S22 type power transformer

S22 Type Power Transformer: Advanced Energy-Efficient Distribution Solution 

The S22 type power transformer from Lijie Electric Power Technology Group delivers exceptional Level 1 energy efficiency performance. With no-load loss reduced by 20% compared to S13 models and load loss decreased by 10-15%, you'll see immediate operational savings. Our transformers feature 0.23mm high-permeability grain-oriented silicon steel cores and oxygen-free copper windings, ensuring reliability across 30-3150kVA capacity range. Backed by our 500,000 square meter manufacturing facility and 160+ engineers, we provide enterprise-grade solutions meeting ISO 9001:2015, CE, UL, and IEC standards with 6-30 day customization cycles.

Why Choose Our Energy-Efficient Distribution Transformers?

Superior Energy Savings

Your electricity bills matter. Our transformers use advanced core technology with five-stage step joints and non-overlapping yoke processes. This design reduces energy waste considerably compared to older models.

The foil-type low-voltage coil construction minimizes heat generation. You get more power delivered where you need it, with less lost to resistance.

Reliable Performance You Can Trust

We build transformers that work day after day without interruption. The fully sealed oil-immersed design means minimal maintenance requirements for your facility.

Your operations stay running smoothly. Our ONAN self-cooling system handles thermal management automatically, requiring no external intervention.

Flexible Configuration Options

Every project has unique requirements. We offer both Yyn0 and Dyn11 connection groups to match your specific application needs.

Choose from 6kV or 12kV voltage ratings. Select single-phase or three-phase configurations. Need special tap ranges? We provide ±5% or ±2×2.5% options to optimize voltage regulation.

Technical Specifications

Key Technical Advantages

Advanced Core Technology

We use 0.23mm high-permeability grain-oriented silicon steel sheets in our core construction. This premium material choice directly impacts your bottom line through reduced no-load losses.

The five-stage step joint design optimizes magnetic flux distribution. Combined with our non-overlapping yoke process, you benefit from approximately 40% lower no-load loss compared to S11 models.

Optimized Winding Design

Our oxygen-free copper wire construction ensures maximum conductivity. The foil-type low-voltage coil configuration reduces load loss by approximately 10% versus national standards.

Optimized ampere-turn balance minimizes stray losses. Your S22 type power transformer operates more efficiently under all load conditions.

Enhanced Structural Engineering

We've optimized the leakage flux path throughout the design. This reduces losses in both the oil tank and structural components.

The fully sealed construction protects internal components from environmental contamination. You get longer service life with fewer maintenance interventions required.
