Product Introduction

The YAWEI S13-M-2000kVA oil immersed distribution transformer is designed for medium-voltage power distribution systems requiring voltage conversion from 10kV to 0.4kV. With a rated capacity of 2000kVA and a Dyn11 vector group, this three-phase transformer is suitable for industrial facilities, commercial buildings, utility distribution networks, and other applications requiring a stable low-voltage power supply.

The oil-immersed design supports electrical insulation and heat dissipation during operation. The transformer can be configured according to project requirements, including confirmed voltage ratings, tap settings, winding materials, cooling arrangements, and applicable technical standards.

YAWEI provides transformer manufacturing and technical documentation support for overseas customers, distributors, contractors, and engineering projects. Final production specifications, nameplate details, and drawings should be confirmed before manufacturing.

1. 2000kVA Capacity for Distribution Applications

With a rated capacity of 2000kVA, the S13-M transformer can serve industrial loads, commercial power distribution systems, and medium-voltage substations. The 10kV primary and 0.4kV secondary configuration is intended for applications that require conversion to a low-voltage distribution supply.

The final capacity selection should account for the project's load profile, starting currents, load growth, and operating conditions.

2. Oil Immersed Insulation and Cooling

The oil-immersed structure uses transformer oil for insulation and heat transfer. The tank and cooling arrangement should be designed to meet the specified temperature-rise limits and installation conditions.

Oil type, cooling method, accessories, and tank configuration can be confirmed according to the approved technical specification.

3. Dyn11 Vector Group

The Dyn11 connection provides a delta-connected high-voltage winding and a star-connected low-voltage winding with a neutral terminal. This configuration is commonly used in three-phase distribution applications where a neutral is required on the low-voltage side.

The vector group must be checked against the project's system grounding, protection, and parallel-operation requirements before ordering.

4. Project-Specific Manufacturing and Documentation

YAWEI can coordinate technical drawings, nameplate information, and manufacturing documentation according to the confirmed order requirements. Customers should review the rated voltage, tap range, vector group, impedance, winding materials, losses, and other specified parameters before approving production.

The final nameplate and technical documents should match the actual transformer configuration supplied.

>> Product Uses

1.Urban Power Distribution Networks

Widely adopted in city substations and residential complexes to step down 10kV to 400V for daily consumption. The oil-cooled design ensures silent operation (≤55dB) ideal for densely populated areas while meeting strict urban safety regulations.

2.Industrial Power Systems

Essential for manufacturing plants, mining operations and assembly lines requiring stable medium-voltage distribution. Its 150% overload capacity reliably supports heavy machinery startups and production peak loads.

3.Renewable Energy Integration

Commonly installed in solar/wind farms as grid-connection transformers. Special anti-corrosion treatment protects components in coastal/high-humidity environments, maintaining 98% efficiency despite renewable power fluctuations.

4.Rural Electrification Projects

Perfect for remote villages due to minimal maintenance requirements. Operates reliably in extreme conditions (-30°C~50°C) with automatic voltage regulation (±3%) for areas with unstable grid supply.

5.Critical Infrastructure Support

Deployed in hospitals, data centers and transportation hubs where power continuity is vital. The hermetically sealed tank prevents oil leakage, achieving IP55 protection for indoor/outdoor installations.

>> FAQ

What is the typical lifespan of your transformer?

Our transformers are designed for a 40-year service life with proper maintenance. Using premium materials and advanced manufacturing processes ensures long-term reliability even under demanding operating conditions.
What maintenance does it require?

Routine checks include oil level/temperature monitoring and insulation testing. The sealed tank design minimizes maintenance needs - we recommend annual inspections for optimal performance.
How distribution transformer work?

Core Components
Primary coil receives high-voltage input (e.g. 10kV)
Secondary coil delivers low-voltage output (e.g. 400V)

Operating Principle
Electromagnetic induction transfers energy between coils via a laminated steel core, stepping down voltage while maintaining power (typical efficiency >98%).

Key Features
Magnetic core concentrates flux for optimal performance
No moving parts ensure silent operation
Oil insulation enhances heat dissipation
How to select the right transformer?

Consider:
Load characteristics
Voltage ratio & power rating
Impedance & efficiency class
Phase configuration
Cooling type (ONAN, ONAF, OFAF)
