Optimizing the Design of EE25 and EI28 Transformers: Key Measures to Solve Insulation

Review Design and Layout: Ensure that the transformer winding design meets the operational requirements of the switch-mode power supply, including appropriate insulation levels and winding spacing. Poor design can lead to partial discharge or arcing, which can affect the insulation performance.

Improve Insulation Material Quality: Use high-quality insulation materials, such as standard-compliant electrical paper, insulating varnish, and tape, to enhance the transformer's insulation capability.

Enhance Manufacturing Processes: Ensure strict adherence to operating procedures during manufacturing, including winding, interlayer insulation, varnishing, and baking, to minimize manufacturing defects.

Strengthen Quality Control: Conduct rigorous quality inspections during production, including insulation breakdown tests and insulation resistance tests, to ensure that each transformer meets the specified standards.

Improve Working Environment: Ensure that the transformer is not affected by moisture, dust, or other contaminants in the working environment, as these factors can degrade insulation performance.

Install Protective Devices: Consider installing overvoltage protection devices on the transformer to prevent damage caused by abnormal voltage increases.

Regular Maintenance and Inspection: Perform regular maintenance and inspections of the transformer to identify and resolve potential issues promptly, preventing insulation breakdown.

Select Suitable Transformers: If insulation breakdown issues occur frequently, it may be necessary to consider replacing the transformer with one that has a more rational design and higher reliability.

The company has obtained ISO 9001:2015 and ISO 14001:2015 certifications, IATF16949, and UL certifications, ensuring that its products meet international quality standards.

Golden Eagle has its own dedicated laboratory, capable of conducting various reliability tests from raw materials to finished goods, safeguarding product quality.

With long-term stable and reliable batch quality, the company has attracted a group of loyal major brands that have been placing orders annually since its establishment.

Although the prices are slightly higher by 10-20%, the service life is 1-2 times that of the industry average. The raw material inspection sampling rate is 2-3 times the industry standard. Despite similar manufacturing processes, Golden Eagle's factory has as many as 75 quality control points, making it even more reliable than an insurance company. It is challenging to find another factory with higher quality standards.

Lean production lines with single-piece flow, no accumulation.

Fully automated production from winding, assembly to comprehensive testing.

100% raw materials from well-known enterprises, ensuring material quality from the source.
