Description
London Underground operates and maintains a High Voltage (HV) Power Distribution Network, which includes multiple bulk supply in take points that distribute HV power to substations and distribution points through HV cables. These cables, which are 11kV and 22kV, are installed across the London Underground rail, public highways, and Network Rail Infrastructure.
The existing network consists of cables over 80 years old, ranging from single and three-core Paper insulated Lead cables to Polymeric cables, with sizes varying from 70mm² to 630mm².
In addition to managing HV cables, the HV Cables department also manages the control cables within the power estate, including both copper Pilot and Fibre Optic cables.
To effectively manage fault repairs and maintain both HV and Pilot networks, the HV Cables department requires the ongoing support of a specialist contractor. This contractor will play a key role in assisting with power upgrades through project works.
This aims to secure a commercial partnership with a specialised contractor who possesses the expertise and experience necessary to support both planned and reactive maintenance for the London Underground HV infrastructure.
The services will cover maintenance, repair, fault finding, project support services and purchasing of cables to be installed.
