Oil Immersed Transformer 1000kva


ISO Pad Mounted Transformer


1MVA Oil Immersed Transformer

Product Description

Three phase 1000kva oil immersed electrical pad mounted types Transformer 34.5KV to 208V



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.


Product structure


1) The transformer part and the control cabinet part of the United States variation, of which the transformer part is a fully sealed structure, and the insulating oil can be two types of high ignition point oil or ordinary oil.
2) The control cabinet is divided into a high-voltage room and a low-voltage room.
3) The high-voltage room is equipped with: high-voltage cable plug, lightning arrester, load switch operating handle, non-excitation tap switch handle, plug-in fuse, pressure release valve, thermometer, pressure gauge, oil Position gauges, oil filling plugs, oil drain valves, etc., load switches, off-excitation tap changers, plug-in fuses, etc. are all immersed in transformer oil together with the transformer core. The high-voltage cable and the transformer are connected by elbow cable connectors.
4) The low-voltage side can be installed with air circuit breakers, current transformers, as well as electric energy meters, ammeters and voltmeters, and output circuits and capacitance compensation devices can be configured according to user needs.
