Turbine generator rotor turn insulation

Turbine generator rotor designs place stringent requirements on insulation. The insulation, operating at Class B temperatures, must withstand mechanical and electrical stresses for the life of the machine as well as maintaining accuracy of insulation alignment. A turbine generator is expected to operate for at least 20 years on a continuous basis without in-service insulation failures. These objecitves are attained using specially selected materials and designs and improved processing.
