As one of the key equipment (material) in power transmission and transformation system, corrosion-resistant 3A21 aluminum alloy tube bus plays an important role in the safe and reliable operation of power transmission and transformation system and power equipment.
Corrosion-resistant 3A21 aluminum alloy tube bus r conductor is generally installed on the overhead after welding (aluminum and aluminum alloy tube welding method is similar), and the overhead tube busbar conductor is fixed with special metal fittings .Due to the reduced strength of the joints after welding (national standard requires 62% of the wood), in order to avoid the bending of the joints after the overhead, the internal application of liner reinforcement of the joints, the welding between the two pillars should not be more than two.
