EDF Energy Contracting completed a project to install a new 11kV ring main at University College London. Three HV substations at University College London that used to be part of London Electricity's network were to come under private ownership and be connected together in a ring main.
Many of the building facades at UCL are grade 1 listed and as such could not be altered to allow for cable entries. Hundreds of metres of 300mm2 3-core HV cable were laid in cable ducts that had to be buried under the roadway at the university campus.
EDF Energy Contracting carry out construction projects at 33,000 and 132,000 volts on ground mounted and overhead plant and equipment. Recent projects include erection of 132kV overhead busbars supporting insulators and isolators associated with the 132/33kV transformer changes and the erection of 132kV Hapam isolators and busbar work at several major sites for Siemens Ltd within the South East of England.
EDF Energy Contracting carry out the maintenance of all Southern Water Supply Works Pumping Stations and Water Treatment works in Kent, Sussex, Hampshire and the Isle of Wight.
These sites are maintained throughout the year dependIng on the customers' operational requirements ranging from yearly substation inspections, full site maintenance and pump maintenance to trip testing site supplies.
This school’s many wonderful buildings, including the Sports Centre and Theatre, are set in extensive grounds, making a private HV system comprising of 9 sub-stations and 4km of underground cable, the most economic and effective means of power distribution over the 250 acre site. In 2000 a planned redevelopment scheme for the old redundant boiler house, laundry and swimming pool building, coupled with ever expanding school facilities, highlighted the need to address several long standing issues regarding the existing HV distribution network. These were identified as the need to firstly improve the existing distribution network configuration, changing the old radial feeder system into a ring circuit, thus improving its reliability and operational flexibility.
