ABOUT US • The plants are suitable for Transformer Capacitor Manufacturers Transformer Repairers Transformer Owners Oil filtration service providers etc. These plants work on low temperature high vacuum principle. • We also developed Trickle Impregnating Machines for varnishing of electrical machines windings such as armatures rotors field coils stators. These machines are suitable for varnishing of electrical windings in mass production. Auto electrical parts mixers fans electrical motors Instrument transformers etc. are few to name. • We also manufacture Vacuum Impregnation Plants for big electrical windings and Vacuum Drying Ovens for drying of transformers capacitors etc. On line transformer oil regeneration plants are under development.

INDEX TYPE TRICKLE IMPREGNA TING MACHINE Trickle Impregnating Machines are suitable for automatic impregnating of stators and rotors by trickle process. Stators and Rotors are heated to pre-determined temperature and then trickled with varnish Resin + Hardener and cured until it hardens. They are then ready for unloading manually. They are rotated by chain drive which rotates the spindles mounted on rotating / indexing table at an appropriate speed suitable for trickling. Indexing Table is rotated by motor with gear box and limit or proximity switches. : 1. Job indexing system : Index table is mounted on a spindle placed in fabricated box containing main spindle bearings. It is indexed with the help of brake motor gearbox chain and main spindle. The index position is ensured by spring loaded index pin operated by pneumatic cylinder proxy switch reed switch PLC. 2. Job rotation system : Rotating spindles are mounted on the index table driven by electric motor gearbox chain and sprockets. An arrangement is provided such that when jobs come to loading - unloading station spindles stop rotating for easy removal and placement.

INDEX TYPE TRICKLE IMPREGNATING MACHINE • 3. Heating system :Stators and Rotors are pre heated and cured while passing through the pre heating zone and post heating zone. Radiation type electric heaters do heating in pre-heating and curing zone with temperature control by Digital Temperature Indicating Controller with proportionate temperature control. Both the zones are insulated with glass wool to minimize heat loss. Both the zones are lined with reflective aluminum sheet backed by asbestos cloth for efficient heat reflection and distribution. • 4. Varnish feeding system : Varnish is fed by peristaltic tube pumps driven by D.C. motors with variable speed control to control varnish quantity according to the models. Pneumatic tube positioning system is provided for proper varnish feeding. Total cycle is automatic except for loading and unloading. • 5. Centralized control panel : Index trickle impregnating machines is provided for complete preset automatic operation cycle except for loading and unloading. It is provided with cycle parameters settings such as pre- heating and curing temperature varnish quantity trickle time total cycle time etc. The PLC is provided to control the operation of the machine in proper sequence and safety.
