110KV/132KV/220KV oil immersed power transfomrer.
The 110KV/132KV/220KV oil immersed transformer of our company is independetly deisgned according to characteristics of the grid in urban and rural of China.Its performance indices are superior over GB/T6451 Specification "Three-phase oil immersed power transformers technical parameters and requirements".The products are featuring in low loss.low noise,free of active part lifting,It is innovative in terms of safety ,reliability .and economy.Features of the products are introduced as follows:
1.Energy conservation
Low losses.
2.Core
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.
3.Winding
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.
4.Insulation
Assembling and winding of transformer are both finished in fully enclosed cleaning shop. This procedure meets the requirements on clearnness and constant temperature of core and winding assembly for the manufacturing of 550KV products,further ensuring the cleaning of product.
5.Tank
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 ellinates oxide skin on the surface and sharp angles,burrs,and weld slag created by processing.
