Isolation transformer is used for low-voltage distribution system, isolate load from power, reject stray common mode and dc voltages, ground loop potentials, electromagnetic interference (emi) and radio frequency interference (rfi) from Dielectric strength: l-l, l-g 4000vac/50hz/60s. Free of arcing breakage I se is less than 65db (to be measured at the point 1 meter away from the reactor horizontally) . Protection class: ip00 or as customer required. Insulation class: h Environment exists without gas, steam, chemical deposition, dust or dirt that will affect transformer¡¡¥s insulation seriously, explosive or corrosive medium is not allowed. Standard: iec726:1982 dry power transformer , gb6450-86(equivalent to iec726:1982) Standard carton or wooden case to the custom made transformer
