Medium and high voltage accessories for the Utilities industry and railway network

Groove has supplied medium and high voltage accessories for over 25 years. During this time, we’ve gained a reputation for competitiveness, reliability and innovation. Established customers include Network Rail, Balfour Beatty, Scottish and Southern, EDF Energy, Western Power Distribution, Scottish Power, Northern Ireland Electricity, Eltel, Electricity North West, Carrilion, Morgan Sindall and Northern Power Grid. Groove is an Achilles registered company.

Our 33kV oil to XLPE transition joint was approved by Network Rail more than 25 years ago and has since been approved by all UK Utilities companies. Approximately 500 units have been supplied with an exemplary reliability record. The joint is also being supplied to Northern Europe and is qualified for use with the NKT flat 33kV oil cable.

Following the success of the 33kV transition joint, Groove now has an approved 33kV gas to XLPE transition joint, 33kV oil to oil stop with XLPE tee off joint and 9 way XLPE breech joint. These are used throughout the UK Utilities network and on solar farms.

Groove recently introduced an armoured gas and oil supply line to support the joint products which is easier to terminate than competitive cable products, and is more cost-effective.

Groove is also an established supplier of low and medium voltage rapid response circuit protection equipment. We also supply mechanical shrinkage joints for XLPE and EPR cables rated at 138kV and 230kV.
