Abstract

A theftproof cable, comprising a twisted conductor bundle and a sheath wrapping the twisted conductor bundle, is characterized in that hard metal rods are arranged in linear sequence and connected at both ends in the core area of the twisted conductor bundle. In the utility model, high hardness of the metal rods in the core of the cable can stand the cutting of a long iron cutter, a hand saw, an axe and so on, therefore thieves can not cut off the whole cable easily in one trial and they have to try another direction to cut the other part. However, whether cutting the cables of high altitude or underground, the operation is rather hard because the direction is unfavorable. Besides, the relatively high hardness of the metal rods will break the cutting edge, thus spoiling the tools, prolonging the theft time and enabling the policeman and patrolmen arrive timely. The utility model has the advantages of simple structure, low cost, effective theftproof function, applicability in making theftproof power cables and theftproof communication cables, and wide application prospect.
