S22 type 20kV power transformer

S22 Type 20kV Power Transformer: Enterprise-Grade Energy Solution

When you need reliable power distribution for critical infrastructure, the S22 type 20kV power transformer from Lijie Electric delivers industry-leading performance. Manufactured at our 500,000 square meter facilities by a team of over 160 specialized engineers, this transformer achieves GB 20052 Level 1 Energy Efficiency with no-load losses 40% lower than S11 models and 20% below S13 standards. Our capacity range spans 30-2500kVA, featuring ONAN oil-immersed self-cooling and Dyn11 connection groups. With production cycles of 6-30 days and certifications including ISO 9001:2015, CE, UL, and IEC compliance, we serve power grids across 15+ countries with proven reliability.

Why Choose Our 20kV Distribution Transformer?

You're looking for more than just equipment. You need a partner who understands power infrastructure challenges.

Our transformers feature fully sealed construction that eliminates maintenance headaches. You won't need to worry about oil leaks or environmental contamination. The off-grid voltage regulation system ensures your operations stay safe during adjustment procedures.

Energy savings translate directly to your bottom line. With load losses 10-15% lower than national standards, this transformer pays for itself through reduced electricity costs. Many facilities see noticeable reductions in monthly power expenses within the first year.

The near-elliptical coil design with integral assembly provides exceptional short-circuit resistance. Your transformer keeps running even under sudden electrical stress. We've engineered uniform axial clamping force throughout the coil structure, so you get consistent performance year after year.

Frequently Asked Questions

What makes the S22 series more efficient than older models?

The product uses advanced core materials and optimized winding techniques. This combination dramatically reduces both no-load and load losses compared to S11 and S13 predecessors.

Can you customize specifications for unusual requirements?

Absolutely. While we offer standardized designs, our engineering team regularly adapts transformers for unique voltage requirements, environmental conditions, or space constraints. Share your specifications and we'll develop a solution.

How long does typical installation take?

Most installations complete within 1-2 days once the transformer arrives on site. We provide detailed installation guidance and technical support throughout the process.

What documentation comes with each unit?

You receive complete technical drawings, operation manuals, factory test reports, and all relevant certification documents needed for regulatory approval in your region.

Do you provide spare parts?

Yes. We maintain inventory of critical components and ship replacement parts globally. Our after-sales team assists with any technical issues that arise.

Is training available for maintenance staff?

While the fully sealed design requires minimal maintenance, we offer technical training for your team covering operation procedures, troubleshooting, and safety protocols.
