Description
Technical field
The present invention relates to field of cables, specifically a kind of crosslinked polyetylene insulated protection against rodents power cable.
Background technique
Electric wire and cable jacket material is in use in addition to by oxygen, heat, light, power, outside the destruction of the environment such as chemical erosion,
Also suffer from the biology such as termite, mouse or hare food erosion injury, so as to cause power outage, telecommunication interruption, computer wiring
It is happened occasionally by phenomena such as generation movement stopping after mouse food evil and maloperation, evil is eaten by mouse due to electric wire, cable and generates short circuit
Accident and the harm such as cause fire, make social activities and national economy by heavy losses.
Termite has bite habit during looking for food, and electric wire, cable sheath material will appear " duck eye after being destroyed by bite
Cave " and cause electric wire, cable fault, when electric wire that these are encroached on, cable dampness or when entering water, cause leak electricity short-circuit, even
The accidents such as explosion are caused, as Preventing Countermeasures：Physical method is useful by the protective metal shell formed using corrugated metalpipe and thin steel strip
Plastics or glass reinforced plastic pipe carry out physical protection to cable core, and novel high-strength charcoal element pipe, which starts to obtain, in recent years uses chemistry
Method is that a certain amount of repellant or repellent are added in cable lining material, has repellent or poisoning to make biology to play
With.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of crosslinked polyetylene insulated protection against rodents power cable.
A kind of crosslinked polyetylene insulated protection against rodents power cable, including several mutually twisted cables core, the cable core

Several connection frames being equally spaced are provided on the nylon sheath wire, it is annular that cross section is provided on the connection frame
Ring stand.
The compound protection against rodents layer is that chromium-plated steel band is combined with highdensity polyethylene.
The groove of the capsaicine for placing protection against rodents is provided on the compound protection against rodents layer.
It is triangular shape and the point for impregnating onion precision that cross section is provided on the compound protection against rodents layer and nylon sheath wire
Angle.
The axial cord is the rope made of hemp.
It is set between the annealing copper conductor and crosslinked polyetylene insulated layer, between crosslinked polyetylene insulated layer and polyester belt
It is equipped with the fiberglass layer for filling.
The beneficial effects of the invention are as follows：The wedge angle for impregnating onion precision is respectively provided on nylon sheath wire and compound protection against rodents layer,
It plays and drives mouse and mouse is not easy to sting bad effect, while cooperating ring stand to take convenient for user to prevent from pricking the hand；Compound anti-
Groove for placing the capsaicine of protection against rodents is set on mouse layer, deepens the effect for driving mouse；Physical method is simultaneous with chemical method
With raising rodent-proof characteristic.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is schematic view of the front view of the invention；
Fig. 2 is the I partial enlarged view of Fig. 1 of the invention；
Fig. 3 is overlooking structure diagram of the invention.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
As shown in Figure 1 to Figure 3, a kind of crosslinked polyetylene insulated protection against rodents power cable, including several mutually twisted cables
Core, the cable core include anneal copper conductor 1, be extruded in annealing copper conductor 1 outside crosslinked polyetylene insulated layer 2, it is described
Cable core twisted center at be provided with axial cord 12, the outside of the cable core is surrounded with polyester belt 6, the polyester
Outside with 6 is extruded with acrylonitrile butadiene flame-proof layer 5, and the outside of the acrylonitrile butadiene flame-proof layer 5 is extruded with metal armouring shielding
Layer 4, the outside of the metal armouring shielded layer 4 are extruded with the compound protection against rodents layer 7 for impregnating protection against rodents liquid medicine, and described is compound anti-
