Network Rail

Groove has been supplying Network Rail with our CTM -11, 33kV Oil Transition Joint since 1992 when it was qualified in Chicago with the “Hotsplicer” Corporation and British Rail.

We have supplied nearly 300 joints to the UK railways network since this date with an exemplary service history and robust reliability with the ability to adapt when required. It still remains Network Rail`s favoured joint when re-routing oil cable and upgrading TP Huts and Sub Stations.
