Claims

[Scope of Claim for Utility Model Registration] 1. Conductive wires configured such that a single coiled thin wire is embedded in the covering of the conductive wires over the entire length, and a weak current is supplied to the current detection means through the thin wire. damage detection structure. 2 In the covering of the conductor wires, a good electrical conductor is densely arranged in the inner layer over the entire length, and a coiled single thin wire is arranged in the outer layer, and a current detection means is connected to the former good conductor. The latter thin wire has a damage detection structure for conducting wires configured to supply a weak current to other current detection means through the thin wire. 3. The structure for detecting damage to conducting wires according to claim 1 or 2, wherein lamps are used as the current detecting means.
