Technical benefits Our VPI (vacuum pressure impregnation) technology ensures consistently high insulation resistance in our preformed coils. Rotor windings in double-fed generators are always designed as medium-voltage coils for high voltage gradients in converter operation, and we only use stainless-steel slip rings for grounding systems to ensure that our VEM wind power generators will easily meet the specifications for operation in harsh coastal or offshore environments. Redundant grounding systems and specifically designed bearing insulation ensure safe converter operation. We have a...
