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
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.
