Product Introduction
Hozee Electric has independently developed the "Low Loss Winding Optimization Algorithm". By elaborately designing the winding arrangement, the 50kva Single Phase Transformer effectively mitigates magnetic leakage, achieving a 25% reduction in leakage flux compared to traditional products. This improvement further lowers eddy current losses and hysteresis losses. In comparison, this 50kva Single Phase Transformer can cut down no-load current by 30% and reduce noise by 5-10dB. Adopting high-quality materials and strict quality control measures, our transformer boasts advantages of low loss, low noise, high energy efficiency, strong mechanical strength, impact resistance, and easy installation & maintenance, winning unanimous recognition from customers.

Transformer Process Flow Diagram
The production process of our single phase transformers follows strict international standards, covering core stamping, winding manufacturing, coil assembly, vacuum drying, overall assembly, insulation testing, load testing, and finished product inspection. Each process is equipped with professional testing equipment and technical personnel to ensure product quality.
Transformer drawings
Engineers at Hozee Electric design high-quality transformer drawings based on customers' customization requirements, covering key parameters such as high voltage, low voltage, impedance, no-load loss, and load loss. The drawings are provided in both 2D and 3D formats, facilitating customers' installation and construction.
Coil
According to customer requirements, we use high-quality electrolytic aluminum foil and enameled aluminum wire for winding. This material selection effectively reduces production costs while meeting the required performance indicators of the transformer, achieving a balance between cost-effectiveness and reliability.
Assembly of single-phase transformer
The assembly process of single-phase transformers adheres to precise operational standards. We adopt modular assembly methods to ensure the accuracy of each component connection. After assembly, strict air tightness testing and overall performance testing are conducted to ensure the transformer can operate stably in various environments.
FAQ
Q: How to ensure that the transformer has a rated voltage output?
A: Voltage fluctuations may lead to the transformer failing to output the rated low voltage, affecting its normal operation. The solution is to install a tap changer on the transformer to adjust the voltage output. It is important to cut off the input power supply before operating the tap changer to ensure operational safety.
Q: What are the key points for daily maintenance of transformers?
A: Daily inspections for oil-immersed transformers should be conducted once a day, focusing on oil temperature and oil level. Cleaning should be performed monthly or quarterly, and regular tests such as insulation resistance testing, winding DC resistance testing, and oil quality testing should be carried out annually. In special cases such as harsh environments or high loads, the maintenance cycle should be shortened accordingly.
Q: Precautions for transformer installation?
A: The installation position requires a flat and sturdy foundation capable of bearing the weight of the transformer. There should be no flammable or explosive materials in the surrounding area, with good ventilation and easy access for maintenance. Sufficient operating space should be reserved on both the high-voltage and low-voltage sides, and the lead connections must be firm to avoid loosening and overheating. For outdoor transformers, rainproof and sunshade facilities should be installed according to actual conditions to prevent environmental factors from affecting operation.
Q: What is the normal temperature range during transformer operation?
A: The top oil temperature of oil-immersed transformers generally does not exceed 85℃, with a maximum limit of 95℃. The winding temperature of dry-type transformers usually does not exceed 110℃. The upper temperature limit may vary for different insulation levels (such as Class F and Class H), and reference should be made to the nameplate markings. If the temperature exceeds the limit, the load and cooling system should be inspected immediately.
