High Abrasion Resistance Magnet Wire

Through technological renewal, the motors are getting smaller, lightweight in size, and more efficient in property. In order to meet these trends Sam Dong has focused on the importance of increasing space factor by inserting more wire into existing slot in motors. Furthermore, these motors (which are improved with space factor) are designed to increase productivity through high speed-winding process as well as their properties. Sam Dong developed High Abrasion Resistance Magnet Wire (SDW-A) to reduce abrasion during winding process and keep insulated property.

Sam Dong’s aim is to help our customers design compact motors with efficiency, and improve the various productions methods and properties of enamel wire during the last 3 years. Consequently, our product SDW-A has 45% of increase for abrasion resistance and it is used in alternator in automobile industry at the moment. Likewise, we are focused at all times on developing products consistent with market trend in order to meet our customers needs.

The Flow of Energy

Sam Dong’s products are transporting and transforming energy, and is related to the flow of the energy with their wire and cable products. From stator coils used in turbine generators for generating electricity to winding coils that you can find in engines, in cars, railway vehicles, and even many home appliances. The shared constituent is that all applications are energy and electricity related.

The Story of OFHC

Copper was the first metal used by human beings.

The discovery of copper, and a flourishing culture where metals were used to make useful implements, led to remarkable developments in human civilization beyond the Stone Age. Still today, the use of copper has great impact on our daily lives. Copper is widely used in the electric energy industry due to its high conductivity and excellent ductility. In terms of thermal and electrical conductivity, only silver has a higher value of conductivity. In the electric energy industry, copper is the primary material used to make Winding Wire. Sam Dong is a world-class producer of OFHC, the preferred metal for the manufacture of Winding Wire.The use of OFHC provides for higher quality Winding Wire due to its much lower oxygen content than Electrolytic Tough Pitch (ETP) copper. OFHC offers higher electrical conductivity, and exhibits a higher recrystallization temperature than ETP. Additionally, due to the fact that it contains a maximum of 10 ppm of oxygen compared to 200 ppm to 600 ppm of oxygen for ETP, the production of copper fines during processing is inherently reduced when using best wire-drawing practices.

Currently, Sam Dong OFHC is being used world-wide in the production of Winding Wire, high voltage transformers, motor winding and electrical power generation products, and as connectors in solar power generation industries.
