Product Introduction

The YAWEI S11-1600kVA oil immersed distribution transformer is designed for three-phase power distribution systems requiring voltage conversion from 10kV to 0.4kV. With a rated capacity of 1600kVA and a Dyn11 vector group, it is suitable for industrial facilities, commercial power networks, and infrastructure projects.

This model is specified with all-copper windings and Karamay No. 25 transformer oil. Its configuration includes an oil conservator, cable box, and terminal box. The transformer is finished in B05 sea gray and specified with WTHF2 corrosion protection. The project also requires an additional 10% reserve transformer oil and an 820mm track gauge.

The transformer is manufactured according to the confirmed technical requirements and approved drawings. Final specifications, nameplate details, accessories, and documentation should be verified before production to ensure consistency with the customer's requirements.

1. 1600kVA Capacity for Three-Phase Distribution

The S11-1600kVA transformer has a specified rated capacity of 1600kVA, with a 10kV high-voltage side and a 0.4kV low-voltage side. Its Dyn11 vector group is commonly used in three-phase distribution applications where the system requires a star-connected low-voltage winding with a neutral terminal.

The final voltage ratings, tap settings, impedance, and connection details should match the approved project specification.

2. All-Copper Windings and Transformer Oil

This project specifies copper windings for both the high- and low-voltage sides. Copper winding construction is selected according to the electrical and thermal requirements of the project.

The specified insulating liquid is Karamay No. 25 transformer oil. An additional quantity equivalent to 10% reserve oil is included in the project requirements. The final oil grade, quantity, and accompanying documentation should be confirmed in the order specification.

3. Conservator Tank and Cable Connection Configuration

The transformer is specified with an oil conservator, cable box, and terminal box. These components support the project's oil-system arrangement and cable connection requirements.

The detailed cable entry arrangement, terminal layout, accessory ratings, and installation clearances should be confirmed in the approved drawings before manufacturing.

4. Corrosion Protection and Project-Specific Design

The specified corrosion protection classification is WTHF2, and the requested exterior color is B05 sea gray. The transformer also has a specified track gauge of 820mm.

YAWEI can prepare technical drawings and documentation for customer review before production. The approved drawings and technical requirements should be used as the reference for manufacturing, inspection, and final nameplate preparation.

Installations with a defined track gauge and cable connection arrangement

Review the approved drawings: Verify voltage ratings, tap range, vector group, impedance, cable box layout, terminal box arrangement, and track gauge before installation.
Inspect the transformer: Check the tank, conservator, bushings, cable box, terminal box, and other accessories for transport damage.
Confirm oil requirements: Verify the specified transformer oil grade and ensure the reserve oil is stored and handled according to the manufacturer's instructions.
Check the installation foundation: Confirm that the foundation and track arrangement accommodate the specified 820mm gauge.
Verify electrical connections: Check the high- and low-voltage connections, neutral connection, grounding, and protection devices against the approved electrical design.
Complete pre-energization checks: Perform the required inspections and electrical tests in accordance with the manufacturer's instructions and applicable standards.
Maintain the transformer regularly: Inspect oil level, leakage, bushings, connections, and accessories at the intervals recommended by the manufacturer.

Installation and commissioning should be performed by qualified personnel. The approved technical documentation takes precedence over general guidance.

>> FAQ

How long do Yawei transformers last?

Built for 40 years with routine care. Quality core materials and winding techniques keep thermal stress low, extending insulation life beyond typical industry averages.
What upkeep is needed?

Check oil level/temp daily; test oil annually; inspect bushings and seals yearly; perform major filtration every 5 years; replace dial gauges at decade intervals.
How does it work?

AC in the primary creates a varying magnetic field in the core, inducing voltage in secondary coils. Our split design gives two separate 0.6 kV outputs from one 10 kV input.
How to pick the right model?

Match primary/secondary voltages and kVA to your load; consider cooling, altitude, and ambient range. Our Dy11d0 type excels with harmonic‑heavy loads like VFDs.
Why choose Yawei transformers?

Over 31 years in business, 240 k m² facility, IEC/IEEE compliance, full customization, 2.5 billion RMB annual sales, and proven reliability in utilities and industry worldwide.
