The D11 single-phase oil-immersed transformer is a crucial power equipment in many distribution networks, especially suitable for applications where single-phase power supply is required. It often adopts a high - quality cold - rolled grain - oriented silicon steel sheet. The core is designed with a stepped - lap joint, which can reduce the magnetic leakage and core loss effectively. This design ensures that the magnetic flux distribution in the core is more uniform, enhancing the overall magnetic efficiency.
This Single-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 Single-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.
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.
