Summary
The three-phase oil-immersed distribution transformer applies new type insulating structure and makes short-circuit resistance strong. The iron core is made of high-quality cold-rolled silicon-steel plate. High voltage winding group is made up of high quality oxygenfree copper lines and it adopts multilayered
drum type structure. All fasteners have been processed with special treatment to prevent them from loosening
Reliable Structure
Spiral loops with longitudinal oil path to produce a better interior cooling effect; Improve the effectual support of the loop’s terminal face to strengthen the anti-short circuit electricity capability; New suspending structure and instrument-positioning frames to guarantee that the long distance transport and movement will be more reliable.
Excellent Materials
Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short
circuit.Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.High quality rubber sealing material, which can prevent the transformers form aging or
leakage.

|
Have good ability withstand short-circuit
|
|
5
|
The oil tank is bell type with the structure of full folding plate type,
|
|
6
|
Having an excellent exterior and easy for maintenance
|
|
7
|
Adopting capsule-type oil container, it can reduce oil aging to the lowest degree

Core
|
1
|
Power transformer core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet
|
|
2
|
The material is cut with advanced Germany Geoge GmbH automatic shear line with the cut burrs controlled within 0.02mm.
|
|
3
|
Power transformer silicon sheet fabrication adopts “no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45 full-miters
|
|
4
|
Effectively improves no-load performance and reduces noises.
|
|
Coil
|
1
|
The high-voltage(HV) coil adopts an interleaved-continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed.
|
|
2
|
All stays and pads are chamfered to keep highly reliable insulation.
|
|
Oil tank and accessories
|
1
|
Power transformer tank wall adopts wide steel sheet
|
|
2
|
Which will be folded into corrugated structure without splicing
|
|
3
|
In this way welds aredecreased and mechanical strength is enhanced
|
|
4
|
The corrugated wall has diverging effect, and thus plays arole in decrease of noise.
