TRENCH AUSTRIA MILESTONES
the years that marked our history
Start of the Dry Type Air Core Reactor Production
Company foundation “Spezielektra” by Alois Esslinger – Production and sales of air core reactors made of disk type windings, impregnated by varnish
Arc Suppression Coils up to 30 kV
Development and extension of the portfolio with arc suppression coils (oil immersed reactor with mechanically adjustable iron core) up to 30 kV rated voltage. Expansion of the portfolio to 145kV since 2000
Air Core Reactors with Layer Type Windings
New development of air core reactors with concentrically arranged and electrically parallel connected layer type windings and trickle impregnation by epoxy resin. This technology has been also used for shunt reactors up to 45kV since 1982.
Earth Fault Compensation Controller EA76
Development and delivery of the first full electronic earth fault compensation controller type EA76 (for the control of adjustable arc suppression coils).
Dry Type Smoothing Reactors for HVDC Converter Stations
Delivery of a smoothing reactor for a 350 kV HVDC transmission connection. Because of the technical and commercial advantages, air core smoothing reactors superseded the previously used oil-insulated iron cored types.
Voltage Sourced Multilevel HVDC Schemes (MMC) Using Power Transistors
Design and delivery of the HVDC converter reactors for an off-shore MMC project. Trench becomes part of the energy transition towards renewables. Also, these reactors are equipped with the electrostatic shield, developed and patented in 2008.
Dry Type Smoothing Reactors for 800kV UHVDC Schemes
Design and delivery of 800kV UHVDC smoothing reactors for the world’s first UHVDC multiterminal project.
Earth Fault Compensation Controller EFC60 and EFC60m
Release of the actual version of the controller including optional multi-frequency current injection features. The device features a modular approach and a full color touch display.
Advanced Residual Current Compensation (ARCC®)
Delivery of the first units to Australia. This technology is designed to mitigate the risk of bushfire caused by power line failures.
500 kV Dry-Type Air Core Shunt Reactors
After the worldwide first delivery of 420 kV dry type air core shunt reactors in 2021, the prototype of a 500 kV air core reactor has been successfully tested.

FOCUS ON
TRENCH AUSTRIA
INNOVATIVE TEST LAB
We are setting the trenchmark. Each of our dry-type reactors must pass our innovative test lab in order to meet our high-quality standards.
Our commitment to sustainability
As proud market leaders, we are responsible for building a sustainable outlook for future generations. Therefore, sustainability is not just a word, but our mission and an integral part of our strategy and daily actions.
Education
"Rotkreuz-Lerninsel" education project
Supporting 22 children with educationally alienated background through the education initiative of the Red Cross.
Energy efficiency
Let there be L(ED)ight!
Change over to energy efficient LED lights incl. a partial implementation of motion and presence sensors.
