Slide 6: Product Profile
Slide 7: DRY TYPE TRANSFORMER
Slide 8: The major components of Dry Type transformers are:
Core
Winding
Epoxy Resin
Fiber Glass Mat
Fiber Glass End Blocks and Cylinders
Enclosure
Marshalling Box
Epoxy Bushings and Insulators
Temperature Scanner and PT-100.
Slide 9: 1): Windings-
Copper conductor is used for the winding of both LV &
HV. After the winding wound coils are placed in separate
steel mould.
2): Casting-
Casting is done by utilizing the unique properties
offered by pure liquid epoxy system.
3): Cutting and Dressing
4): Assembly of Transformer MANUFACTURING PROCESS OF DTT:
Slide 10: CHARACTERITICS & FEATURES OF DTT: Self-extinguishing and fire retardent
Maintenance free nature
Immediate switch on
Resistance against temperature fluctuation
Space saving
Lower losses and higher effienciency
Moisture proof
Increased in performance by forced cooling
Nonpolluting
Slide 11: APPLICATION OF DTT: Power Plats-thermal, hydro, nuclear plants
Steel rolling
Oil rings and refineries
Chemical and Fertilizer plants
Metro railways
Underground Sub station and Milling
Slide 12: POWER TRANSFORMERS
Slide 13: The major components of power transformers are:
Core
Winding
Tank & Fabricated fittings & Accessories
Marshalling Box & RTCC panel
Transformer Oil
Radiators, fans, pumps or OFWF coolers
OLTC ( On load tap changer)
Bushings
Buchholz relay
Slide 14: TRACTION TRANSFORMERS
Slide 15: All assemblies, requirement of material & components and process for manufacture for traction transformers is similar to power transformers.
Traction transformer require special HV cable bushing termination to connect to overhead catenary.
All the material & stages of manufacture of traction transformer are inspected by RDSO & require their approval.
Slide 16: ESP
