6063G Tubular Busbar (high-strength Aluminum Alloy Tubular Busbar, Heat-resistant Aluminum Alloy Tubular Busbar)
Product Spotlights
The tubular busbar is one of the key equipment (materials) in the power transmission and transformation system, playing a crucial role in ensuring the safe and reliable operation of the system and power equipment. Its main applications include conductor connections between power grid transmission conductors and substation transformers in China's power construction projects, jumpers in transmission lines, connecting conductors in power equipment, and as overcurrent conductors in high-current DC de-icing devices.
The company's latest development, the 6Z63 (6063-Zr) high-strength heat-resistant aluminum alloy tubular busbar, has obtained a national invention patent (patent number: ZL 2017 1 1110848.X) and has been recognized as a significant scientific and technological achievement in Hubei Province, receiving the third prize for scientific and technological progress in the province. This product incorporates rare earth and rare metal zirconium. Besides possessing the advantages of conventional tubular busbars, more importantly, the 6Z63 (6063-Zr) high-strength heat-resistant aluminum alloy tubular busbar can operate safely at higher working temperatures (150°C-200°C). Its high-temperature (250°C) softening mechanical properties (tensile strength) can maintain over 88% of its room temperature value, reaching over 215MPa. The strength coefficient of the heat-affected zone after welding reaches over 80% of its room temperature value, making it more suitable for use in ice-melting device projects, large-capacity substation projects, renovation projects for old substations, and places with high temperature requirements.
