S22 10kV Oil-Immersed Distribution Transformer (Grade 1 Energy Efficiency)

Product Overview

The S22 series Grade 1 oil-immersed distribution transformer keeps the S20 no-load-loss level and further optimizes load loss to GB 20052-2020 Grade 1 (with GB 1094.1, GB/T 6451 and IEC 60076). For workshops, commercial complexes and data centers running at higher mean load factors, S22 delivers the lowest annual combined loss.

Key Features

• Load loss meets GB 20052-2020 Grade 1 — clear savings in heavy-duty operation;
• Fully sealed corrugated tank, maintenance-free, installation-compatible with S11/S13/S20;
• Strong sudden short-circuit withstand; routine/type test reports included, third-party witness available;
• 50/60Hz and multi-voltage export variants with multi-language nameplates.

Typical Applications

Industrial, mining and oil & gas distribution; commercial buildings and data centers; main intakes where load factor stays above 50%.
