Oil-Immersed Power Transformer (Aluminum)

Best fit

For industrial parks, utility substations, factories and distribution rooms, when the project needs a project-ready oil-immersed transformer with capacity configuration of 30-2500 kVA. What it does:

Oil-Immersed Power Transformer (Aluminum) steps medium-voltage power down for stable distribution while using oil insulation and cooling for long operating cycles. It supports voltage options including 10/0.4kV and 35/10kV. The product is positioned for procurement teams that need clear model selection, technical confirmation and export project coordination. Why buyers choose it:

  • Available capacity configuration of 30-2500 kVA helps match common project loads without changing the product family.
  • Selectable voltage options including 10/0.4kV and 35/10kV supports coordination with site distribution systems.
  • model reference S11/S13 Series (Aluminum), Silicon Steel, ONAN cooling gives engineers a clear basis for technical comparison and specification review.
  • The product can be coordinated with Longxiang switchgear, transformer, new-energy equipment or project accessories for packaged delivery.
  • Product data support clearer communication for overseas tendering, distributor quotation and technical review. Before quotation:

Please confirm capacity, primary and secondary voltage, frequency, vector group, impedance, loss requirement, cooling method, accessories, quantity and destination country.
