Abstract
The invention relates to a highly-filled rat-proof termite-proof compressive data cable, which comprises a cable core and a protective cover wrapped outside the cable core; the protective cover comprises an outer polyolefin protective cover and an inner polyethylene protective cover; a steel belt and an armour layer are sequentially arranged between the outer polyolefin protective cover and the inner polyethylene protective cover from outside to inside; the cable core is a conductor formed by winding a plurality of electrical units together; each electrical unit comprises a metal bare wire and an ethylene propylene rubber insulating layer wrapped outside the metal bare wire; soft polyurethane foam plastic is filled among the electrical units; and a fireproof insulating reinforcing part is wrapped in the soft polyurethane foam plastic. The highly-filled rat-proof termite-proof compressive data cable disclosed by the invention has better rat-proof and termite-proof properties and pressure resistance, and is capable of protecting integrity and safety of inner structures and reducing damage to the environment.
Description
Technical field
The invention belongs to power cable technical field, be specifically related to a kind of high filling rat-and-ant proof resistance to compression data cable.
Background technology
The application of cable very wide; purposes also very large; there is the place being much applied in mouse and often haunting; due to the grinding tooth of mouse; often can bite the outer jacket of cable; cause the accidents such as short circuit, power failure, control misoperation, communication, signal interruption frequently to occur, cause great harm to society and personal property, cause the economic loss that cannot estimate.
In order to overcome damaged by rats phenomenon; the main periphery adopting the protection against rodents restrictive coating of drug containing to be coated on cable and wire at present; when restrictive coating is because of after the reasons such as transport, embedded underground construction are subject to mechanical damage, viral marketing bites along its breakage, does not have basic protective effect.
The primary structure of present cable is made up of cable core and sheath, core cross section is mostly circular, there is space by between the core that stranding is adjacent, because space can affect the compactness of the construction of cable, when using for a long time or be subject to extraneous extruding, cable can be made to deform.
General cable does not possess good fillibility, and in construction with when pulling, adjacent core continuous friction can destroy the overall structure type of cable core, and the normal work not only affecting cable also destroys the aesthetic property of entirety.
Therefore, the rat-and-ant proof how improving electric wire is baited and resistance to compression, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The invention provides a kind of high filling rat-and-ant proof resistance to compression data cable, there is good rat-and-ant proof and crushing resistance, and reduce the harm that environment is caused.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of high filling rat-and-ant proof resistance to compression data cable, comprise cable core and be coated on the protective jacket outside described cable core, described protective jacket comprises polyolefin oversheath and polyethylene inner sheath, is provided with steel band and armour successively from outside to inside between described polyolefin oversheath and polyethylene inner sheath.Adopt duplex sheath structure; oversheath is polyolefin jacket; inner sheath is pe sheath; armour and galvanized steel strip is provided with between inner sheath and oversheath; effectively can stop biological the baiting and destroy such as mouse ant; protect the complete of internal structure and safety, can crushing resistance be improved simultaneously, ensure that inner cable core normally works.
Preferably, described cable core is the conductor that some electric units are intertwined, and described electric unit comprises metal bare wire and is coated on the ethylene propylene rubber insulated layer outside described metal bare wire.
Preferably, between described electric unit, be filled with flexible polyurethane foams, in described flexible polyurethane foams, be enclosed with fire-proof heat-insulating reinforcement.Have employed flexible polyurethane foams between cable core internal electrical unit to fill, form the soft right foam matter packed layer of plasticity, better can fill the space between cable core, inner structure is more compacted, even if be subject to extraneous extruding, cable also can remain unchanged shape, and flexible polyurethane foams to have water absorption high, the characteristic that water preventing ability is excellent.
Preferably, described fire-proof heat-insulating reinforcement is glass fibre belt.Glass fiber tape adopts high-temperature-resistant high type glass fibre, processes through special process.There is high temperature resistant, insulation, insulation, fire protection flame retarding, corrosion-resistant, ageing-resistant, the feature such as weatherability, high strength, smooth in appearance.Spun-glass insulation heat insulating belt, silicon rubber glass fibre is mainly divided into protect heat insulating belt, glass radiation proof heat-preserving heat-insulating belt etc.
Preferably, be provided with water blocking layer between described polyethylene inner sheath and cable core, the fill gaps between described water blocking layer and cable core has water-blocking material.Water blocking layer is waterstop, water blocking yarn or PUR, and water-blocking material is ointment.
Preferably, described steel band is galvanized steel strip.Galvanized steel strip has the effect of certain mask voltage.
Preferably, described armour is phosphating steel wire.
The invention discloses a kind of high filling rat-and-ant proof resistance to compression data cable, adopt duplex sheath structure, oversheath is polyolefin jacket, inner sheath is pe sheath, be provided with armour and galvanized steel strip between inner sheath and oversheath, effectively can stop biological the baiting and destroy such as mouse ant, protect the complete of internal structure and safety, can crushing resistance be improved simultaneously, ensure that inner cable core normally works; Have employed flexible polyurethane foams between cable core internal electrical unit of the present invention to fill, form the soft right foam matter packed layer of plasticity, can more be compacted in the space of better filling between cable core by inner structure, even if be subject to extraneous extruding, cable also can remain unchanged shape, and flexible polyurethane foams to have water absorption high, the characteristic that water preventing ability is excellent.
