Product Description

PRODUCT INTRODUCTION

Oil-immersed transformers (S11, S13, S20, S22, SH15 series) focus on efficiency. S11/S13 use cold-rolled silicon steel; SH15 (amorphous alloy) cuts no-load loss by 70%; S22 meets GB 20052-2020 Level 1. Corrugated tanks prevent leakage; windings with high-purity copper enhance short-circuit resistance. Sealed (S11/S13) for humid/outdoor use. Compliant with GB1094.1-2013, etc., covering 10/20/35kV, 30-25000kVA, Yyn0/Dyn11. Used in communities, grids; 2-year warranty, lifetime maintenance.

Product Description

Oil-immersed transformer. Its core is made of high-quality, low-loss cold-rolled silicon steel sheets. The high and low voltage windings are precisely wound with high-purity copper wires. Immersed in premium insulating oil, it ensures safety and reliability by providing effective insulation and efficient heat dissipation.

Oil-immersed transformer, with good electrical insulation and excellent heat dissipation from its unique structure, is fire-resistant and explosion-proof. Equipped with an optional cooling system, it operates stably in harsh environments. Suitable for power plants, industrial parks, and urban power grids.
