Our pad mounted transformer is designde and tested in accordance with industry standards including CSA,ANSI C.57,DOE,and IEEE as applicable.
Pad Transformers are made in power ratings from around 500 to around 10000 kVA and often include built-in fuses and switches.
The Liquid-Filled Loop Feed Pad Mounted Transformer is an oil-filledthree-phase, commercial pad mounted distribution transformer specifically designed for servicing such underground distribution loads as shopping centers, schools, institutions and industrial plants. lt is available in both live front and dead front construction, for loop feed applications. with or without taps. The transformer uses aluminum or copper winding and is optimized to maximize efficiency and footprint. lt has many advantages: such as high voltage, no drifting of neutral point, low loss small volume, cost-effective, safety and environment protection. attractive appearance and etc.
Our Liquid-Filled Loop Feed Pad Mounted Transformer is designed andtested in accordance with industry standards (including CSA, ANSIC.57.DOE, and IEEE) as applicable.
Pad Mounted Distribution Transformers Winding
The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.
