Trench Group Strengthens Composite Insulator Capabilities with RPC Acquisition

Trench Group and Maschinenfabrik Reinhausen announce the signing of an agreement for Trench Group to acquire the composite insulator production assets of Reinhausen Power Composites (RPC). The acquisition includes all key machinery, equipment, software, and intellectual property necessary for the engineering, design, and manufacturing of RPC’s full hollow-core composite insulator portfolio.

Composite insulators are vital components in the transmission and distribution (T&D) industry. They are integral to the performance and reliability of high-voltage equipment across global power grids, making them essential to ensuring secure and uninterrupted electricity supply.

The transfer of assets is scheduled to begin in the summer of 2026. The equipment will be relocated to Trench Germany GmbH in Bamberg, expanding the existing production setup that already manufactures composite insulators up to 800 kV.

This agreement marks a significant milestone for our industry. We are combining two areas of excellence to better meet the rapidly growing global demand for composite insulators. In recent years, our industry has faced capacity constraints. By acquiring RPC’s IP, engineering and production assets, we are strengthening our vertical integration while continuing to pursue a balanced ‘make and buy’ strategy. We will continue to expand and support our trusted partnerships with existing suppliers. Our customers will benefit from shorter lead times and enhanced supply reliability.
