Implementing 420kV Dry-Type Shunt Reactors into Transmission Grids represents one of the most outstanding achievements in Air Core Dry-Type Reactor technology ever. This milestone results from more than one decade of hard and dedicated work in Trench`s R&D, Engineering, Sales, Business Development, and all other functions. Without our customers already using High Voltage Dry-Type Shunts and giving us the chance to learn from their needs, all that would not have been possible.
