Product introduction
Three Phase Oil Immersed transformer is a key equipment in the power transmission and distribution system. Its core role is to realize the conversion of electrical energy of different voltage levels and ensure the stability and economy of electricity in long-distance transmission and terminal use.The product is made of high-quality insulating oil and iron core materials, with excellent heat dissipation performance and overload resistance. It is equipped with a temperature monitoring sensor for oil-immersed transformer that can monitor oil temperature changes in real time and feedback the operating status of the equipment in a timely manner. It cooperates with the oil quality detection component to ensure the stable performance of the insulating oil, effectively extend the service life of the equipment, and is widely adapted to various industrial and civil power projects.

Model Meaning

Product Features
- High efficiency and energy saving: the use of low-loss silicon steel sheet iron core and high-quality winding coils to reduce no-load loss and load loss, high energy conversion efficiency, in line with national energy-saving standards, long-term use can significantly reduce power consumption costs.
- Excellent heat dissipation: relying on the immersed oil-cooled heat dissipation structure and the optimized design of the heat dissipation pipe, the heat dissipation area is large and the heat dissipation efficiency is high. It can quickly export the heat generated during the operation of the equipment to ensure the stable operation of the equipment under rated load and strong overload resistance.
- Strong stability: the iron core adopts a multi-stage stacking process to reduce hysteresis loss and noise, the winding is vacuum-dried, and the insulation performance is reliable; the shell adopts a sealed design, which has good dust-proof, moisture-proof, and anti-corrosion properties, and is suitable for complex outdoor environments.
- Convenient operation and maintenance: The equipment is equipped with complete monitoring and protection devices. In addition to the core temperature and oil quality monitoring, it also has functions such as gas protection and overcurrent protection, which can automatically warn and deal with faults; at the same time, a convenient maintenance interface is reserved to facilitate later maintenance and maintenance.

Product Applications
- Industrial field: Suitable for large industrial enterprises such as metallurgy, chemical industry, mining, machinery manufacturing, etc., to provide stable voltage conversion services for production lines and large-scale equipment to ensure continuous power supply for industrial production.
- Power engineering: It is used in power infrastructure such as power plants, substations, and distribution stations to realize step-down conversion of high-voltage power and meet the power distribution needs of urban power grids and rural power grids. It is the core hub equipment in the power transmission link.
- Civil and commercial fields: adapt to residential areas, commercial complexes, office buildings and other places, convert high-voltage grid electrical energy into low-voltage electrical energy suitable for terminal electrical appliances, and ensure the normal electricity consumption of residents' lives and commercial operations.
- Special scenarios: After customized design, it can be applied to power projects in special environments such as plateaus, high humidity, and dust, such as power supply in plateau pastoral areas, and power distribution in industrial parks in coastal areas. It has a wide range of environmental adaptability.
