33kV Jointing for Renewables and Critical Infrastructure
33kV systems typically come with tighter controls, higher consequence and more coordination across civils, cable routes, substations and commissioning. We integrate with your programme and focus on safe, clean workmanship delivered without drama.
- 33kV straight joints — XLPE insulated cables, cold shrink and push-on systems
- 33kV fault repairs — joint failure and cable section replacement
- Indoor and outdoor 33kV terminations
- New 33kV circuits and connections for solar farms, wind, BESS and grid infrastructure
- Multi-phase build and phased energisation support
- Testing and commissioning coordination
Sectors We Support at 33kV
Our 33kV jointing experience covers a range of sectors and network types:
