Description

The existing power line mainly comprises an outer sheath, an inner sheath and conductors, and common transmission conductors comprise metal wires made of copper and aluminum materials. Because the main protection structure of the power line is made of rubber materials, the rubber materials for protecting the power line can be gradually melted and even burnt under the action of high temperature when a fire disaster happens, and therefore the metal conductor is exposed. If the conductor is not powered off at the moment, the conductor is likely to be mistakenly touched by fire fighting personnel, so that a greater safety accident is caused, and a great potential safety hazard is further realized.
