The multistage step lapped core shall be cut with a 45°joint seam, and pore-free binding construction, which reduces the noise as well as power consumption.
All windings are wound on an insulating cylinder of high strength. A special wire tensioner is adopted as well as the climbing pads under the wire transposition improve mechanical strength and short circuit resisting capability considerably.
Assembling and winding of power and distribution transformer are both finished in fully enclosed cleaning shop. This procedure meets the requirements on cleanness and constant temperature of core and winding assembly for the manufacturing of 500kV products, further ensuring the cleanness and dryness of the core and winding assembly. Kerosene gas-state drying device is used as well for optimizing cleaning of electrical distribution transformer.
Oil tank is in bell-shaped construction. The sealing parts of the oil tank is subject to special treatment the tank body has experienced shot-peened that thoroughly eliminates oxide skin on the surface and sharp angles, burrs, and weld slag created by processing.
