Product Description

The S11 Oil Immersed Distribution Transformer is based on the S9 series. By using oxygen-free copper wire with lower resistivity and undergoing a series of additional surface treatments, the no-load loss is reduced by an average of 30%, and the no-load current is decreased by 70-85% compared to the S9 model. The average temperature rise is reduced by 10K, ensuring more reliable electrical performance and increasing the product's service life by more than double.

Product Feature

The core feature of the S11 oil-immersed power distribution transformer vividly demonstrates the classic design of China's power distribution equipment's transition from high energy consumption to energy-saving type.

The most significant technological breakthrough lies in its core structure design - it is the first to extensively use high-quality cold-rolled oriented silicon steel sheets, combined with full 45° staggered seams and holeless binding techniques.

This design can significantly reduce the magnetic resistance and eddy current losses in the magnetic circuit. Compared with the previous S9 series, the no-load loss has decreased by approximately 30% on average.

At the same time, the windings of the S11 oil-immersed power distribution transformer adopt optimized layered or foil design, combined with the corrugated oil tank to enhance the heat dissipation effect. The load loss also decreases by 15% to 20%. The overall operational efficiency and economy have been significantly improved.

In terms of performance, it inherits the advantages of oil-immersed transformers, such as strong overload capacity and stable heat dissipation, and has lower operating noise.

It can be said that this product is the main force for energy conservation in the replacement of old with new of urban and rural power grids. By reducing long-term operating electricity costs, it achieves excellent total cost of ownership (TOC) throughout the entire life cycle.

The Advantage of S11 Oil-immersed Power Distribution Transformer

The advantages of the S11 oil-immersed transformer are rooted in its oil-paper insulation technology system. The core advantage lies in its unparalleled power carrying and heat dissipation capabilities.

The high specific heat capacity and circulation characteristics of the insulating oil give the S11 oil-immersed transformer excellent overload and shock load resistance, enabling it to dominate in the large-capacity (up to millions of kVA) and high-voltage fields.

At the same time, the mature oil-paper insulation system has a long lifespan, low initial purchase cost, and can achieve precise internal fault prediction through oil chromatography analysis (DGA).

This transformer is essentially a solution designed for outdoor, remote suburban, and other spaces with ample space and controllable fire risks for power stations and power grids.
