Invention patent certificate
Utility model certificate, intellectual property specification, invention patent
After years of unremitting efforts and absorption of foreign advanced technology, the company successfully launched the only high-tech power cable with independent patents on key technologies in China. With new aluminum alloy material as conductor, flame retardant silane crosslinked polyethylene as insulation and its unique self-locking armored structure, it has the advantages of low smoke, halogen-free, flame retardant, safety, stability, economy, convenient installation, energy saving and environmental protection. At present, Anhui Xinyi Cable Co., Ltd. has applied to China National Intellectual Property Administration for 49 patents, including 4 inventions of aluminum alloy conductor material, flame retardant material, ultra-soft aluminum alloy conductor and its preparation method, 7 utility model patents such as flame retardant cable, and the remaining 38 patents have entered the substantive examination stage.
Product innovation
Aluminum cable is an advanced and mature technology and product, which has been successfully applied in North America for more than 40 years. The Ministry of Housing and Urban-Rural Development, Ministry of Science and Technology, State Grid, China Southern Power Grid, State Fire Bureau, Sinopec, Datang Electric Power, Ministry of Railways and other departments have widely recognized the use of this new technology in China. The safety performance, electrical performance and mechanical performance of aluminum alloy power cable have been tested by relevant state departments, and all meet the requirements of national standard (GB).
Material innovation
The conductor is made of aluminum alloy and independently developed according to American standards. It has the characteristics of high elongation, easy bending, low resilience, corrosion resistance, creep resistance and stable connection, which greatly improves the defects of pure aluminum, and its mechanical properties and service life are better than those of copper wires, thus achieving the purpose of replacing copper with aluminum.
technological innovation
1. Compaction and stranding technology makes the compaction coefficient reach 0.93, effectively reducing the outer diameter of conductor, improving electrical performance and reducing the cost of cable accessories;
2. Annealing process, using new annealing equipment, the annealed aluminum alloy conductor has better electrical and mechanical properties;
3. The metal interlocking armoring technology is easy to bend, resistant to compression and impact, convenient to install, and can be directly buried in the ground without laying pipelines, thus improving the flame retardancy and fire resistance of cables.
