ることが行われている。The main reason for this is thought to be the intrusion of moisture such as rainwater through the sheaths and ends of the wires. For this reason, in order to prevent the intrusion of moisture and the like, a watertight compound is coated and filled between the conductor strands and the outer periphery over the entire length of the electric wire.
