Description
Technical Field
The utility model relates to a cable, concretely relates to protection against rodents ant resistant ultraviolet control cable.
Background
Termites prefer to nest at the entrance and the periphery of the cable, and eat the outer plastic sheath of the cable to cause electric leakage, short circuit and communication interruption, even explosion and fire. Accordingly, termites are called "toothless tigers". With the rapid development of electric power and communication industries, the use amount of cables and optical cables is increasing day by day, and direct-buried cables are the most economical laying mode, so the opportunities of the cables suffering from the damage of termites and mice are correspondingly increased, and the problems of rat prevention and termite prevention of the cables are becoming severe day by day.
The problem that the outer sheath of the common control cable is damaged by organisms is increasingly prominent, and particularly the problems of rat prevention and termite prevention of the cable in southern areas need to be paid high attention. Mice and termites can bite through the cable sheath to damp the cable insulation and reduce the insulation resistance, thereby causing single-phase grounding short circuit and even causing explosion to cause permanent fault of the cable line. In addition, the common rat and termite prevention cable is not favorable for large-scale production due to insufficient environmental protection or high production cost.
