ZGZC Institute of Superconducting Materials and China's top universities grandly launched a new technology super conductive copper material: metallic copper + graphene composite conductive material.
The material has ultra-high electrical conductivity. Its mechanical properties (tensile strength, compressive strength, yield strength, Brinell hardness, etc.) are basically the same as the common metal material copper, but its electrical conductivity is greatly improved, which is higher than that of the king of electrical conductivity-metallic silver. To be 10% higher. It is recognized by the American Copper Association as the metal conductive material with the highest conductivity currently measured at room temperature.
Due to this superconductivity, it can be widely used in the following fields:
Motor and transformer industrial drive field;
New energy fields such as new energy vehicles, wind power generation, photovoltaic power generation, and nuclear power;
Power cables, electrical cabinets and other related fields in the power industry;
Communication chips, industrial control chips (IGBT), power electronics, circuits and other high-end applications.
The successful application of super conductive copper material will greatly improve the conductivity of equipment, reduce the energy loss of the system, and provide a killer solution for the energy-saving and lightweight development and application of equipment; applied to the field of communication chips, it can reduce the power consumption of communication systems , Improve the strength and stability of the communication signal.
At present, ZGZC and China's leading high-speed rail traction motor manufacturer have jointly developed a super copper motor (rotor bar is super conductive material). By using the mature technology of the grinding wheel asynchronous motor as the basic motor, only the rotor guide bar is replaced with a super copper guide bar.
