Product specs
Buyer's Digest
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 S20-series oil-immersed distribution transformer is intended for three-phase power distribution. For the 10–12 kV configuration, the listed high-voltage selections are 10, 10.5, 11, and 12 kV, paired with a 0.4 kV low-voltage side. Available rated capacities are listed from 30 to 2,500 kVA.
High-voltage tapping options are stated as ±2 × 2.5% or ±5%, while impedance voltage is listed as 4% or 4.5%. The transformer uses a core-type, oil-immersed design. Its stated operating principle is electromagnetic induction between primary and secondary windings through the magnetic core.
The product information identifies power and distribution-transformer use and notes that customization is available. Before procurement, buyers should treat the required capacity, exact voltage ratio, tapping arrangement, and impedance as order-specific selections.
Confirm whether the winding configuration described as an autotransformer applies to the quoted unit, since this affects isolation and system design.
Also request the applicable technical drawing, vector group, frequency, insulation level, cooling designation, losses, temperature-rise limits, oil specification, enclosure details, accessories, and installation conditions.
Certification scope, routine and type-test documentation, warranty terms, packaging measurements, delivery schedule, and inspection requirements should be agreed for the exact ordered configuration before approval.
