R-type single-phase transformers

Three-phase R-type transformer: its iron core system uses a wide range of good orientation cold-rolled silicon steel strips rolled into a waist round, and the cross-section is round, without cutting can be wound. Therefore, the transformer can be manufactured without noise, small magnetic leakage, small no-load current, low iron loss, and high efficiency. The coil is cylindrical, and each circle of copper wire length is short, so the internal resistance is small, low copper consumption, low-temperature rise, overload fluctuation is small, burst than toroidal transformer is better. In addition, the primary and secondary coils are wound separately with a skeleton made of flame-retardant PBT engineering plastics, which results in high electric resistance and good flame retardancy.
R-type transformers can be used as power transformers or isolation transformers for all electrical appliances.
1. It is characterized by high efficiency, small size, and lightweight.
The material used for the R-type iron core is a high-grade cold-rolled oriented silicon steel sheet. After the core is wound, it is annealed to rearrange the molecular structure of the silicon steel sheet.
2. R-type transformer is small in size and light in weight.
R-type transformer has no cutting core winding, using oriented high-grade silicon steel sheet, so the volume is small. Lightweight (30% smaller, 40% lighter, 40% thinner than EI-type transformer).
3. R-type transformer high efficiency.
Due to the core without cutting, iron loss is very small. It uses high-quality materials and a compact structure, the distance between the iron core and the winding is very low, so the efficiency can reach more than 90%.
4. R-type transformer leakage magnetism is small.
R-type transformer core has no magnetic gap and the winding is balanced, so the magnetic leakage is small. Without designing any anti-magnetic leakage measures.
5. R-type transformer without noise and small heat generation.
Because an R-type transformer has no cutting core winding, using the orientation of high-grade silicon steel sheet made of uniform circular cross-section and continuous winding, resistance loss and heat production are very low. And it is not cut, so the magnetostrictive stress is easily absorbed and applied without noise.
6. R-type transformer excitation current is small.
R-type transformer design is reasonable, so it has the characteristics of low iron loss, low heat generation, low excitation current, and energy saving.
7. R-type transformer has a high safety coefficient.
