1) Technical Features
Insulation and Protection
The standard insulation system of low voltage generator is class H. The standard insulation system of Medium/high voltage medium speed generator is F class while H class is optional. Adopting high grade insulation paint and advanced impregnating tehnology with multiple layer insulation protection to the stator & rotor assembly, it fully ensure the generator can withstand harsh environment conditions.
Patent Stator Winding Structure (SWS) of Low Voltage Generator:
Enhance the inter-phase insulation strength at the end of winding to protect any short circuit problem among each phase. Enhance the mechanical strength at the end of winding to effectively prevent and withstand the deformation at the end of stator caused by sudden load or short circuit.
Patent Rotor Insulation Structure (RIS) of Low Voltage Generator:
Patent triple insulated structure of rotor coil can effectively improve the rotor turn to turn and interlayer insulation, accordingly the damp-proof and anti-corrosion ability, the life span, reliability and environment adaptability of generators is also substantially improved.
Stator of High Voltage Generator :
Class F stator coil is wrapped with class F epoxy mica tape and mould pressed. Class H stator coil is operated with the mature class H insulation technology and imprenated in VPI (vacuum pressure impregnating) system. Both class F and class H stator coil are processed with anti-corona treatment. Meantime, the stator coil is designed with skewed slot structure to effectively reduce harmonic wave.
