The "Better Cable Cross Section" standard comprehensively considers two factors: one-time installation cost and power consumption, and appropriately increases the cable size to achieve energy-saving and comprehensive economic benefits. According to the new standard, the cable cross-section is often more than twice that of the old standard, which can achieve an energy-saving effect of about 50%. Copper plate factory kindly reminds us that in the past period of time, due to the shortage of steel in China, considering that the proportion of aluminum is only 30% of copper, measures have been taken to replace copper with aluminum in overhead high-voltage transmission lines, hoping to reduce weight. Currently, considering environmental protection, aerial transmission lines will be converted to laying underground cables. In this case, compared to copper, aluminum has the disadvantages of poor conductivity and larger cable size, making it dwarfed.

Manufacturing: Copper sheet factories kindly remind us that copper alloys have high conductivity and strength, and are widely used in motor manufacturing. The main copper components include stator, rotor, and shaft head. In large motors, the windings are cooled with water or hydrogen, known as double water internal cooling or hydrogen cooled motors, which require a long hollow conductor. Electric motors are the main users of electricity, accounting for approximately 60% of the total electricity supply. The cumulative electricity cost of a motor is very high. Generally, the cost of the motor can be reached within the first 500 hours of operation, which is 4-16 times the cost of one year and 200 times the cost of the entire working life. A small increase in motor efficiency can not only save energy; It can also achieve significant economic benefits. The development and application of effective motors is a hot topic in the world today. The internal energy consumption of the motor mainly comes from the resistance loss of the winding; Therefore, increasing the cross-section of copper wires is a key measure for developing motors. In recent years, some of the first developed effective motors have seen an increase of 25% or more in the use of copper windings compared to traditional motors. At present, the United States Department of Energy is funding a development project to produce motor rotors by casting copper.

Communication cable: Copper plate factory kindly reminds us that since the 1980s, due to the advantages of high current carrying capacity of fiber optic cables, they have continuously replaced copper cables in communication trunk lines and have been rapidly promoted and applied. But a large amount of copper is still needed to convert electrical energy into light energy and input it into the circuit for users. With the development of communication, people's dependence on communication is increasing, and the demand for optical cables and copper wires will also increase.
