Single Phase Oil Immersed Distribution Transformer

Single Phase Oil Immersed Distribution Transformer

The oil immersed transformer has long service life and maintenance-free operation. The fully sealed transformer box cover and box edge are bolted or welded to isolate the contact between oil and air, and the insulation will not be damp, which greatly reduces the insulation aging speed and improves the service life.

The single-phase oil immersed distribution transformers are specifically designed for the decentralization distribution network of servicing residential overhead distribution loads of town and countryside. They are also suitable for light and diversified power applications. These transformers are designed for the application conditions normally encountered on electric utility power distribution systems.Offers 2 basic transformer types and 2 kinds of metal core types Conventional type and Complete Self Protect type,and for the transformer core, 2 types of materials are available: C.R.G.O. wound core and amorphous metal core.

Three phase oil immersed transformer 

oil immersed distribution transformer features
  • The Core is Made of High-Permeable Grain-Orientated Top Quality Cold-Rolled Silicon Sheet and The Material is Cut With Advanced Germany Automatic Shear Line with The Cut Burs Controlled Within 0.02mm; High Performance and Reduces Noises
  • The High-Voltage (Hv) Coil Adopts An Interleaved-Continuous Structure to Improve The Voltage Characteristics Under Impact Voltage,in The Transformer Winding There is A Zigzag Oil Guide Structure
  • The Tank Wall Adopts Wide Steel Sheet, Which Will Be Folded Into Corrugated Structure Without Splicing, in This Way Welds are Decreased And Mechanical Strength is Enhanced, Meanwhile, The Corrugated Wall Has Diverging Effect, And Thus Plays A Role in Decrease Of Noise
single phase oil immersed distribution transformer Advantages

a. High reliability, advanced performance, and reasonable economic indicators.

b. The magnetic core connector is a three-step ladder, and the surface of the magnetic core is coated with a curing coating to reduce loss and noise.

c. The winding structure is novel and the oil circuit design is reasonable. Its newly designed insulation structure helps to enhance its mechanical strength and short-circuit resistance.

d. There are various types of fuel tanks and they all look good.
