Product Feature And Application
The three phase pad mounted transformer is an oil filled distribution transformer designed for underground distribution loads in commercial settings like shopping centers, schools, and industrial plants. It comes in live front and dead front constructions, suitable for loop feed and radial feed applications, with or without taps. Featuring aluminum or copper windings, it's engineered for efficiency and compactness. Benefits include high voltage, stable neutral point, low loss, small size, cost-effectiveness, safety, environmental friendliness, and an appealing design.



Core features
Compartmental available in live-front or dead-front design
Critical load designed with special attention to surge protection
Hardened data center designed with special attention to surge protection, providing superior performance under the most stressful electrical environments
Solar specifically designed for Solar Photovoltaic generator step-up (GSU) applications
Vacuum fault interrupter combines both voltage transformation and either transformer or loop overcurrent protection in one space-saving, money-saving package
Can be located near or inside buildings for greater flexibility and savings
