The manufacture of 3 core fluid filled cables has cease in August 2008 when Prysmian closed the factory at Eastleigh, Hampshire. There are currently two manufacturers providing a joint for this purpose but both joints are very large and require a joint hole about 12 metres long and 3 metres wide. The practicality of installing these joints in built up areas will be very difficult and may entail laying long lengths of cable to find suitable joints bays.
It is proposed to develop a new 132kV 3 core fluid filled cable to single core polymeric cable trifurcating joint.

The aim of this project is to develop a new joint that can be installed in a much shorter joint bay and use a plug and socket connection for the polymeric cable. Most of the components used in the joint have already been designed and type tested but have not been used in this combination before. The project is to design a suitable joint with the design, testing and manufacture of the joint carried out by G&W in USA.
