<p>The present invention relates to an electric wire which is generally used. The electric wire which is usually used becomes the reason of a large accident due to the inflow of water by damage to an insulation sheath. For solving this problem, the present invention is disclosed. The insulation sheath (2) is coated on the outer sides of a plurality of conductors (1) with an elliptical shape. A reactor (3) whose color is changed by reacting to liquid is coated on the outer sides of the insulation sheaths (2) with the elliptical shape. An insulation sheath (4) to observe the reactor is coated on the outer side of the reactor (3) with the elliptical shape. Thereby, damage is previously sensed before the insulation sheath (2) is damaged after the insulation sheath (4) is damaged. Thereby, an electric shock accident due to the damage to the coating of the electric wire is reduced. The damaged point of the coating of the electric wire is easily found if a circuit breaker is operated before and after an operation.</p> |
