80kV - Class Hight Capacity , Power Distribution Transformer , Three Phases , Two Winding
Due to different power grid system in local countries, most oversea transformers must be designed and calculated before final accurate quotation. With this team of professional engineers, Pearl Electric could give a quick and accurate quotation, thus to meet end-user's application requirements.
Since clients from many countries will have different kind of reasons during inquiry, our expenrienced engineer will try to designed according to the need. Thus please give product specifications as detailed as possible when you request , thus to ensure the product design actually fit your practical needs.
|By winding number||
80kV class 3-phase two-winding power transformer
80kV class on-load tap-changing power transformer
80kV class off-load tap-changing power transformer
Pearl Electric's technology enable no-load loss decreased averagely 10.3%, no-load current decreased 22.4%.
The three-phase power transformer adpots new type insulation structure enable the strong shot-circuit resistance.
· Long Service Life
Transformer tank adopts fully sealed structure, fuel tank and tank rim can be connected by bolts or welded firmly, the transformer oil doesn't contact with the air, extending the service life.
· High Reliability
Pearl Electric is using high qualitity sealing parts and NBR gaskets for the fuel tank , improves the reliability and enhance the technical level to ensure the reliability of the seal.
· Compact Structure
Transformer tank uses the pannel-type radiator fins. when the oil temperature changes, the fins board expands from the heat and contracts from the cold.
Oil-filling/impregnation under vacuum
When a transformer is designed to be oil-filled under vacuum, an instruction to this effect shall feature prominently on the rating-and-diagram plate or on a separate plate mounted adjacent to it.
All transformers installed in vacuum-proof tanks shall be oil impregnated and filled under vacuum.
Oil impregnation or drying under vacuum shall be done with the transformer and oil at a temperature of at least 60 °C.
The duration of the treatment shall be such that is results of the in moisture content is as specified in clause 4.10.3 Moisture content.
Procedures shall be submitted for approval and full instructions shall be included in the transformer manual.
See 4.17.9 for the detail requirements of the conservator systems.
4.10.7 Poly Chloride Biphenyls (PCB) content
All oils used in the transformer and its accessories shall be free of PCBs (zero ppm).
A formal test certificate to this effect shall be included in the transformer manual.
