Electric underground line system

摘要

The line system has at least one parallel compensation line spaced relative to the line system, for providing current flux magnetic field which reduces the magnetic field of the line system. The compensation line lies in thermic contact with the cooling medium of a lateral cooling system. Pref. the compensation line is provided by at least one conductor wire associated with the cooling medium flow channel, e.g. wound around the outside of the cooling medium flow channel.
