Reliable Power Distribution Performance

Each transformer is fabricated from high-grade CRGO silicon steel with copper windings and Class A or F insulation, ensuring efficient energy transfer and superior reliability. The design complies with internationally recognized standards like IS 1180, IS 2026, and IEC 60076, guaranteeing consistent operational excellence. With impedance voltage between 5% and 7%, these units support stable grid operation and protect downstream equipment.

Customizable and Durable Engineering

Our transformers are available in both pole and pad-mounted options, tailored to meet specific application needs. The use of mineral insulating oil (IS335/IEC60296) and an epoxy/PU corrosion-resistant paint finish maximizes durability, even in demanding environments. Accessories such as a conservator, silica gel breather, and optional Buchholz relay facilitate optimal maintenance and protection over years of service.

Advanced Safety and Protection Features

Safety is enhanced through IP23 protection (if requested), porcelain or polymer bushings, and double winding coil structures for robust electrical insulation. The incorporation of ONAN cooling supports reliable operation in temperatures up to 50C. Tap changers (manual or automatic) enable voltage boosting, ensuring stable output in variable load conditions and increased transformer longevity.

FAQs of Oil Filled Distribution Transformer:

Q: How is the mounting type for these distribution transformers decided?

A: Transformers can be provided as pole-mounted or pad-mounted based on site infrastructure, available space, and application requirements. Our team guides users in selecting the optimal configuration to ensure easy installation and reliable operation.

Q: What is the process for customizing output voltage or capacity?

A: We offer transformers with outputs and dimensions customized as per client requirements. Customers specify rated voltage (11/22/33 kV) and capacity (162500 kVA) during inquiry, and our engineering team designs the optimal transformer to meet those operational needs.

Q: When is the IP23 protection grade recommended?

A: IP23 protection, available on request, is ideal for installations exposed to dust and limited water ingress. It provides suitable environmental resistance for certain outdoor or semi-enclosed settings, upon assessment of site-specific risks.

Q: Where are these transformers commonly used?

A: Oil filled distribution transformers of this type are widely employed in utility substations, commercial complexes, manufacturing plants, and large-scale infrastructure projects to distribute electricity from high-voltage lines to usable voltages efficiently and safely.

Q: What are the advantages of using mineral insulating oil as per IS335/IEC60296?

A: Mineral insulating oil, certified to IS335/IEC60296, assures superior dielectric strength and thermal stability, which enhance transformer cooling efficiency, electrical insulation, and operational life. This oil also facilitates reliable operation under varied loads.

Q: How does the efficiency above 98% benefit users?

A: High efficiency reduces power loss during transmission, lowers operational costs, and increases sustainability. Users benefit from minimal energy wastage and consistent power delivery, making these transformers both cost-effective and environmentally friendly.

Q: What safety features are included with these transformers?

A: Key safety features include Class A or F insulation, robust bushing options (porcelain or polymer), Buchholz relay (optional) for early fault detection, and conservator systems for effective oil management. Epoxy/PU painting and corrosion resistance further extend service life.
