Aluminum alloy bus tube conductor advantages
1. The tube bus is produced by forging seamless tube hot-rolled and cold-drawn process, with smooth surface, high dimensional accuracy, large tensile strength, and is not easy to generate discharge and deformation, and low skin effect;
2. The products are made of aluminum alloy, with excellent processing, welding, electrical conductivity and heat resistance functions.
3. Good convective heat dissipation premise, strong electrical conductivity, large load flow, generally can reach 2A/m㎡, than the rectangular bus with equal surface load flow 25% larger;
4. Strong heat resistance, can improve the creep strength and carrying capacity of tubular conductors at high temperature, reduce loss, and improve the safety and reliability of power transmission and transformation system;
5. Small floor space of installation, 1/3 less than that of soft conduction;
6. Anti-erosion, not easy to cover ice, strong disaster resistance, longer service life;
7. Convenient installation, beautiful shape, safe operation, no mess, reliable, easy to inspect and maintain.
Therefore, the Aluminum alloy bus tube conductor has been gradually accepted by the electric power design part and applied in a large number of electric power engineering.In recent years, only in 220 kv to 500 kV transmission and transformation projects, the amount of tubular conductors has been increasing by 25-30% every year.According to the development trend of electric power, tubular conductor, as a new current-carrying conductor, will replace the traditional rectangular, slot, bar-shaped busbar and soft wire with its huge unique wind in lines, power primary equipment, power generation and transformation system and other fields, leading the new trend of electric power materials and showing a huge development space.
