S13 Distribution Transformer - China Manufacturers

S13 type three-phase distribution transformer

1. Low loss, fully sealed, non-excitation voltage regulation (5 levels), 24-hour uninterrupted power supply, long annual operating time. 2. Cooling method: ONAN oil-immersed self-cooling. 3. High-permeability cold-rolled grain-oriented silicon steel sheets (0.23mm grade), fully oblique joints, no punching, low noise, low loss. 4. Fully sealed corrugated oil tank: no oil conservator, corrugated plate automatically compensates for oil volume changes; completely isolated from the atmosphere, maintenance-free, prevents oil aging, and extends lifespan. 5. Windings: high-purity oxygen-free copper wire; cylindrical/continuous type, uniform oil channels, strong short-circuit resistance. 6. Applicable scenarios: urban residential areas, commercial complexes, industrial park power distribution rooms; supporting facilities for box-type substations, ring main units, and pole-mounted substations; locations with high requirements for energy saving, maintenance-free operation, and low noise. 7. Standardized design, special requirements can be customized.

Why Choose Our Distribution Transformers?

Advanced Energy-Saving Design

You get exceptional efficiency with our latest core technology. The high-permeability cold-rolled silicon steel sheets reduce no-load losses significantly. Your operational costs drop while performance stays consistent. The fully oblique joint construction eliminates punching damage. This means quieter operation and longer service life for your facility.

Maintenance-Free Operation

Your maintenance budget stays under control. The fully sealed corrugated oil tank eliminates the need for an oil conservator. Temperature changes? The corrugated plates automatically adjust oil volume. You won't deal with oil aging or atmospheric contamination. This design extends transformer lifespan and reduces downtime to near zero.

Robust Construction Standards

We use only high-purity oxygen-free copper wire for all windings. The cylindrical continuous winding design creates uniform oil channels. Your transformer withstands short circuits better than standard models. Strong mechanical strength protects your investment during power surges and fault conditions.

Ideal Applications

Urban and Commercial Settings

Your residential complex needs quiet, reliable power. Our S13 type three-phase distribution transformers operate 20% quieter than national standards require. Shopping malls benefit from 24-hour uninterrupted supply. Industrial park distribution rooms get maintenance-free operation year after year.

Integrated Power Solutions

You can pair these units with box-type substations seamlessly. Ring main units integrate perfectly with our standardized design. Pole-mounted installations become simpler with our compact engineering. Special requirements? We customize solutions to match your exact specifications.

Why Lijie Electric Stands Out

You're partnering with more than a manufacturer. Our 2,000+ employees include 160 engineers with advanced degrees. Two massive production bases ensure capacity when you need it. Annual sales exceeding 5 billion RMB prove our market leadership.

International certifications mean global reliability. CE, UL, and IEC approvals open doors to any market. Our quality control follows GB/T 27922-2021 after-sales standards. Every unit passes National Transformer Quality Supervision testing.
