Reactors and Combi-Transformers – Power Network Stability and Efficiency

Reactors and combi-transformers supporting voltage control and reactive power management.

RE-Tech delivers tailored reactors and combi-transformers for demanding transmission and distribution applications. Our solutions are ideal in use cases requiring voltage control, reactive power compensation, or earth fault current limitation—such as renewable energy projects and utility substations.

What is a Reactor?

A reactor is an electromagnetic component used in power networks to limit earth fault currents or compensate reactive power. Typical applications include:

  • Reactive power compensation for cables
  • Earth fault current management in distribution networks

Combi-Transformers – Multi-functional Solutions

  • A combi-transformer integrates a distribution transformer and a reactor into one unit, offering a compact, efficient, and cost-effective solution. Especially beneficial in space-constrained installations or when minimizing separate components is desired.

    Benefits:

    • Saves space and installation costs
    • Improved system integration
    • Single delivery, reduced cabling

Typical Applications:

  • Urban distribution networks – fault and reactive power control
  • High-voltage cables – reactive power compensation

Sustainable and Responsible Solutions

RE-Tech invests in environmentally responsible technologies—our reactors and combi-transformers are designed for long-term operation and demanding conditions. Where possible, we use eco-friendly materials, biodegradable insulating oils, and recyclable designs.
