Description

A kind of termite-resistant rodent-resistant flame-proof environmental protection power cable

Technical field

The utility model relates to the power cable field, and particularly a kind of have a termite-resistant rodent-resistant flame-proof environmental protection power cable.

Background technology

At present, the electric wire and cable jacket material in actual use, except being subject to heat, oxygen, light, outside the destruction of the environment such as chemical erosion and mechanical stress, also can be subject to termite, the food erosion injury that mouse etc. are biological, and the common used PE of electric wire, the material such as PVC and low-smoke non-halogen flame-retardant, itself is to termite, the corrosion stability of the biology such as mouse is poor, so do not possess the ant-proof mouse-proof function, when cable laying in mouse, the area that termite is more or be laid in for a long time when underground, electric wire is easily by mouse and termite food evil, can cause the accidents such as power failure and communication disruption when serious, even because electric wire, cable is eaten to be produced short circuit accident after the evil and causes and people's social life and the development of the national economy etc. are had a strong impact on the harm such as fire.

At present the method for preventing and treating of mouse and termite is mainly contained two kinds of Physical and chemical methods:

1, Physical

Physical is the hardness of utilizing material, toughness and surface flatness reach prevention effect, such as ZL200720143825.4, ZL201020694214.0, ZL201020694151.9, ZL201020694153.8, ZL201020694154.2, the described method such as ZL201020694176.9 all is to adopt sheath to set up the termite-resistant rodent-resistant layer that nonmagnetic material is made outward, this layer material itself is pollution-free, not corrosion, and can prevent mouse ant destruction, also has the HMW high density polyolefins sheath described in the ZL200710131185.X etc., although do like this environmental protection, the termite-resistant rodent-resistant effect is remarkable, in the practical application, because it is larger that material is extruded difficulty, and expensive, production cost is higher, so seldom use.

2, chemical method

Chemical method is to add a certain amount of repellant or repellent in material, such as the dieldrite of anti-ant, drinox, lindane, Niran, heptachlor, chlopyrifos etc., the terpenoid compound monomer such as the cycloheximide of repellent mouse, bioMet-12, R-55, three phenarsazine halide, triazine organo-tin compound, organic nitrogen phenyl formamidine and Gao Bingti etc.Such as ZL02212768.2, ZL200810028373.4, dissimilar repellant such as the usefulness described in the ZL200910265813.2 etc. comes termite-resistant rodent-resistant.But many repellants not only have toxicity, and along with the prolongation of time, can make mouse and termite that smell etc. is produced paralysis, produce in the course of time antibody, the population that olfactory nerves is not driven Odor stimulation in a kind of body that finally can make a variation out in its colony.So after a while, the type technology of driveing can only be driven most of has the biology of harm to cable, and can not drive the biology of small part variation, the effect of control worse and worse, electric wire also will slowly be compromised.Simultaneously there is the harmfulness of contaminated environment in this type of medicine, and is larger to the human influence, some in addition belong to carcinogen, therefore effect is also not ideal in actual the use.

So, no matter be a lot of deficiency that adopts physical method or chemical method all to exist.

The utility model content

The technical problems to be solved in the utility model provides the cable that a kind of energy rat-and-ant proof bites, flame-proof environmental protection is good, technique is simple, cost is low.

A kind of termite-resistant rodent-resistant flame-proof environmental protection power cable described in the utility model comprises cable core, and the gap in cable core is provided with filling, extrudes inner sheath outside cable core, and outermost layer extrudes oversheath; Described cable core is to form by several insulated wire cores are stranded.

Described insulated wire cores is by conductor and is coated on successively conductor outer conductor shield, insulating barrier, insulation screen and combines.

The beneficial effects of the utility model are:

Active additive and environmental-protection flame-retardant material that the juice that extracts from some special plant by adding in insulation of the present utility model and the sheath material is made; multiple protective has also fundamentally solved the bite behavior of cable of mouse ant; and usefulness is the environmental protection flame retardant CABLE MATERIALS; therefore very environmental protection;, also can not damage people and other animal without harm soil, water quality and air etc., and owing to directly do not kill the mouse ant; ecological to conservation of nature, keeping biological chain etc. has positive effect.Owing to mainly be to consider from the material of making cable, production technology and technique are identical with general cable production, so technique is simple, and easy and simple to handle, practicality and economic benefit are all very high.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Embodiment:

As shown in Figure 1, a kind of termite-resistant rodent-resistant flame-proof environmental protection power cable described in the utility model comprises cable core, and the gap in cable core is provided with fills 7, extrudes inner sheath 5 outside cable core, and outermost layer extrudes oversheath 6; Described cable core is to form by several insulated wire cores are stranded; Described insulated wire cores is by conductor 1 and is coated on successively conductor 1 outer conductor shield 2, insulating barrier 3, insulation screen 4 and combines.

The method that the utility model adopts, make the active additive of mixing from some special extracted form natural plant leafing juice, root juice and bar juice first, the concertedness, intermiscibility and the animal migration that recycle various juice make the mixed active additive give play to maximum effectiveness, this type of active additive is added to make the termite-resistant rodent-resistant cable in the environmental protection flame retardant CABLE MATERIALS at last.

Principle of the present utility model: a class plant of extracting juice is that the juice of smell own or root, leaf, bar can have repellent action to the mouse ant, around reaching, the place of its growth do not have the existence of mouse ant, like this in case the active additive of being made by its root, leaf or bar add to make cable in the CABLE MATERIALS after, mouse or termite dare not near cable, make cable avoid the destruction of mouse ant.Another kind of plant is its root, the juice of leaf or bar has can benumb or corrode neural effect, when cable since a period of time or some special circumstances so that after the function of its lost repellent mouse ant, the mouse ant is at the cable that bites, the activating agent that extraction juice is made penetrates in the root of the tooth nerve of mouse ant, make its root of the tooth neural paralysis even corrosion, the interlock dynamics reduces, no longer destroy cable, and it is constantly ground one's teeth in sleep, cause loss of tooth or interlock difficulty, fundamentally solve its behavior of destruction cable that bites, even make the mouse ant of other cable that do not bite produce the feared state of mind, can not remove the cable that bites.

The utility model provides a kind of termite-resistant rodent-resistant flame-proof environmental protection power cable structure form and implementation method; the above only is preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
