Description

Offered From : Europe

  • Reduced initial capital expenditure and lower operating costs.
  • Light weight with high power to weight ratio.
  • Reinforced insulation superior to Class F with Class H VPI, temperature rise limited to Class F ensuring high insulation strength & protection from environment.
  • Non sparking material for fans. Caulking of rotor bars for tight fit in rotor slots.
  • Pre-start purging facility for removal of hazardous gases from the enclosure before starting (Purging instrumentation is optional).
  • Minimised vibrations, noise and longer bearing life through minimised unbalance at every stage and precision balancing of Rotors using state of art dynamic balancing machine to grade better than 1.0.
  • Maintaining adequate clearance between stationery and rotating parts.
  • Providing adequate clearances and creep age paths between live phases and between phase and earth in the terminal boxes.
  • Providing positive locking features for terminating the cables to guard against loosening of the termination due to vibrations etc
