Trench Group acquires Australian technology firm H Nu
Berlin (Germany), 30 September 2025 - Trench Group, a Triton Fund V portfolio company and a world leader in power engineering and the design of specialised high voltage electrical products serving utility and industrial customers around the globe, has acquired the Australian technology firm H Nu, expanding its portfolio with cutting-edge fiber-optic instrument transformer technology. This acquisition enables Trench Group to deliver ultra-fast response times in power transmission operations. While the technology supports all transmission types, it offers particular advantages for High Voltage Direct Current (HVDC) systems.
Initial fiber-optic units have already been successfully deployed in transmission grids worldwide. Trench is collaborating with leading system suppliers to qualify this technology as a future standard for high-voltage measurement – laying the groundwork for rapid scale-up and series production.
The integration of H Nu reinforces Trench Group’s position as a global leader in innovation and technology for high-voltage transmission components. H Nu’s expertise in fiber-optic measurement complements Trench’s existing capabilities.
“This marks Trench Group’s first acquisition. H Nu’s technology will benefit from our leadership in HVAC and HVDC systems and our global market reach,” says Dr. Bahadir Basdere, CEO of Trench Group. “We’re excited to offer our customers the latest advancements in flexible, fast-reacting systems and power quality solutions – this is critical as global power grids grow increasingly complex.”
This acquisition underscores Trench Group’s role as a reliable, forward-looking partner for system-critical power transmission solutions.
