Abstract
A polyethylene fiber composite band armored optical cable which comprises a cable core, an oversheath, and a polyethylene fiber composite band armor arranged between the cable core and the oversheath, wherein the polyethylene fiber composite band armor comprises a polyethylene fiber composite band and a non-woven fabric, the polyethylene fiber composite band wraps up the cable core, and the non-woven fabric wraps up the polyethylene fiber composite band. The optical cable employing a polyethylene fiber composite band armor is high in axial tensile strength, light in deadweight, small in bending radius and long in service lifetime, and overcomes the defects of high construction cost and inability of metallic materials for resisting corrosions caused by high requirement on bending radius, harsh laying conditions and heaviness of the metallic materials.
Description
Technical field
The utility model relates to a kind of optical cable, relates in particular to a kind of polyethylene fibre composite band armored optical cable.
Background technology
Existing armored optical cable generally adopts metal material to be filled armour.Its advantage is: 1, tensile strength is high, and 2, watch out for mouse and bait, 3, radially anti-pressure ability is strong.But also there is following obvious shortcoming in it: 1, in laying, the requirement to bending radius is large, laid condition is relatively harsh, 2, metal material is heavy and bring construction cost large, 3, the not anti-various corrosion of metal material.
The utility model content
The purpose of this utility model, the problem existed in order to solve above-mentioned prior art exactly, provide a kind of polyethylene fibre composite band armored optical cable.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of polyethylene fibre composite band armored optical cable, comprise cable core and oversheath, and be provided with polyethylene fibre composite band armouring between cable core and oversheath.
Described polyethylene fibre composite band armouring comprises polyethylene fibre composite band and nonwoven fabrics, and the polyethylene fibre composite band is coated on cable core, and nonwoven fabrics is coated on the polyethylene fibre composite band.
Described cable core comprises at least one optical cable.
Described cable core comprises Yi Gen center bushing pipe and is enclosed in center bushing pipe many optical cables on every side.
Described polyethylene fibre composite band by the multilaminar polyethylene fabric nonwoven cloth or/and the polyethylene fibre woven fabric is stacked forms.
Compared with prior art, the utlity model has following advantage:
One, axial tensile strength is high: the polyethylene fibre pulling strengrth is 10 times of iron and steel;
Two, conduct oneself with dignity little: density is iron and steel 1/7th;
Three, bending radius is little: polyethylene fibre composite band softness, and the bending radius of optical cable stranding can reduce, and has increased the bulk density of optical cable, has reduced the radiation difficulty;
Four, long service life: the tygon composite band in the utility model is corrosion-resistant, ageing-resistant, thereby has made up metal armouring because of the shortcoming of getting rusty, aging, corrosion was lost efficacy.
The accompanying drawing explanation
Fig. 1, Fig. 2 are the section structure schematic diagram of two kinds of polyethylene fibre composite band armored optical cables in the utility model.
Embodiment
Referring to Fig. 1, Fig. 2, polyethylene fibre composite band armored optical cable of the present utility model, comprise cable core 1 and oversheath 2, be provided with polyethylene fibre composite band armouring between cable core 1 and oversheath 2, this polyethylene fibre composite band armouring comprises polyethylene fibre composite band 3 and nonwoven fabrics 4, polyethylene fibre composite band 3 is coated on cable core 1, and nonwoven fabrics 4 is coated on polyethylene fibre composite band 3.
The polyethylene fibre that forms the polyethylene fibre composite band in the utility model is superhigh molecular weight polyethylene fibers, its pulling strengrth>=4Gpa, its density≤1.0kg/m
3, modulus>=120GPa.
Nonwoven fabrics in the utility model is heat insulation nonwoven fabrics.
Polyethylene fibre composite band in the utility model by the multilaminar polyethylene fabric nonwoven cloth or/and the polyethylene fibre woven fabric is stacked forms.
Oversheath in the utility model is by tygon, flame-proof polyethylene, Polyvinylchloride, flame-proof polyvinyl chloride, Halogen material, TPU, TPE, nylon or fire-retardant nylon extrusion moulding.
The manufacturing process of the utility model polyethylene fibre composite band armored optical cable is, first prepare cable core, then voluble wrapping polyethylene fibre composite band on cable core, followed by voluble wrapping nonwoven fabrics on the polyethylene fibre composite band, finally pass through the extrusion moulding oversheath.
The utility model optical cable is mainly the pulling strengrth of utilizing high molecular weight polyethylene fiber self, and the application of its compound substance in bulletproof stab-resistant clothes can be for the optical cable of rat-biting proof, and the alternative metals armouring reduces optical cable deadweight, bending radius.The polyethylene fibre characteristic such as ageing-resistant, corrosion in addition in addition, this has increased again the life-span of armouring greatly.Thereby make tygon composite band armored optical cable there is, axial tensile-strength advantages of higher little from heavy and light, long service life, bending radius.
