Wimbledon Cable Relocations
Project Overview
Cleshar had responsibility to relocate respective HV cables into newly installed troughing routes. Particular attention was paid to staging and the methodology of the works due to the complexity associated with Wimbledon Station and the services, particularly HV, running through Wimbledon and the risk associated with failure.
Scope of Works
- Designing, planning and installation of the HV, Fibre Electrical Track Equipment (ETE) and Signalling Cables along with ancillary civils works.
- Implementing alterations to signaller panels to remove the ability to select routes to and from Platform 10.
- Removing all outdoor signalling equipment, including track circuits
- Relocating 33kV High Voltage (HV) Feeder Cables through a track slab
- Slewing S&T cables into permanent routes
- Relocating and making alterations to ETE cables
- Undertaking surveys to develop the signalling, ETE and HV designs
- Conducting design reviews and checks with Network Rail
Innovations
We undertook the relocation of the HV works over 2 blockades and 2 weekend closures. The relocation works saw us recover redundant cables, install 4 new HV feeders and pilot cables.
We relocated, jointed and section-proved all ETE cables over the weekend closures. We carried out hot site testing before any works to establish safe places of work. This involved the manning of several substations with Level A Engineers during the works.
We undertook temporary wiring solutions which reduced risk against programme. We planned, staged, and delivered the works alongside Network Rail’s ECRO and HV Teams and managed the works through several stage gate reviews.
Benefits / Project Outcome
We successfully delivered all blockades and possession and handed back on time with no impact to services.
We installed and changedover new HV & pilot cables without any disruption to the existing
