Most domestic transformer manufacturers are unable to master aluminum welding technology , and a large number of quality problems occur in production, causing many people to talk about aluminum discoloration. The key to the production of aluminum toroidal transformers is to solve welding problems. Any company that can use copper to produce transformer welding problems can solve it; welding tin with tin is an extremely demanding industry problem. Whoever can solve it is extraordinary!

Traditional aluminum connection

method one

Riveting: riveting aluminum and aluminum, or aluminum and copper together

Disadvantages: a. When aluminum is exposed to the air, a dense thin film of aluminum oxide (Al2O3) is immediately formed on the surface. Aluminum oxide is a poor conductor of electricity. When the power is turned on, the riveting point is easy to heat and will burn out. B. Thin aluminum enameled wire; c. Poor riveting performance and low production efficiency.

Way two

Welding: soldering with special flux

Disadvantages: a. The use of flux during welding generates a large amount of smoke to pollute the environment and is harmful to the human body; b. The flux remains on the solder joint, which is corrosive. Over time, the aluminum wire is easily corroded and broken.

Advantages of Hengda Aluminum Wire Transformer

Hengda uses advanced aluminum welding technology and process to perfectly solve the hidden quality problems of traditional aluminum connections. The main advantages of introducing the rigorous aerospace aluminum welding technology into the production of transformers are as follows:

Kangte Group, a leading enterprise in the radio and television industry, has used more than 500,000 aluminum transformers from our factory for a total of ten years from 2005 to 2015. Most of them are still in normal work and the one-year failure rate is strictly controlled at 200PPM Within, it is far less than 2000PPM of copper transformer failure rate of our factory.
On August 10, 2011, Mr. Ramon Romero, Chairman of the Spanish HR Electronics Group, and Mr. Xiang Wei, the Plant Director, successfully signed a strategic cooperation agreement between Chongzhou Hengda and EFITER of the HR Electronics Group for the European market; aluminum transformers have been exported to Europe in large quantities for a long time Many countries, and praised by customers.

The high-speed railway runs for a long time under the condition of micro-vibration. Our factory uses 220-grade aluminum enameled wire (the quality of the paint layer is better than 130-grade copper enameled wire) to wind the primary of this toroidal transformer to ensure long-term safety and reliability of the toroidal transformer.
