8 March 2004 � Alstom has set a benchmark by completing a generator rotor rewind in 22 days, against the industry standard of 42 days. This project was completed for the 660 MW Majuba power plant, owned by Eskom, located in Volksrust, South Africa.
Due to fuel supply restrictions the generator units are currently operated for system peak lopping. As the plant did not have a spare rotor available, the rewind work had to be done within an outage period.
The challenge for was therefore to plan a 22-day rewind within the 42-day outage programme, identify and deliver to site all of the necessary materials, consumables and tooling required to complete the work.
The rewind work was completed in Rosherville workshops, in Johannesburg, which is owned by Rotek Engineering, a subsidiary of Eskom. A team of Alstom winding experts supported Rotek workshop staff throughout the project.
