Product Features
1、 Voltage conversion function
Transformers can increase or decrease the AC voltage as needed. For example, in the process of power transmission, in order to reduce line losses, the voltage is usually raised in the power plant and transmitted to a distant location through high-voltage transmission lines. Then, at the user end, a transformer is used to lower the voltage to an appropriate value for use by the user.
2、 Electrical isolation function
Transformers can achieve electrical isolation between input and output circuits. This means that there is no direct electrical connection between the two circuits, only energy is transmitted through magnetic coupling. This isolation can improve the safety of the system, prevent faults in one circuit from affecting the other, and also help reduce electrical interference.
3、 Efficient energy transfer
Transformers have high efficiency and can effectively transfer energy between input and output. Generally speaking, the efficiency of transformers can reach over 95% or even higher. This is because transformers mainly rely on electromagnetic induction to work, without mechanical moving parts, reducing energy loss.
4、 Multiple types and specifications
Transformers come in various types and specifications to meet different application needs. According to their purposes, they can be divided into power transformers, instrument transformers, test transformers, and special transformers; According to the number of phases, it can be divided into single-phase transformers and three-phase transformers; According to the cooling method, it can be divided into dry-type transformers and oil immersed transformers. Different types of transformers vary in structure, performance, and applicable scenarios.

V. Selection & Usage Recommendations
Proper transformer selection is cruclal for ensuring the stable operation of the power system. Users are advised to consider the followingfactors comprehensively during selection:
Rated Capacity.Select based on the actual load size, load characteristics, and future expansion margin to avoid long-term overload or underload operation.
Voltage Level: Confirm that the high-side voltage at the connection point matches the transformer’s high-voltage rated voltage.
Installation Environment: Consider the ambient temperature, alttude,humidity, and any speclal corrosion protection requlrements at theinstallation site, as these factors may influence the transformer’s output capability and protection design.
Energy Efficiency Level: S13 represents a specific performance level. Users can evaluate the economics of transformers with diferent efficiencyclasses based on local electricity pricing policies and long-term operating costs.
Correct installation,regular inspections, and preventive testing are significant for ensuring the safe and stable operation of the transformer and extending its service life.
