Product Description

Three Phase Electrical Pad Mounted Step Down Oil Immersed Transformer 1000kva 15kv





WINLEY offers a complete line of liquid-filled ThreePhase Pad-Mounted distribution transformers that meet applicable ANSI®/IEEE® standards.With high voltages up to 34.5 kV and ratings up to 5,000 kVA, It is suitable for high-voltage and large-capacity occasions, such as power substations, industrial power consumption, etc. In high-load, high-voltage scenarios, oil-immersed transformers have better performance and stability.


Three Phase Electrical Pad Mounted Step Down Oil Immersed Transformer 1000kva 15kv 0




1) The structure is compact and reasonable, and the volume is small, which is only about one-third of the European-style box change of the same capacity;
2) Fully sealed, fully insulated structure, no need to set up safety barriers, and reliable guarantee for personal safety;
3) There are a variety of power supply schemes for users to choose from, which can adopt terminal power supply and realize ring network or dual power supply;
4) S11 oil-immersed power transformer is adopted, which has low loss, low temperature rise and strong overload capacity;
5) Double fuses (backup protection fuse + plug-in fuse) are used for protection, and the plug-in fuse fuse has the current and temperature dual sensitivity characteristics to ensure the safe and reliable operation of the product;

Standard Features

Pad-mounted transformers are made in power ratings from around 75 to around 5000 kVA and often include built-in fuses and
switches. Primary power cables are connected with elbow connectors, which can be operated when energized using a hot stick and
allows for flexibility in repair and maintenance.
Our pad mounted transformer is designde and tested in accordance with industry standards including CSA,ANSI C.57,DOE,and IEEE as applicable.
