Welding technology of special-shaped brass rod and flat aluminium wire in dry-type transformer is to drill holes at one end of brass rod and tap wires in holes, then heat the hole end to reddish with welding torch, fill the holes with three-and-one wire, pure aluminium wire and three-and-one wire in turn, then drop 3-5 water on the surface of holes, heat one end of flat aluminium wire and insert it into the holes, then use three-and welding wires to weld the holes. After the beam, the brass rod and flat aluminium wire welded can be cooled in water.

Special Brass Bar

Welding technology of special-shaped brass rod and flat aluminium wire in dry-type transformer is through drilling and tapping at the top of brass rod, expanding it after burning red, then filling the hole with three-way wire, pure aluminium wire and three-way wire in turn, and making these materials pile up the hole and slightly protrude out of the hole, then burning red flat aluminium wire and inserting it into the hole for welding, which not only saves a lot of three-way wire. Moreover, the weld seam is strong and beautiful, and there will be no explosion and crack, which greatly improves the product quality and service life.
