500-7500kVA Three-phase Pad-mounted Transformer
- Details
Three-phase pad-mounted transformers is oil-filled,three-phase,commercial pad mounteddistribution transformer specifically designed for outdoor installation on a concrete pad and provideunderground power distribution to commercial,industrial and institutional loads.It is availablein both livefront and dead front construction,for radial feed and loop feed applications,with or without taps,thetransformer uses aluminum or copper winding and is optimized to maximize efficiency and footprint.It hasmany advantages:such as high voltage,no drifting of neutral point,low loss,small volume,cost-effective,safety and environment protection and etc.
Standard Features
