1. A compensation block for an air-core reactor or a transformer, the compensation block comprising:
a sandwich structure with an upper insulating material block, a lower insulating material block, and an elastomer block disposed between said upper and lower insulating material blocks;
the compensation block having a slot formed therein for connecting an upper spider arm of the air-core reactor and said compensation block together in a form-fit having a meshed connection;
said upper spider arm having a rectangular cutout formed therein, with said rectangular cutout having a width corresponding to a width of said compensation block and a height corresponding to a part of a height of said upper insulating material block of said compensation block, wherein said compensation block is arrangeable between a winding end and said upper spider arm of said air-core reactor, and wherein said slot is formed to receive the portion of said spider arm above said rectangular cutout.
