ABB has supplied and advised in the implementation of power protection and isolation using special medium voltage switch-fuse combination switchgear in unit substations for one of the country’s largest wind power projects – the Longyuan Mulilo De Aar 1 and 2 wind project in the Northern Cape, with an expected installed capacity of 100 and 139 MW respectively.
ABB’s NALFWind 36 kV switch-fuse combination units will be incorporated into 163 unit substations as part of a R15 million order from Adenco Construction, the EPC (engineering, procurement and construction) contractor for the R5 billion wind project, which was part of the third round of the DoE REIPPPP programme.
The R15 million order from Adenco includes the supply and delivery of 163 ABB 36 kV NALFWind switchfuses, 20 ABB 36 kV OVB-VBF outdoor vacuum circuit breakers and 10 ABB 145 kV LTB SF6 circuit breakers. The MV and HV equipment will be supplied by ABB’s local Electrification Products and Power Grids divisions. The first delivery of the breakers and fuses from ABB will begin in May 2016 and complete delivery is expected in October 2016.
