Abstract
The invention relates to a protective jacket for a cable. The protective jacket for the cable is characterized by comprising, by weight, 18%-24% of continuous basalt fibers, 3%-6% of glass fibers, 4%-15% of carbon fibers and 58%-75% of polyethylene, wherein the continuous basalt fibers, the glass fibers and the carbon fibers are combined on the polyethylene. The protective jacket can well protect the cable, greatly improve the acid resistance and the alkali resistance of the cable and prolong the service life of the cable.
Description
Technical field
The present invention relates to a kind of cable of electric signal transmission, relate in particular to a kind of acidproof, alkali-proof protective sleeve of cable that strengthens.
Background technology
Fibre reinforced composites (Fiber Reinforced Polymer, or Fiber Reinforced Plastic, be called for short FRP) be by reinforcing fiber materials, as glass fibre, carbon fiber, aramid fiber etc., with basis material through winding, the moulding processs such as mold pressing or pultrusion and the composite material that forms.According to the difference of reinforcing material, common fibre reinforced composites are divided into glass fibre reinforced composion (GFRP), carbon fibre reinforced composite (CFRP) and aramid fiber reinforced composite (AFRP).Because fibre reinforced composites have following features: (1) specific strength is high, and specific modulus is large; (2) material property has designability: (3) corrosion resistance and excellent in durability; (4) thermal coefficient of expansion and concrete close.These features make FRP material can meet modern structure to greatly across the needs of, towering, heavily loaded, high-strength light and job development under mal-condition, also can meet the requirement of modern architecture construction industrialization development, be therefore applied to more and more widely in the fields such as various civil buildings, bridge, highway, ocean, hydro-structure and underground structure simultaneously.
Cable is normally by the cable of several or the stranded similar rope forming of several groups of wires (at least two every group), mutually insulated between every group of wire, and often round Yi Gen center, be twisted into, whole outside is surrounded by the cover layer of high-insulation.Be erected at aerial more or be contained in underground, water-bedly, for telecommunication or electric power, carrying.
Cable is mainly comprised of following 4 parts.1. conducting wire center: make with high conductivity material (copper or aluminium).According to laying the requirement of service condition to the soft degree of cable, every line heart may by solid conductor or multiple conducting wires is stranded forms.2. insulating barrier: the insulating material as cable should have high insulation resistance, high breakdown field strength, low dielectric loss and low dielectric constant.In cable, conventional insulating material has oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber etc.Cable is often with insulating material classification, such as oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc.3. sealing sheath: the protection insulated wire heart is avoided the damage of machinery, moisture, moisture, chemical substance, light etc.For the insulation of moisture-sensitive, generally adopt lead or aluminium extrusion sealing sheath.4. protect cover layer: in order to protect sealing sheath to avoid mechanical damage.General galvanized steel strip, steel wire or copper strips, the copper wires etc. of adopting surround sheath outer (title armoured cable) as armor, and armour plays electric field shielding simultaneously and prevents external electromagnetic wave interference.For fear of steel band, steel wire, be subject to the corrosion of medium around, generally at their outside pitch or hold macerated jute layer or extruded polyethylene, polyvinyl chloride cover.
In complicated environments such as subsea, cable will be subject to washing away of seawater at any time, adds seawater component complexity, and corrosion strength is strong, and cable is easily subject to the corrosion of seawater, and greatly shorten useful life.
Summary of the invention
In order to overcome existing cable, cannot reach the defect that environments such as subsea requires, the invention provides a kind of cable protective sleeve, on existing cable, put this protective sleeve; cable is well protected; greatly improve the acidproof of cable, alkaline-resisting ability, the useful life of prolongation cable.
A cable protective sleeve, is characterized in that: comprise continuous basalt fiber, glass fibre, carbon fiber and polyethylene, continuous basalt fiber, glass fibre and carbon fiber are compounded on polyethylene, by weight percentage:
Continuous basalt fiber: 18% ~ 24%
Glass fibre: 3% ~ 6%
Carbon fiber: 4% ~ 15%
Polyethylene: 58% ~ 75%.
By weight percentage:
Continuous basalt fiber: 20% ~ 22%
Glass fibre: 4% ~ 5%
Carbon fiber: 8% ~ 10%
Polyethylene: 66% ~ 72%.
The present invention has the following advantages:
Reinforced sheath of the present invention is owing to being to be compounded on polyethylene by continuous basalt fiber, glass fibre and carbon fiber, continuous basalt fiber is acid resistance and the alkali resistance of sheath greatly, high temperature resistance and the cryophylactic performance of sheath have also been increased simultaneously, sheath is enclosed within on cable, can make cable for complicated environments such as subsea, can bear the corrosion of seawater and wash away, greatly having extended the useful life of cable.
