Description
Technical field
The present invention relates to cable field, more particularly to a kind of novel and multifunctional cable
Background technology
Cable includes local telephone network cable, TV cable, light cable etc.；Mouse is rodent, and tooth grows all the life, daily
Its physiological habit must be kept with the tooth for the object abrasion fast-growth that bites, and the distinctive smell of plastics makes plastics turn into mouse
Class length bites object, posts the dark corner for staying in subterranean stream building mouse more, cable tunnel, groove, cable vertical shaft etc. all into
For the best place that mouse perches, therefore these cables are often bitten by mouse, and damaged by rats is the current main harm to cable
One of, the cable destruction mainly outer protective sleeve that damaged by rats is caused, which will be worn, causes cable to intake, and causes the feelings such as power failure, communicating interrupt
Condition, damaged by rats destruction excludes difficulty, also brings difficulty to maintenance work, and the tensile strength of the current cable of some is inadequate, fire resisting
Poor performance, causes the cable life-span not long.
The content of the invention
The present invention overcomes above-mentioned technical deficiency there is provided a kind of fire prevention, tensile strength is big, prevent the novel and multifunctional of damaged by rats
Cable
The present invention specifically uses following technical scheme to achieve these goals：
A kind of novel and multifunctional cable, including 5 circumferentially uniform cores, the cross section of core is sector, often
Bar core includes conductor and the insulating barrier being wrapped in outside conductor, and the material of insulating barrier is IXPE, 5 cable cores
Lapping layer, inner sheath, screen layer, armor, fireprotection layer, water blocking layer, capsicum element coating and oversheath, institute are enclosed with outside line successively
The fireprotection layer stated is the fire-resisting ceramic silicone rubber that thickness is 2~4mm.
Further, reinforcement cable core is provided with the lapping layer, it is aramid fiber complex fiber material to strengthen cable core material.
Further, screen layer includes being coated with the aluminium foil that thickness is 12um on the copper foil layer that thickness is 1.05um, copper foil layer
Layer, is provided through the through hole of copper foil layer and aluminium foil layer on screen layer, the through hole into array distribution, pitch of holes is 180-
620um, through-hole diameter is 120-330um.
Further, the material of described inner sheath is low-smoke halogen-free polyolefin, and oversheath is that thickness is 4~6mm PLC
Or PUR materials.
Further, the water blocking layer keeps off tide including dry filling oxidant layer, expansion waterproofing rope layer, radial direction from inside to outside
Layer, the basic unit for expanding the line that blocks water including woven dacron and the particulate expandable being bonded in basic unit, the material of particulate expandable is fibre
Dimension element.
Further, armouring restrictive coating is that the galvanized steel strip that thickness is 1.3~3.4mm is entwined, on galvanized steel strip
The even radiating aperture for being provided with a diameter of 310-520um.
Beneficial effects of the present invention are as follows：
1st, the present invention is simple in construction, and capsaicine figure layer can be bitten after oversheath when mouse son gnaws through, and capsaicine is produced to mouse
Raw strong impulse, drives mouse to abandon biting, even if capsaicine figure layer will be worn, and the inside armor prevents mouse from further gnawing
Cable is stung, so as to protect cable by damaged by rats；Fireprotection layer is the fire-resisting ceramic silicone rubber that thickness is 2~4mm, Ceramic silicon rubber
Under 500 to 700 degree flames, hard Ceramic flower protective layer is formed, isolation burning things which may cause a fire disaster fireproofing function is played, but at normal temperatures
The characteristic of silicon rubber is remained in that, the fire resisting effectiveness energy of cable is added.
2nd, it is aramid fiber complex fiber material to strengthen cable core material, and the tensile strength of this material is good, and cable adds armour
Dress layer can also be improved in addition to the mechanical protections such as enhancing tensile strength, compression strength increase the service life by shielding protection
Cable interference free performance.
3rd, water blocking layer includes dry filling oxidant layer from inside to outside, expansion waterproofing rope layer, radial direction moisture-proof layer, and the expansion hinders
The particulate expandable that waterline includes the basic unit of woven dacron and is bonded in basic unit, the material of particulate expandable is cellulose, block-water effect
It is good.
