Electrical Performance
Insulation System

Class H insulation with special materials and advanced lacquer immersion technology. Varnish and colophony materials strengthen winding and rotating part mechanical integrity for corrosive environment operation.

Winding Characteristics

2/3 pitch winding effectively eliminates voltage harmonic waves (3rd, 9th, 15th), making it ideal for UPS applications with nonlinear loads. Continuous damp windings reduce voltage surges.

Interference Control

THF (BS4999) <2%, TIF (ASAC50.12) <50. Brushless design and quality AVR minimize radio interference, with optional RFI noise filter available.

Quality Assurance
  • Each unit undergoes 4+ hours of commissioning testing
  • Comprehensive testing includes idle load, full load, and 10% overload conditions
  • Noise level verification and control panel meter calibration
  • Complete visual inspection of appearance, labels, and nameplates
