Description
Technical Field
The utility model belongs to a cable especially relates to a protection against rodents ant early warning power cable.
Background
With the rapid development of urban construction, electric power, metallurgy, petrochemical industry, industrial and mining enterprises, municipal administration and the like in China, the demand of various power cables matched with the power cables is increasing. Meanwhile, the south is rainy and humid, harmful organisms such as mice, termites and the like bring great hidden danger to the safe operation of electric facilities such as electric wires and cables, and different operation environments require that the electric power cables have the characteristics of rat prevention, termite prevention, moisture prevention, water prevention and the like, so that the electric power cables are required to have the characteristics of rat/termite bite prevention, moisture prevention, water prevention and the like in addition to good electric performance in order to provide safe and reliable electric power guarantee for electric equipment and circuits.
The existing power cable with the rat and ant prevention performance in the market is a cable capable of preventing rats and ants from biting. In order to prevent the rat and ant prevention cable from being bitten by rats and ants, a rat and ant material sheath is arranged on the outermost side of the rat and ant prevention cable. However, the pesticide effect of the protective sleeve made of the rat-ant material is gradually reduced when the protective sleeve is used for a long time, and especially in an environment with higher humidity, the pesticide effect of the rat-ant material is easy to lose or even disappear, so that rats and ants bite the protective sleeve, and electric accidents such as cable water inlet short circuit, breakdown and burning are easy to happen in a humid and water accumulation environment.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough of prior art, provide a protection against rodents ant early warning power cable.
This practical technical scheme who adopts of solving its technical problem is: the utility model provides a protection against rodents ant early warning power cable, includes the cable core, the cable core is established in polyethylene inner sheath, and polyethylene inner sheath outsourcing is equipped with two steel tape armor, is equipped with signal fiber outside the two steel tape armor, and signal fiber outsourcing is equipped with protection against rodents ant oversheath, the cable core include four conductors, the outside of conductor all wraps and is equipped with the crosslinked polyethylene insulating layer. The utility model discloses a polyethylene inner sheath, two steel band armor and protection against rodents ant oversheath are as the protection skin of protection against rodents ant in proper order, and protection against rodents ant is effectual, still has dampproofing function, is applicable to and uses under the higher place of protection against rodents ant requirement and environment. The signal optical fibers are symmetrically arranged in the rat and ant prevention outer sheath, so that the cable is bitten by rats and ants seriously, after the rat and ant prevention outer sheath is damaged, the signal optical fibers are damaged, an alarm is given when a transmission signal is interrupted, the damaged position of the cable can be checked in time, and the rat and ant prevention and control work is carried out.
