6063 Aluminum tubular bus bar

Most of the aluminum tubular bus bar of high-voltage and ultra-high-voltage power distribution devices use conventional 6063 alloy. This aluminum alloy has a medium (σb≥205Mpa), and the electrical and physical properties can meet the needs of use. 6063 Aluminum tubular bus bar

6063 Aluminum tubular bus bar

Smooth surface, beautiful appearance, uniform size

mainly used in the conductor connection between power grid transmission wires and substation transformers in my country's power construction projects, jumpers in transmission lines, connecting conductors in power equipment, and large current DC ice melting devices as overcurrent conductors. It replaces traditional the new conductors of rectangular, trough-shaped, rod-shaped busbars and flexible wires are one of the key equipment (materials) in the power transmission and transformation system, which is vital to the safe and reliable operation of the transmission and transformation system and power equipment effect.

Application of 6063 Aluminum tubular bus bar:

6063 Aluminum tubular bus bars are widely used as overcurrent conductors in 220 KV, 500 KV, 750 KV, 800 KV and 1000 KV substations and converter stations in power companies, as well as in high current DC ice melting devices. The product is manufactured by meticulous ingredients, hot-top casting at the same level, horizontal piercing hot rolling, thermomechanical treatment, multi-pass cold drawing and other processes. The market share of this product has remained in the leading position for many years.
