirements. Despite the numerous design variants, notable examples include two-winding transformers, three-winding transformers, transformers with voltage switching on the low-voltage or high-voltage side, transformers with stabilization windings, generator transformers, and more. These transformers can be filled with mineral oil, natural, or synthetic ester liquids.
