Description

Layer-twisted type is fire-retardant, corrosion protection, mouse bite preventing communication outdoor optical cable
Technical field
Disclosed by the inventionly be that a kind of layer-twisted type is fire-retardant, corrosion protection, mouse bite preventing communication outdoor optical cable, be to the improvement of existing communication with the outdoor optical cable structure.
Background technology
Along with the development of telecommunications, communication constantly increases with the application quantity of outdoor optical cable, simultaneously, the requirement that is laid in outdoor communications optical cable also constantly is particular about.For example: to human settlements compact district, oil field, electric power, abominable, the special area of geographical environment, the serious occasion laying optical cable of mouse insect pest, though anti-high temperature, anti-corrosion, the protection against rodents insect bite factor of chewing is more and more realized by people and pay attention to, but present outdoor optical cable still is confined to the structure that steel band or wrinkle steel band are closed in vertical cladding outside cable core, cause optical cable can't possess resistance flammability, anticorrosive property, protection against rodents worm property, in the future long-term security is used bring hidden danger.
The related half-dry type layer-twisted type communications optical cable of Chinese patent CN2510876Y as shown in Figure 1 and Figure 2, by be equipped with the loose sleeve pipes 7 of several of optical fiber 5 and or add partially filled rope 2 and be twisted into cable core with " SZ " at strengthening core 4, the outer wrapped polyester band 9 of cable core, wrapped steel or aluminium-plastic tape 3 outside polyester band 9, add sheath 1 at it again, and between cable core and polyester band 9 and between steel or aluminium-plastic tape 3 and the polyester band 9 the institute gapped in the filling hot melt adhesive 10.That this technical scheme is put to the proof with it and be the water blocking tape layer 9 that original polyester band 6 is replaced by low liberation of hydrogen used instead with original mineral ointment 8 by the prior art difference that Fig. 1 reflected and become to hang down liberation of hydrogen hot melt adhesive 10.Thereby this patent technique effect that will reach is presented as can be known: 1, prevent because of H +Infiltration and cause decay to optical fiber; 2, improve bond strength between cable core and water blocking tape layer 9, water blocking tape layer 9 and the composite steel-plastic belt 3 with hot melt adhesive not volatile and that have a strong adhesive force; 3, promote block-water effect; 4, to need when the laying optical cable to avoid in the past causing influence to form half dry type to human body, environment with detersive.Still there is following problem in the optical cable of this structure:
1, if hot melt adhesive 10 is liquid, then still have flowability and volatility, this patent is solid-state obviously, because according to normal temperature, hot melt adhesive 10 should be solid-state.But solid-stately make that the overall bulk softness of product is low, in construction, need extremely careful in the laying optical cable, not so can cause its outer steel or aluminium-plastic tape 3 jackknifings of cladding because of factors such as bendings, and and then the jackknifing of bringing disaster to its outer field restrictive coating 1, more and, in the installation fusion process of optical cable, a plurality of loose sleeve pipes 7 must be separated from each other, and after having used hot melt adhesive, cable core knot and become an integral body, add that the bonding of hot melt adhesive is very firm, certainly will adopt speciality tool to come a minute shredding sleeve pipe 7, so that welding, in view of this, hot melt adhesive is a very careful usefulness or seldom used and even exempt from usefulness.
2, steel or aluminium-plastic tape 3 are plastic-coated band or plastic-blasting band, in case moisture content then can cause its corrosion protection result rapid drawdown even the moisture content of trace infiltrates, influence long-term safety and use.
3, owing between steel or aluminium-plastic tape 3 and restrictive coating 1, lack necessary transition bed, therefore no matter be the effect that mutually combines of the two, the ability of still whole high temperature resistant, resistant to rust, anti-mouse insect bite etc. all is very fragile, and optical cable many reasons of damaging are in short-term caused by these factors exactly at present.
Again, Chinese patent CN2354216Y is disclosed to block water, high flame resistance, low smoke Halogen power cable with cross-linked polyethylene insulation, as shown in Figure 3, it be the screen layer 2 that becomes cable core 1 outer set gradually insulation course 3, insulation screen 4, steel band screen layer 5, packed layer 6 (this packed layer 6 comprise intersection around prick waterproofing rope 11, packed layer 10 blocks water), separation layer 7, flame-retardant layer 12, steel-tape armouring layer 8, oversheath 9, the water intrusion that takes place probably of blocking-up becomes the interior passage of cable core 1 by this.This structure is not suitable for also can't transplanting or using for reference on the optical cable, at first, because of packed layer 6 is to constitute around bundle waterproofing rope 11, packed layer 10 by intersecting, expand though help meeting water, blocking-up cable embedding crack is in order to blocking water, and it is with respect to for mineral ointment, the waterstop effect will be inferior very much, the packed layer 6 that adds this structure is easily aging, and the resistance effect life-span is very short, should not be used for the protection to the optical cable core periphery; Secondly, the starting point of this structure is to block water, and chews for corrosion protection, protection against rodents insect bite and can't play inhibiting effect, and in the practical application of optical cable, and more and more problem is chewed in high temperature resistant exactly, the anti-corrosion of the problem that draws attention for people, protection against rodents insect bite.
Summary of the invention
The objective of the invention is to provide a kind of corrosion protection, protection against rodents insect bite chew and the flame retardant effect excellence, be suitable for that the layer-twisted type that long-term safety uses is fire-retardant, corrosion protection, mouse bite preventing communication outdoor optical cable.
The objective of the invention is to reach like this; a kind of layer-twisted type is fire-retardant; corrosion protection; mouse bite preventing communication outdoor optical cable; comprise: one has the many sleeve pipes 3 that are included in one or more optical fiber 1 wherein centers on the cable core 6 that a central reinforce member 4 is twisted into; be contained in the packing material 2 in the described sleeve pipe 3; one deck surrounds the waterstop 7 outside the described cable core 6; be filled in the filling glue 5 and one that the nationality in all spaces between waterstop 7 and the cable core 6 plays buffer action and be positioned at outermost flame-retardant layer 12; the described waterstop 7 outer clad aluminum belts 8 that are provided with; the clad aluminum belt 8 outer tygon protective seams 9 that are extruded with; the tygon protective seam 9 outer one deck stainless steel bands 10 that coat; the stainless steel band 10 outer tack coats 11 again that squeeze, flame-retardant layer 12 is extruded in outside the tack coat 11.
Stainless steel band 10 of the present invention is a stainless steel 304.
Stainless steel band 10 of the present invention is a stainless steel 316.
