Energy-Saving Three Phase Oil Immersed Transformer
10kvS10 oil-immersed transformer product advantages
1.More energy-saving: no-load and load loss are lower than S9, and long-term operation electricity costs are lower
2.More durable: fully sealed corrugated fuel tank, the oil does not oxidize, and there is no hanging core maintenance.
3.More stable: strong short-circuit resistance, adaptable to power grid fluctuations, low failure rate
4.Quieter: lower noise, suitable for noise-sensitive scenes such as residential areas and schools
5.Cost-effective: performance close to S11, lower manufacturing cost, suitable for conventional distribution network selection
1.Product Overview
The 10kV S10 series oil-immersed distribution transformer is a nationally certified energy-efficient model, outperforming the S9 series and rivaling the S11 series. As the primary energy-saving solution for urban/rural power grids, industrial facilities, and public buildings, it features a fully sealed design with premium cold-rolled silicon steel sheets and high-conductivity oxygen-free copper conductors. This configuration ensures low energy loss, minimal noise, exceptional reliability, and maintenance-free operation. The transformer reliably converts 10kV voltage to 0.4kV, meeting the demands for long-term, uninterrupted, safe, and efficient power supply.

3. Key Features
1. Significant Energy Efficiency The S10 series demonstrates markedly lower no-load and load losses compared to the S9 series, featuring higher energy efficiency ratings. Long-term operation can substantially reduce power consumption and lower electricity costs.
Fully sealed and maintenance-free design with a corrugated oil tank featuring a fully sealed structure, which isolates transformer oil from air, preventing oxidation and moisture absorption. This eliminates the need for core lifting or oil replacement, significantly reducing maintenance workload.
The coil features robust construction and high mechanical strength, with strong short-circuit resistance. It ensures stable operation and adapts to grid fluctuations and load variations.
The low-noise, low-loss core utilizes premium high-permeability materials and optimized laminating techniques to effectively reduce no-load losses and operational noise, making it ideal for environments requiring quiet operation.
Features long service life and high reliability with stable insulation system, rational heat dissipation design, high-temperature resistance, aging resistance, and low overall operational failure rate, with a service life exceeding 20 years.
Compact in size and easy to install, with optimized structural design, small external dimensions, and moderate weight, it is suitable for various installation environments such as indoor distribution rooms and outdoor box-type substations.
Application Scenarios
1. New Construction and Upgrading of Urban and Rural Power Grids Suitable for 10kV distribution systems in urban residential areas, streets, and rural power grids, serving as the primary equipment for energy-saving upgrades.
Industrial parks provide stable power and lighting for factories, mines, machinery processing, chemical plants, and building materials enterprises.
Commercial and public buildings are applicable to power distribution in locations such as shopping malls, office buildings, hotels, schools, hospitals, and government office buildings.
Infrastructure supporting facilities are suitable for power supply to road lighting, water conservancy, pumping stations, rail transit, communication base stations, etc.
Box-type substations and prefabricated substations can serve as core components of box-type substations, widely used in centralized power supply scenarios such as construction sites, industrial parks, and residential communities.
