Abstract
The utility model discloses a nonmetal light is prevented that animal gnaws and is stung optical cable, including cable core and sheath, the outer transposition of cable core is prevented gnawing and is stung the layer by what comprise a plurality of GFRP, and GFRP's shape of cross section is platykurtic or fan -shaped form. The utility model has the advantages of it is following: adopt GFRP to carry out the armor, need not the inlayer sheath, have good protection against rodents and sting, prevent the effect of unfirmly closing and good corrosion resisting property, the quality is light, and stretch -proofing, anti side pressure can the reinforce to the optical cable has possessed certain pliability and counter -bending ability, the GFRP of different shapes can be in reduction GFRP's under the circumstances of guaranteeing clearance between cable core and sheath use amount, the reduction in production cost and the degree of difficulty.
Description
Technical field
This utility model is related to a kind of anti-animal of nonmetallic lightweight and bites optical cable, belong to use on power overhead network from
Hold formula optical cable.
Background technology
In optical cable installation circuit often through damaged by rats area, woods birds City Regions etc., generally such area
Optical cable a period of time after laying end, damaged by rats, the calamity of unfirmly closing can be subject to, lead to optical cable to damage.At present, it is typically employed in outside optical cable
A certain proportion of anti-rat material is added to reach mouse bite preventing function or to adopt stainless steel belt sheathed structure in sheath material
Optical cable.But As time goes on, mouse being progressively suitable for additive taste, the property feared can gradually reduce, and also can gnaw
Sting optical cable to cause to damage.And adopt the optical cable of stainless steel belt sheathed structure, mouse pass through insistent bite, outer jacket is destroyed
Afterwards, stainless steel belt directly exposed in atmosphere, the factor such as natural environment, thus cable configuration also can be destroyed.In addition stainless
The optical cable of steel steel-tape armouring structure from heavy sensation of the body and contains metal ingredient, is unfavorable for that the built on stilts of power circuit lays.
Utility model content
The purpose of this utility model is to provide a kind of light weight, stretch-proof, lateral pressure resistant ability strong, and anti-muroid, birds bite
The anti-animal of nonmetallic lightweight stinging bites optical cable.
The technical solution adopted in the utility model is：
A kind of anti-animal of nonmetallic lightweight bites optical cable, and including cable core and sheath, described cable core is outer stranded to be had by some
GFRP composition anti-bite layer it is characterised in that：The shape of cross section of described GFRP is flat or fan shape.
Preferably, also include waterstop, described waterstop is wrapped in the outer surface of cable core or the outer surface of the anti-layer that bites.
Further, described cable core is made up of two light units, three fills units and a center reinforcemen.
Further, described cable core is made up of a light unit.
Further, the surrounding of described center reinforcemen is provided with water blocking yarn.
Further, the outer surface of described sheath is provided with vitta.
Further, the medial surface of described sheath is provided with out cable.
This utility model carries out armouring using GFRP, and without internal layer sheath, concrete advantage is：
1）Due to GFRP（Glass fibre）Superfine and crisp, bite during stinging in muroid, birds, will in the glass dregs pulverizing dress
Injure the oral cavity of muroid, birds, be allowed to optical cable is produced and 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 possesses certain pliability and bending resistance.
4）GFRP of different shapes, can reduce the usage amount of GFRP in the case of ensureing gap between cable core and sheath,
Reduce production cost and difficulty.
