What are the advantages of oxygen free copper cables?
Oxygen free copper has higher conductivity due to its high purity, low electrical resistivity, good corrosion resistance, and processing performance. These characteristics make oxygen free copper widely used in fields such as power transmission, electronics, electrical and communication industries, ensuring stable current transmission and efficient energy utilization.
Why is oxygen-free copper more conductive?
1.High purity: The copper content in oxygen free copper cables is extremely high, usually greater than 99.95%, ensuring excellent conductivity of the conductor. Among them, the purity of TU1 oxygen free copper reaches 99.99%, and the oxygen content is not more than 0.01%; The purity of TU2 oxygen free copper reaches 99.95%, and the oxygen content is not more than 0.02%.
2.Excellent conductivity: Oxygen free copper has excellent conductivity, with a conductivity of up to 100% IACS and extremely low resistivity, enabling efficient power transmission. This high conductivity minimizes the loss of current during transmission, ensuring efficient utilization of electricity.
3.Good corrosion resistance: The surface of oxygen free copper does not form an oxide layer, so it does not affect the conductivity and also enhances the corrosion resistance of the wire. This enables oxygen free copper cables to maintain stable performance even in humid and corrosive environments.
4.Good processing performance: Oxygen free copper has good ductility and is easy to process into wires of different specifications and shapes, meeting the needs of different fields. Meanwhile, the structure of oxygen free copper is uniform and the crystal is coarse, overcoming the common porous defects in ordinary copper and possessing superior stretchability across all wire diameters.
5.Long service life: Oxygen free copper cables are less prone to heating and have a longer service life. Meanwhile, due to its small resistance, it does not waste electrical energy and is more energy-efficient and environmentally friendly.
6.High temperature resistance: Oxygen free copper cables can withstand high temperatures up to 100 ℃, making them suitable for high-temperature environments and expanding their application areas.
7.Lightweight: Compared to other metal cables, oxygen free copper cables are lighter and easier to install and maintain.
