The most essential difference between the original copper wire and the copper-clad copper wire is the difference in the properties of the conductor material. The original copper is also called oxygen-free copper wire. It is a new copper material modified by technology. It is basically free of impurities, low in oxygen content and high in purity. It is also an ideal wire conductor material in integrated wiring. . The wire made of oxygen-free copper has low resistance, high conductivity and long transmission distance.The difference between original copper and copper-clad copper wire &...

Ultra-high voltage transmission refers to the use of 500 kV - 1000 kV voltage level to deliver electrical energy. If the 220 kV transmission index is 100%, the relative investment per kilometer of EHV transmission, the relative cost per 100 kWh of electricity transmission per kWh, and the consumption of metal materials are greatly reduced, and the utilization rate of the corridor is obvious. improve. In daily life, we can often see overhead EHV transmission projects. Have you ever thought about such a question: Why can't the high-voltage wires be buried underground ...

In 2019, the development of China's photovoltaic industry has come to a critical adjustment period. Not only the development of the whole industry tends to be orderly from “barbaric growth”, but also the entire industry chain needs to complete the all-round transformation of quality, technology and efficiency. At present, in recent years, China's photovoltaic industry has made great progress in technology, technology, efficiency and other aspects, and policy has also begun to focus on reducing the non-technical costs of the industry. It is reasonable to say that the development of the ...

[Cable Network News] In recent years, with the rapid development of the national economy, the demand for special cables has increased dramatically. The demand for special cables in the shipbuilding, railway, aircraft, aerospace, petroleum, chemical, metallurgical and nuclear power industries has increased year by year. Due to the expansion of the entire market capacity, special cables have also ushered in good development opportunities: oil drilling rigs demand more than 15,000 kilometers per year; high-speed rail demand exceeds 37,300 kilometers... and such as railway signal cables, marine ca...
