35Kv S11 Series Oil-Immersed Power Transformer

The core is made of high quality cold rolled steel with high purity and uniformity, which can effectively reduce iron loss and noise.


The coil adopts oxygen-free copper with high conductivity and corrosion resistance, which can effectively reduce copper loss and improve the efficiency of the transformer.


The core adopts steel belt tightening and molding technology, which enhances the clamping force of the core and further reduces the iron loss and noise.


The coil adopts block and step electric field distribution, which makes the electric field more uniform and improves the reliability of the transformer.


The inner winding support is strengthened to improve the stability of the transformer, prevent the deformation of the winding, and improve the transformer's ability to resist sudden short-circuit.


In summary, the high-efficiency and low energy consumption transformer made of high-quality cold rolled steel and oxygen-free copper has high performance and reliability, and is an indispensable and important equipment in the power system.

Product Details

First of all, S11 series oil-immersed power transformer adopts high quality raw materials. Its iron core adopts cold-rolled silicon steel sheet with high magnetic permeability, which greatly reduces iron loss and improves the efficiency of the transformer. At the same time, the windings of the transformer are made of high-strength insulating paper and insulating varnish, which ensures the insulation performance and service life of the transformer.


Secondly, S11 series oil-immersed power transformer is optimized in structural design. Its compact structural design makes the transformer cover a smaller area, which is easy for transportation and installation. Meanwhile, the heat dissipation system of the transformer has been improved with advanced cooling technology, which improves the transformer's load capacity and operation stability.





35kv s11 Series Oil-Immersed Power Transformer


In terms of technology, S11 series oil-immersed power transformer adopts advanced production technology. The manufacturing process of its core and winding is strictly controlled to ensure the quality of the transformer. Meanwhile, the assembly and commissioning process of the transformer is also finely managed to ensure the performance index of the transformer.
