Abstract
The invention discloses a novel nonmetallic armored enhanced self-supporting optical cable comprising a cable core, an aramid fiber layer, a water-blocking tape layer, and an outer sheath. An anti-bite layer composed of a plurality of GFRP pieces is stranded outside the cable core, the water-blocking tape layer coats the anti-bite layer, and the cross section of GFRP is flat or fan-shaped. The optical cable, which is armored with GFRP, has the specific advantages as follows: (1) GFRP (Glass Fiber Reinforced Plastic) is extremely thin and fragile, and crushed glass pieces wound injure the oral cavities of rats and birds when rats and birds bite the optical cable, so rats and birds have a fear of the optical cable, and an anti-bite and anti-pecking effect is achieved; (2) the optical cable has excellent corrosion resistance; (3) the optical cable is light and tensile, has strong ability to resist lateral pressure, and has certain flexibility and bending resistance; and (4) by use of GFRP of different shapes, GFRP consumption is reduced under the condition of ensuring the gap between the cable core and the outer sheath, and the production cost and difficulty are reduced.
Description
Technical field
The present invention relates to a kind of novel metalloid armouring enhancement mode self-support cable, belong to the self-support cable used on power overhead network.
Background technology
Often through damaged by rats area, woods birds City Regions etc. in optical cable installation circuit, the generally optical cable in such area a period of time after laying end, optical cable can be caused to damage by damaged by rats, the calamity of unfirmly closing.
At present, it is typically employed in cable outer sheath material and adds a certain proportion of anti-rat material, reach mouse bite preventing function or use the optical cable of steel-tape armouring structure.But As time goes on, mouse is progressively suitable for additive taste, the property feared can gradually reduce, and the optical cable that also can bite causes to damage.And using the optical cable of steel-tape armouring structure, mouse is bitten by insistent, after being destroyed by outer jacket, some thickness of strips are inadequate, the most quickly stung bad by mouse, or steel band is the most exposed in atmosphere, meeting corrosion after steel band oxidation, thus optical cable endothecium structure also can be destroyed.In addition the optical cable of steel-tape armouring structure is from heavy sensation of the body and containing metal ingredient, is unfavorable for that the built on stilts of power circuit lays.
Summary of the invention
It is an object of the invention to provide a kind of light weight, stretch-proof, lateral pressure resistant ability strong, and anti-muroid, birds bite the novel metalloid armouring enhancement mode self-support cable stung.
The technical solution used in the present invention is:
A kind of novel metalloid armouring enhancement mode self-support cable, including cable core, aramid layers, water blocking tape layer and oversheath, described cable core is outer stranded by the anti-layer that bites being made up of some GFRP, and described water blocking tape layer is coated on to be prevented biting outside layer, and the shape of cross section of described GFRP is flat or fan shape.
Further, also including that inner sheath, described inner sheath are coated on outside cable core, the described anti-layer that bites is stranded in outside inner sheath, and described aramid layers is coated between water blocking tape layer and oversheath.
Further, also including that middle sheath, described aramid layers are coated on outside inner sheath, described middle sheath is coated on outside aramid layers, and the described anti-layer that bites is stranded in outside middle sheath.
Further, described aramid layers is coated between water blocking tape layer and oversheath.
The present invention uses GFRP to carry out armouring, and concrete advantage is:
1) due to GFRP(fiberglass reinforced plastics) superfine and crisp, bite during stinging muroid, birds, the oral cavity of muroid, birds will be injured in the glass dregs pulverizing dress, be allowed to optical cable is produced fear sense, can reach mouse bite preventing, the effect of anti-unfirmly closing.
2) there is excellent decay resistance.
3) light weight, stretch-proof, lateral pressure resistant ability are strong, and optical cable has possessed certain pliability and bending resistance.
4) difform GFRP, it is possible to ensureing to reduce in the case of gap between cable core and oversheath the usage amount of GFRP, reducing production cost and difficulty.
