The attenuation caused by the capacity between the cable wires can be reduced by induction coils (Pupin coils). The "Pupin pot" is an underground container that serves for placement of the Pupin coils. The Pupin pot was buried in earth without any special protection. The cable passes the bond space of the pot, therefore it is transit cable type. In the long-distance cable, a pot in each 1,830 section had to be installed. The major parts of coils and pot: Annular iron core, red copper coil coiled on it, internal copper container, and external cast iron casing.
