Booster LV Electrical Distribution: Schedule and Quantities

Aims:Modernisation of Booster electrical infrastuctureTo install necessary infrastructure for transparent change-over of cablingMinimise impact on other work planned for the Booster (esp. cable removal campaign)Remove power cabling from false floor for easier installation + operation

Phasing:Phase 1 – New containment installation + Switchboards - YETS 2015 Phase 2 – Cable & Busbar installation - >YETS 2015 (During run)Phase 3 – Change over - EYETS 2016? TBA with usersPhase 4 – Cable removal – following change over, EYETS?

Quantities for removal:33 Cables to be removed (identified so far, however final number will be >> as no cablotheque exists for the majority)>1.6KM total cable length to be removed (identified so far)

Quantities for installation:BRF2 new rack zone – Additional ~100m containment to install, notional duration 2 weeksRefurbishment BCER zone – Additional ~400m containment to install, notional duration 3 weeksAdditional holes to be drilled for replacement of electrical supplies to distribution switchboards
