Description
With natural cooling the rated current reaches 28 kA, and with forced cooling up to 40 kA. Short-circuit withstand of the auxiliary-service busducts is up to Ipeak 125 kA and Ith 50 kA/1 s. The insulation is air, and each phase sits in its own enclosure, so the external magnetic field is reduced to less than 5 %. The busducts are built to IEC and ANSI standards.
