Trickle Impregnation Technique

 
Trickle impregnation technique was evolved to improve the varnishing quality coupled with reduced cost. This technique is now well accepted and used for impregnating stators / fields and armatures / rotors in all the advanced countries.
 
According to the principle of Trickle Impregnation, activated resin is trickled in a thin jet on to the rotating preheated winding. The resin immediately gets heated and its viscosity is reduced. Due to the rotary motion of the winding the resin gets distributed evenly inside the winding without any drain loss. The heated winding accelerates the gelling and curing of the resin.
 
The resin applied on the winding is quickly sucked through the slots. Assisted by the capillary action it pushes out the trapped air from the small voids and gaps in the winding and penetrates evenly in all the voids.
 
The essential point for successful application of the trickle impregnating resin is the fine

setting and the control of the winding temperature.
 
  DESIGN OF TRICKLE IMPREGNATION PLANT
 
The design of a Trickle Impregnation Plant plays a vital role in ensuring the uniform quality of a trickle impregnation. Any trickle impregnation plant should have the following essential features.
 
  • Machines are with Automatic Impregnation Cycle, independent of operator.
  • Arrangement for quick mounting and for making the connections of resistance heating.
  • Precise temperature control of the winding.
  • Accurately metered resin quantity required for the component.
 
The trickle impregnation plants with the above features are custom built taking into account several factors such as production rate, size and shape of the component, type of trickle resin etc.
 
  Advantages of Trickle Varnishing:
 
  1. Small space requirement
  2. Continuous Cycle
  3. Short Impregnation cycle
  4. No drain loss
  5. Good void filling
  6. No post cleaning
  7. Improved Mechanical strength
  8. Small impregnation tank
  9. Accurate resin quantity
  10. Lower environment pollution.
