Manufacture of 8KA.211.386 Central Conductor by Casting Instead of Forging
8KA.211.386 central conductor is are one of key parts in SF6 high voltage apparatus.386 conductors were made from by LD2 forging Al alloy with forging process according.But the forging process for 386 conductor possesses many shortcomings such as long manufacturing period,high production cost,and low product quality.Through analysis and experiment the 386 conductors with cheap cost,excellent properties and satisfactory quality are successfully manufactured by self-developed ZDL2 casting Al-Si alloy and low-pressure casting process.Consequently,sets of SF6 high voltage apparatus have been completed on schedule and delivered on time.
