The power cable is a cable for transmitting and distributing power, and with the wide application of automation technology, various electrical facilities are increased, the capacity of the power cable is increased, and the possibility of fire is increased. Traditional low pressure 0.6/1kV power cable is owing to adopt the polyvinyl chloride sheath, and polyvinyl chloride is easy fracture under the low temperature condition, and when the conflagration took place, it is fast to stretch, and the smoke concentration is high, causes the potential safety hazard easily, and waterproof performance and temperature toleration are also poor. With the development of urban construction, the cable and optical cable lines have the development trend of being erected from high altitude to buried underground, and are more easily damaged by eating and eroding by organisms such as termites, mice and the like. The PE and PVC flame-retardant materials adopted by the cables and the optical cables are poor in corrosion resistance to organisms such as termites and mice, the cables and the optical cables which are made of the materials as the outer sheaths do not have the functions of preventing the termites and the mice, when the PE and PVC flame-retardant materials are laid in areas with more rats and the termites, the cables and the optical cables are eaten by the rats and the termites, and accidents such as power failure and communication interruption can be caused in serious cases.
In most industrial areas and industrial parks, low voltage power cable all lays along same circuit with the optical cable, often appears laying the condition that the optical cable was laid in the repeated excavation again behind the cable, and manpower and materials have been wasted in the repeated laying. A combination cable which can effectively reduce potential safety hazards, is convenient and quick to construct and reduces construction cost is urgently needed.
