Safety performance
The creep resistance of pure aluminum is poor. In long-term use, due to cold and hot cycles, gaps will be created at cable joints, causing an increase in contact resistance between conductors and making contact points prone to heating, making long-term use unsafe. High conductivity alloy conductors effectively solve this systemic problem:
1. Due to the special conductor formula and heat treatment process, the creep tendency of the conductor material caused by thermal compression is greatly reduced. Even if the cable is overheated and overloaded for a long time, it can maintain the stability of the connection. This has been proven through extensive laboratory research and long-term operations in European and American countries. Our company has collaborated with the Shanghai Cable Research Institute (Quality Supervision and Testing Center for Mechanical and Electrical Materials and Special Cable Products) to conduct comparative tests on the compressive creep of copper, aluminum, and LHB (8030) high conductivity aluminum alloy rods. This also proves that the aluminum alloy rods developed and produced by our company have the same compressive creep resistance as copper based materials, far superior to pure aluminum materials.
2. The unique arched interlocking armor structure of the interlocking armor type cable has superior dispersion and lateral pressure performance. It is made of 5000 series high-strength aluminum alloy tape, which is a non-magnetic material and does not produce eddy current loss. It has good heat dissipation and corrosion resistance, is sturdy, tough, and easy to bend. The interior of the armor is smooth, will not cut the insulation, and has excellent shielding and flame retardant properties.
3. Aluminum alloy cables provide various connections and a series of supporting services such as copper/aluminum accessories. Eliminates system defects such as electrochemical corrosion caused by connections between different metals, oxidation or corrosion of metal surfaces resulting in high resistance, simplifying installation and ensuring safe use. Aluminum alloy cables are lightweight, about 50% equivalent to replacing copper cables, and the length of alloy cables of the same quality is nearly twice that of copper cables; For large-span buildings, steel structures can be saved by 15%, and smaller additional loads can improve the safety of the building itself.
Conductivity
Compared with conductors of the same specifications, the conductivity of high conductivity alloy conductors is 62.5% of the commonly used International Annealed Copper Standard (IACS).
At the same volume, the actual weight of aluminum alloy is about one-third of that of copper. According to this calculation, under the premise of meeting the same conductivity performance, the length of high conductivity aluminum alloy cables with the same weight is twice that of copper cables. Therefore, the weight of high conductivity alloy cables is half that of copper cables with the same current carrying capacity. When the cross-sectional area of the conductor of a high conductivity alloy cable is 1.5 times that of a copper core, its electrical performance is basically equivalent, so it can be used as a substitute for copper cables.
High conductivity alloy conductors have excellent conductivity, creep resistance, thermal conductivity, and corrosion resistance.
