R&D Cable Jointing provides HV cable terminations for 11kV and 33kV systems across the UK. We install indoor and outdoor terminations into switchgear, transformers, RMUs and substations, supporting both planned installation works and repairs. Based in Kent and working nationwide, we regularly support projects across Essex, London, Kent, Hertfordshire, Surrey, Suffolk, Cambridgeshire and Bedfordshire.
Termination Types and Applications
All terminations are installed in accordance with manufacturer instructions and site requirements. We focus on clean preparation, controlled build-up and proper stress control to ensure long-term reliability.
- 11kV indoor terminations — into RMUs, switchgear panels and transformer LV connections
- 11kV outdoor terminations — pole-mounted and outdoor substation applications
- 33kV indoor terminations — into switchgear, transformers and busbar chambers
- 33kV outdoor terminations — grid and substation interface points
- Cold shrink termination kits — clean and reliable in all environments
- Heat shrink termination kits — for XLPE and PILC cable types
- Slip-on (push-on) termination systems — rapid installation on XLPE cables
Terminations into Specific Equipment
- Ring Main Units (RMUs) — 11kV cable terminations into LVCB and fuse switch positions
- Pole-mounted transformers — outdoor LV and HV side terminations
- Ground-mounted transformers — oil-filled and dry-type units
- 11kV and 33kV switchgear panels — cable box terminations and bushing connections
- PILC to XLPE transition termination points
Preparation Standards
Proper termination preparation is critical to long-term performance. Our approach is methodical and unhurried — we do not cut corners on preparation, stress cone positioning or screen termination management, regardless of programme pressure.
- Cable stripping to manufacturer tolerances
- Screen management and earthing connections
- Stress control geometry — correct positioning to manufacturer specification
- Environmental protection for outdoor installations
- Post-installation inspection ready for test team
