Anhui Kesidi Electric Co.,Ltd
S11 Series 20kV/11KV Three-Phase Voltage Conversion Oil-immersed Transformer
S11 Series 20kV/11KV Three-Phase Voltage Conversion Oil-immersed Transformer

Description

This three-phase oil-immersed distribution transformer is with a new insulation structure to improve short-circuit resistance.


The iron core is made of high-quality cold-rolled silicon steel sheets. The high-voltage winding is made of high-quality oxygen-free copper wire and adopts a multi-layer cylindrical structure. All fasteners are treated with special anti-loosening treatment. 


The three-phase oil-immersed distribution transformer has the characteristics of high efficiency and low loss, which can save a lot of electricity consumption and operating costs, and has significant social benefits. It is a high-tech product promoted by country.

Model Designation

The Model Designation of the S11 Series 20kV/11kV Three-Phase Voltage Conversion Oil-immersed Distribution Transformer

Reliable Structure

Based on the traditional structure and mature technology, our company has made many improvements, such as: 


◆ Adoption of spiral coils with longitudinal oil channels for improved internal heat dissipation.

◆ Improved effective support on the coil end face for better resistance to short-circuit current.

◆ Adoption of a new lifting structure and body positioning structure to ensure greater reliability during long-distance transportation and operation.

◆  we also have many unique and reliable structures at your service.


The selection of transformers with higher performance level will have a higher level of technology.
