CORE: In order to achieve better reduced losses and noise, transformer core is mitered cut from the highest quality cold-rolled grain oriented silicon steel (CRGO). WINDINGS: The HT and LT windings designed in accordance with the temperature rises, insulation and impulse voltage levels, overload conditions, short circuit stresses which are issued in international manufacturing standards INSULATION: Maintain high insulation level of class F as per IEC at the dielectric circuit of transformer which isolate the magnetic and electric circuit and their parts. TANK: Design and construction process of the tank is completed with mild-steel along with oil conservator, radiators and other features to form a complete unit having sufficient strength during heat dispatch under load condition. COPPER: Due to Copper’s inherent high conductivity, ductility and strength, all Transformers are manufactured with pure electrolytic copper only. All transformer comply with following specification:
Installation to be specified for Three-Phase transformer (indoor or Outdoor)
Step down type, (Step-up on request)
Mineral oil immersed
ONAN type natural Cooling
Standard anti corrosion surface treatment and coating
Cover Bolt on tank
WARRANTY: We provide warranty against our product for a period of 12 months from the date of delivery which we get from our vendor that means currently we do not have the capacity of making transformer of our own. But we assure that we source our product from reputed manufacturer and we consult and prefer client choice before delivery. We will repair/replace the defected parts within shortest possible time at our cost. After expiry of the warranty period, repair/ maintenance of the equipment may be carried out for a nominal fee
