The power series of EGE busducts can handle up to 25 kA for self-cooled IPBs and 50 kA for forced cooled IPBs as follows:Isolated phase busducts (IPB) with air insulationThis type of duct is used primarily for the outlet of generator outputs at current levels as high as 28kA and voltages of 36kV. The basic principle of the busducts' arrangement enables magnetic field radiation to be reduced to below 5%, as well as contributing to simplified handling and minimising potential interruptions for maintenance.Isolated phase busducts (IPB) with forced coolingThis type of busduct is used for the outlet of generator outputs at current levels of up to 40kA and voltages of 36kV. Cooling can be in the form of air sucked directly in from the environment surrounding a generator or via a cooling unit. The basic principle of the busducts' arrangement enables magnetic field radiation to be reduced to below 5%. Moreover, their simplicity is unique when it comes to replacing insulators or fixing them onto steel structures.Isolated phase busducts (IPB) of internal consumptionBusducts such as these are primarily used for transmitting outputs between a unit auxiliary transformer and a switching station. They prove both maintenance free and space saving due to their exceptional design, which features a single insulator. In some cases, they can even be used for the outlet of generator outputs at short circuit ratios rated up to Ipeak=125kA and Ith=50kA/1s.
