Abstract

The utility model discloses a novel non - metal armor enhancement mode self -bearing type optical cable, including cable core, aramid fiber layer, block water lacing and oversheath, the outer transposition of cable core is prevented gnawing and is stung the layer by what comprise a plurality of GFRP, block water the lacing cladding prevent gnawing sting the layer outside, GFRP's shape of cross section is platykurtic or fan -shaped form. The utility model discloses a GFRP carries out the armor, and concrete advantage is: 1 )Because GFRP ( glass fibre reinforced plastics ) is superfine and fragile, bites muroid, birds and stings the in -process, be the oral cavity that the glass residue who smashes the dress will injure muroid, birds, make it to produce to fear to the optical cable to feel, can reach the effect that the protection against rodents stings, prevents the unfirmly closing. 2 )Good corrosion resisting property has. 3 )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. 4 )The GFRP of different shapes can be in reduction GFRP's under the circumstances of guaranteeing clearance between cable core and oversheath use amount, the reduction in production cost and the degree of difficulty.

Description

A kind of novel metalloid armouring enhancement mode self-support cable

Technical field

This utility model is related to a kind of novel metalloid armouring enhancement mode self-support cable, belongs to and makes on power overhead network Self-support 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 cable outer sheath material and adds a certain proportion of anti-rat material, to reach mouse bite preventing Function or the optical cable using steel-tape armouring structure.But As time goes on, mouse being progressively suitable for additive taste, The property feared can gradually reduce, and the optical cable that also can bite causes to damage.And adopting the optical cable of steel-tape armouring structure, mouse passes through insistent Bite, after outer jacket is destroyed, some thickness of strips not, are also stung bad quickly by mouse, or steel band directly exposed in sky In gas, 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 contain metal ingredient, it 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 novel metalloid armouring enhancement mode self-support cable stung.

The technical solution adopted in the utility model 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 outer stranded by the anti-layer that bites being made up of some GFRP, described water blocking tape layer be coated on anti-bite outside layer, described The shape of cross section of GFRP is flat or fan shape.

Further, also include inner sheath, described inner sheath is coated on outside cable core, the described anti-layer that bites is stranded in inner sheath Outward, described aramid layers are coated between water blocking tape layer and oversheath.

Further, also include middle sheath, described aramid layers are coated on outside inner sheath, described middle sheath is coated on aramid layers Outward, the described anti-layer that bites is stranded in outside middle sheath.

Further, described aramid layers are coated between water blocking tape layer and oversheath.

This utility model carries out armouring using GFRP, and concrete advantage is：

1）Due to GFRP（Fiberglass reinforced plastics）Superfine and crisp, bite during stinging in muroid, birds, in pulverizing dress Glass dregs will injure the oral cavity of muroid, birds, is allowed to optical cable is produced and fears 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 use of GFRP in the case of ensureing gap between cable core and oversheath Amount, reduces production cost and difficulty.
