6 Power & Distribution Transformer For efficient power supply, well engineered and reliable transformers are essential. SERVOSTAR with its Two decades expertise in transformer has established state-ofthe-art facilities for distribution and power facility. Power Transformer We manufacture power transformers upto 2 MVA capacity with 11/22/33/66 KV class. Transformers cores are built with CRGO, low loss silicon steel lamination. Use of High grade and laser scribed laminations for the core significantly reduces no load losses and noise levels as committed. Power Transformer winding are made of electrolytic grade copper with continuously transposed conductors as per the designs requirement. The winding has axial and radial cooling ducts to ensure effective heat dissipation into the oil and elimination the hot spots. For high voltage windings, disc coils with excellent mechanical strength are used to take the stresses due to voltage level. A special interleaved or shielded construction offers most uniform voltage distribution despite system transients. Power Transformers, core-oil assembly are rigidly supported by a common pressure ring of dandified wood at the top and bottom, for precise alignment. Well profiled angled rings are placed between HV and LV windings to reduce voltage stress levels. The ends an tapping leads to all the windings are connected by special extra flexible, insulated coppers cables, which are rigidly braced in position. The core-coil assembly is put into the tank with proper locating arrangements. The tank is then filled wi th hot oil, filtrated by high vacuum Oi l filtration plant. Power Transformers. Tanks are built with mild steel plates to withstand full vacuum. conforming to the international Standards. Lugs for Jacking, lifting and hauling are routinely tested for dye penetration. Tanks have welded or bolted top cover. Tanks are shot blasted to get a surface finish to have double coat of Epoxy paint after double coat of Epoxy primer. The transformer is made ready for final inspection after assembly of bushings. conservator, radiators etc.

7 Isolation Transformer Isolation Transformers are effective and sensitive equipment which save from Line Voltage transients, Spikes & DC Leakage etc. They are specially designed for sensitive critical equipments like computers & peripherals, medical instrumentation digital communication telemetry systems, CNC Machines etc. and stopping such disturbance generated by the noisy equipments load from being injected into the power line.
