Its depending on cable dimension, current carring capacity and soil thermal resistivity.
EHV - EXTRA HIGH VOLTAGE - STARTING 500 KILOVOLTS IN UP (500,000 VOLTS)
EHV lines are type of electrical lines commonly used for experimentation in physics. They stand for 'Extra High Voltage' lines.
EHV = Extra High Voltage. To quote from the Wikipedia article (see link) "...this refers to equipment designed for more than 345,000 volts between conductors." Put simply - EHV transmission is the 'national grid' power system.

Cross bonding of Extra High Voltage (EHV) underground cables involves connecting the metallic sheaths of each cable together at regular intervals in order to mitigate the effects of induced voltages and currents during faults or transient conditions. This helps in reducing the risk of insulation failures and ensures the overall safety and operational reliability of the underground cable system. Proper design and installation of cross bonding are essential to maintain a low-resistance path for fault currents to flow through, thereby preventing damage to the cables and associated equipment.
