Abstract
The invention discloses a low-smoke and halogen-free waterproof compensation coaxial cable resistant to drag. The low-smoke and halogen-free waterproof compensation coaxial cable resistant to drag comprises a center conductor, a skinning layer, an outer conductor, an armoring layer and a low-smoke and halogen-free protection cover. A waterproof layer and a metal layer are sequentially wrapped between the armoring layer and the low-smoke and halogen-free protection cover. The waterproof layer is formed by connecting a non-water-absorption layer and a water absorption layer in a cross mode; the non-water-absorption layer is made of polyurethane with latex threads added, and the water absorption layer is composed of high-water-absorption wood pulp cellulose. The metal layer is formed by wrapping a nickel wire reinforced graphite wire with a steel wire in a weaving mode. The cable is good in electrical conductivity, resistant to acid and oil, low in smoke, free of halogen, environmentally friendly, wide in application range, high in drag resistance and good in waterproof performance, and is mainly applied to the fields of power generation, metallurgy, chemical oil and the like.
Description
Technical field
The invention belongs to field of cables, relate in particular to the anti-waterproof compensating coaxial cable that pulls of a kind of low smoke and zero halogen.
Background technology
At present, along with socioeconomic development, cable consumption increases rapidly, and the quality requirement of cable is also constantly improved.Existing cable is generally that surface cover has sheath outside cable, between cable and sheath, sealing ring is housed, and its waterproof effect is not good, tensile property is also poor, and easily cause environmental pollution, long-term use easily there is infiltration in cable or the problem such as cable breakdown, just may cause very big hidden danger.Only meet the requirements, could the better fail safe that ensures these field inner cables.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind ofly conduct electricity very well, low smoke and zero halogen environmental protection, anti-ly pull, the anti-waterproof compensating coaxial cable that pulls of low smoke and zero halogen of waterproof.
The present invention takes following technical scheme to realize: a kind of low smoke and zero halogen is anti-pulls waterproof compensating coaxial cable, and it comprises center conductor, skinning cortex, outer conductor, armour and low smoke and zero halogen protective sleeve.Between described armour and described low smoke and zero halogen protective sleeve, wrap up successively watertight composition, metal level; described watertight composition is made up of the crosslinked water accepting layer of non-water accepting layer; described non-water accepting layer material is the polyurethane that adds rubber latex thread; described water accepting layer is for being made up of high water absorption wood pulp fibres; described metallic sheath is to strengthen graphite line by nickel wire, and outsourcing braided steel wire forms.
Described center conductor by multiply nickel plating annealed steel coppered wire to the right stranded 270 ° form, described skinning cortex is the organic silicon ribbon that adds glass fibre, carbon powder particle, described outer conductor is fine copper.
The present invention has following beneficial effect in sum: this cable conduction performance is good, acid-resisting and oil-resisting, low smoke and zero halogen environmental protection, of many uses, mainly apply to the fields such as generating, metallurgy, chemical petroleum, anti-to pull performance high, simultaneously, water resistance is excellent, allows cable to be in for a long time in water environment.
Brief description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, center conductor; 2, skinning cortex; 3, outer conductor; 4, armour; 5, watertight composition; 6, metal level; 7, low smoke and zero halogen protective sleeve.
Embodiment
The object of this invention is to provide a kind ofly conduct electricity very well, low smoke and zero halogen environmental protection, anti-ly pull, the low smoke and zero halogen of acid-resisting and oil-resisting, waterproof is anti-pulls waterproof compensating coaxial cable, be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of low smoke and zero halogen is anti-pulls waterproof compensating coaxial cable, and it comprises center conductor 1, skinning cortex 2, outer conductor 3, armour 4 and low smoke and zero halogen protective sleeve 7.Between described armour 4 and described low smoke and zero halogen protective sleeve 7, wrap up successively watertight composition 5, metal level 6; described watertight composition 5 is made up of the crosslinked water accepting layer of non-water accepting layer; described non-water accepting layer material is the polyurethane that adds rubber latex thread; described water accepting layer is for being made up of high water absorption wood pulp fibres; described metallic sheath 6 is to strengthen graphite line by nickel wire, and outsourcing braided steel wire forms.
Described center conductor 1 by multiply nickel plating annealed steel coppered wire to the right stranded 270 ° form, described skinning cortex 2 is for adding organic silicon ribbon of glass fibre, carbon powder particle, described outer conductor 3 is fine copper.
The permission bending radius of this cable is the outside diameter of cable 10 times.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
