Product Description

 

Three-Phase Pad-Mounted Transformer Features
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, ANSI C.57.DOE, and IEEE) as applicable.
A wide range of features and accessories is available to satisfy almost any special requirement, including fuses, surge arresters, gauges, controls, cooling fans, pressure relief devices, load-break switches, and high-voltage tap switches. In addition to the standard mineral oil, alternate insulation fluids, such as silicone and seed-based vegetable oil are available for special applications.
