The contract was awarded by NCS International Inc. for the medium voltage power and fiber optic cables, and Eptcon for the high voltage cables. The Niagara Wind Farm includes 77 3 MW wind turbine generators, resulting in a combined capacity of 230 MW (enough to power 70,000 homes).
The turbines are grouped into ten collector circuits that bring power to substations via 34.5 kV underground cable. The fiber optic cable will be used to collect and transmit critical wind condition information from each turbine.
The group will supply 25 km of 138 kV underground cable with aluminum conductor and XLPE insulation and more than 400 miles of 35 kV MV power cables to interconnect the wind farm to Hydro One Networks.
Prysmian will also supply the HV outdoor terminations and Click Fit jointing systems along with direct burial fiber optic cable. The medium voltage and high voltage cables will be supplied from Prysmian Group factories in Prescott, Ontario (Canada) and Abbeville, SC with the fiber supplied from Claremont, N.C.
