KONČAR – Switchgear

We have developed most of the power infrastructure in Croatia and the region. What’s the key to our success? Our formula for success hinges on embracing innovation, aligning with current trends, and integration of cutting-edge technologies.

KONČAR – Switchgear

Adaptability in power transmission & distribution

We are an acclaimed manufacturer of power transmission and distribution equipment -  LV switchgear, MV switchgear for primary and secondary distribution, and HV switchgear for transmission.

Back in our early days, more than half a century ago, our operations were based on licenses from other manufacturers. Today, we independently develop almost all of the products in our portfolio. Alignment with market trends is fundamental to our growth and development.

GIS plants
Switchgear

GIS plants

Our three-phase GIS metal enclosed switchgear K8D.6-N type is optimized to meet the challenges of power grids of rated voltage up to 123/145 kV.

Some of the many benefits of these solutions include easy and fast installation and on-site commissioning, resistance to environmental impacts and enhanced operational safety and reliability.

HV circuit breakers series 8E1
Switchgear

HV circuit breakers series 8E1

Three-pole or single-pole operated solutions for rated voltages from 123 kV up to 145 kV, rated current 3,150 A and 40 kA short circuit rating with reliable motor-spring operating mechanism.

In addition to the standard electrical auxiliary equipment, we equip the circuit breakages with a test connector for auxiliary circuits that can be used for monitoring or diagnostics over the course of service-life.

HV disconnectors series N2
Switchgear

HV disconnectors series N2

We manufacture single-pole or three-pole disconnectors and earthing switches with a central opening for outdoor installation, rated voltages up to 420 kV and rated current up to 4,000 A, with rated breaking capacity of 50 kA, 3 s. We prioritize safety and reliability, with every disconnector type engineered to resist seismic forces, adhering to a ground acceleration threshold of 0.5 g.

BVK series switchgear
Switchgear

BVK series switchgear

BVK switchgear is widely applied in power distribution, generator plants, test laboratories, and industrial facilities.

BVK type switchgear panels are constructed to accommodate a broad spectrum of nominal parameters, including rated voltage ranging from 12 to 38 kV, rated current ranging from 630 up to 3,600 A, and a nominal short-time withstand current up to 40 kA.

KSMA series compact switchgear
Switchgear

KSMA series compact switchgear

We manufacture metal enclosed switchgear plants for primary distribution using our compact KSMA series modules, designed with minimal overall dimensions.

In addition to the mandatory manual control, the modules offer remote control capabilities for all devices. This feature enables complete automation of the plants, making them a fundamental component in the construction of smart grids.

KSMV series compact switchgear
Switchgear

KSMV series compact switchgear

We manufacture single-pole or three-pole metal enclosed switchgear for primary distribution, rated voltage up to 420 kV, rated current up to 4,000 A, with rated breaking capacity of 50 kA, 3 s. 

Designed with minimal overall dimensions, the solution ensures a higher degree of power supply continuity. Compact modules series KSMA are designed for indoor installation at normal service conditions.

VDAΣ series vacuum distribution switchgear (ring main unit)
Switchgear

VDAΣ series vacuum distribution switchgear (ring main unit)

MV compact switchgear (ring main units) series VDAΣ are designed for nominal insulation level 24 kV. Their main purpose is secondary distribution of electrical energy in transformer substation up to 2,500 kVA; 10(20)/0,4 kV.

Vacuum distributive compact ring main units series VDAΣ is characterized by high reliability and availability. The overall dimensions have been minimized in comparison to classic AIS equipped with load break switches.

VKΣ and VK series MV vacuum circuit breakers
Switchgear

VKΣ and VK series MV vacuum circuit breakers

New generation of vacuum circuit breakers series VK circuit breaker developed and designed in compliance with up the latest national and international standards.

Developed in compliance with the requirements of IEC 62271-100, the circuit breakers are available for a wide range of rated parameters.

Ru series MV voltage disconnectors for indoor installation series
Switchgear

Ru series MV voltage disconnectors for indoor installation series

We manufacture disconnectors for indoor installation with voltages ranging from 12 to 38 kV, rated currents from 630 to 2,500 A, and short-circuit currents up to 50 kA, 1 s.

The disconnectors can be equipped with one or two earthing blades. We offer several types of disconnector drives - manual (toggle-joint) operating mechanism, types S-5 and S-15, electric motor drive, type EMP-25 and pneumatic drives type Zp 8/9 and Zp 10/13.
