Why “White Coils” are a “Red Flag”

The importance of preventing the ingress of air during global vacuum pressure impregnation of form-coil windings

  • September 2022
  • Number of views: 978
  • Article rating: 5.0
Article

The goal of vacuum pressure impregnation is complete saturation of a winding with insulating resin. As resin penetrates the insulating materials, it causes them to darken. If some insulation is a lighter shade, the coil or jumper is not fully saturated. The winding is not properly protected, and if the problem is not addressed, it is likely to cause premature failure of the unit. This could result in costly warranty work, or at a minimum, will be a failure to provide your customers with the quality they expect and deserve.
