Product Description: 

The S20-M-10 series 10kV fully sealed oil-immersed distribution transformer is a mainstream energy-saving standard model for power grid construction. It is a Level 2 energy-efficient product specifically designed for urban and rural distribution network upgrades, industrial power distribution, commercial building power supply, and new energy power plant applications. Through core material upgrades and structural optimization, this series significantly reduces operating losses while ensuring high reliability and long service life, resulting in substantial energy savings and lower total cost of ownership. The product adopts a fully sealed corrugated oil tank structure, eliminating the need for an oil conservator and isolating the insulation system from air and moisture corrosion, thus delaying insulation aging and achieving maintenance-free operation and maintenance, significantly reducing user operating costs. Simultaneously, the product possesses core advantages such as low noise, strong short-circuit withstand capability, and wide adaptability, flexibly adapting to different installation environments and usage requirements, making it the optimal choice for current distribution network construction that balances cost-effectiveness and energy efficiency.

Normal Environmental Conditions:

4.Installation Environment:

Outdoor locations free from flammable and explosive materials, severe impact and vibration, and strong electromagnetic interference. Can be installed on poles, platforms, transformer substations, or indoor distribution rooms, suitable for unattended installation scenarios.

5.Power Supply Conditions:

Rated frequency 50Hz/60Hz, rated voltage 10kV, voltage fluctuation within ±5%, suitable for power grid environments containing a small amount of harmonics.

6.Operating Mode:

Can operate continuously at 100% rated load for extended periods.

Model:

S: Represents a three-phase transformer (Three-phase) Transformer is the most widely used transformer type in distribution network systems.

20: Represents a performance level code, with no-load loss reduced by approximately 15% compared to the S13 series.

M: Represents a fully sealed structure, employing a corrugated tank design that eliminates the need for an oil conservator, completely isolating the insulating oil from air and moisture corrosion, achieving maintenance-free operation.

10: Represents a rated voltage level of 10kV, the most critical distribution network voltage level in urban and rural power distribution, industrial power distribution, and commercial buildings. Customizable voltage levels within the 6-11kV range are also available.
