Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Distribution Transformers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This 11 kV, 500 kVA three-phase oil-immersed transformer is presented for outdoor electrical power distribution. The listed S11 design uses a core-type, two-winding construction and operates at power frequency.
The broader product series is described as fully sealed, using a corrugated oil tank whose elastic movement compensates for changes in oil volume without an oil conservator. This arrangement is intended to isolate the transformer oil from ambient air and slow oil deterioration and insulation aging.
The series information lists 50 Hz or 60 Hz configurations, single- or three-phase versions, and off-circuit or on-load voltage regulation. Listed tapping options include ±5%, ±2 × 2.5%, and ±4 × 2.5%. Connection symbols include Dyn11 and Yyn0, with other requested configurations also indicated as available.
These are series-level options and should not be assumed to describe the supplied 11 kV, 500 kVA unit until they appear on an approved technical schedule. The stated standard operating conditions are an altitude not exceeding 1,000 m and ambient temperature not exceeding 40°C.
The product information indicates that parameters may be adjusted when site conditions fall outside those limits.
Before ordering, the buyer should confirm the complete primary and secondary voltage schedule, vector group, frequency, tap changer type and range, short-circuit impedance, insulation requirements, cooling designation, temperature-rise limits, losses, sound limits, enclosure details, terminals, accessories, and required tests.
The installation altitude, minimum and maximum ambient temperatures, seismic or environmental exposure, applicable local standards, and interface with protection equipment should also be documented.
Request an approved drawing, nameplate schedule, routine test documentation, and final packing dimensions and weight for the exact configured unit, because the available dimensional and packaging data may not correspond specifically to the 500 kVA configuration.
