Application
Product is the same with place which electro-area, such asliving area, emporia, industy, site of build, oil field,roadway, port airport and temporary electro-area of build and so on.
•Small bulk, perfect figuration. Convenience to fix, operate, upkeep, and credibilityto run.
•Three-phase five-column structure transformer winding connection group using Dyn11 connection with low loss, low noise, zero-sequence voltage from suppression, interfering phase voltage, lightning protection performance, the characteristics of unbalanced load capacity.
•We adopt back-up protective fuse and inserted fuse to protect it.
•Made crust of armor plate, and deal with especially technics to antisepsis.
•Crust protection grade is IP33.
