Since the approval by Network Rail of the 33kV oil transition joint over twenty years ago, Groove has been an established and approved supplier to the entire UK Utility power network for its range of medium and high voltage jointing accessories. Customers include Network Rail, Western Power, Balfour Beatty, Scottish and Southern, NI Electricity, Scottish Power, Electricity North West and Northern Power Grid. The 33kV oil transition joint has also been approved for use with NKT’s flat oil cable and the joint has been supplied to Eltel for use within the power utility networks of Scandinavia.

Underwater mateable electrical connectors are required to operate in the harshest of environments and ocean navigation buoys present the most arduous of these conditions. Groove initially established the supply of connectors in this harsh environment to Trinity Lighthouse over twenty years ago and have set the standard for underwater electrical connectors ever since. Customers now include manufacturers of ROVs, subsea ploughs and underwater vehicles, underwater cameras and subsea instrumentation including lights and diver equipment. These customers are well established across the UK and Europe.
