ABB has been awarded a contract by Lilleker Brothers Ltd, the Rotherham based electrical installation and power engineering company, to supply a complete package of MV (Medium Voltage) switchgear and transformers for a distribution substation project in the oil-rich Niger Delta region of southern Nigeria.
The MV package, comprising ABB’s ZX1.2 (33kV) and ZX0 (11kV) ranges of primary gas insulated switchgear together with a pair of 7.5MVA, 33/11kV, liquid filled transformers, will be installed at a newly constructed substation in Opobo as part of a project by the Niger Delta Development Commission (NDDC) to reinforce the public distribution supply between the towns of Ikot Abasi and Opobo.
The Opobo substation is located on the island of Opobo and the 11km 33kV supply from Ikot Abasi will be supported on 132kV double circuit lattice transmission towers to allow for future upgrade of the supply to 132kV. The route of the towers has to negotiate mangrove swamps, and also includes a pair of 85 m high towers to span a 900m crossing of the Opobo river.
