Product Description
Well-Constructed 600kVA Isolation Transformer 400V/ 220V

Adopted high quality materials and advanced techniques, by oil-cooled method, via vacuum pressure impregnating and strict quality-inspection, SO oil-cooled LV transformers possess following features:High efficiency, low loss, low noise, high reliability and strong load capacity;
SO air-cooled LV transformers are classified into:Auto transformer, isolation transformer, single phase transformer and three-phase transformer;
Input voltage:Three-phase 440V,420V,400V,380V,etc.
Output voltage:Three-phase 440V,380V,220V,200V,190V,120V,100V,etc.
Single phase and special products can be made as per requirements.

-- Small size, light weight, easy installation, maintenance-free, good economic performance.
-- Low noise, low loss, good thermal performance, strong overload capability.
-- Good moisture resistant ( run properly in 95% relative humidity environment)
-- Small capacity of partial discharge, good insulation properties
-- High mechanical strength and good thermal stability
-- Good flame retardant capability, with automatic flameout characteristic, can be installed in the load center.
1. Air-cooled method and vacuum pressure impregnating technology with ensured quality;
2. 97% high efficiency with low loss,low loise, strong load capacity;
