Description

The built on stilts fire prevention of self-bearing type aluminium core composite cable

Technical field

The utility model relates to the optical cable technology field, and it is a kind of have fire prevention, built on stilts aluminium core composite cable of preventing fires of self-bearing type heat-resisting, fire resistance in definite saying.

Background technology

Because China's fire disaster constantly takes place, cause great harm for people's productive life at present.Electricity consumption and security against fire receive much attention during the acceptance of work, and the composite rope of therefore preventing fires has the very wide market prospects that expand; Optoelectronic composite cable on the market is used copper conductor more, and electric conductivity is better, has but that cost is higher relatively, a Heavy Weight, the relatively poor shortcoming of bending property.Cost is low, in light weight, the advantage of good bending property and the built on stilts fire prevention of self-bearing type aluminium core composite rope has.But in use also there are some drawbacks.In construction, have ointment like loose sleeve pipe and drop onto contaminated environment on the ground, the optical fiber in the loose sleeve pipe needs could use behind the fusion splice, influences the engineering time; Aluminium core conduction loss is big, bad welding.

Summary of the invention

The purpose of the utility model provides the built on stilts fire prevention of a kind of self-bearing type aluminium core composite cable, has that cost is low, in light weight, characteristics of fire prevention, heat-resisting, fire-retardant, good bending property.Technical scheme is following: the built on stilts fire prevention of self-bearing type aluminium core composite cable; It comprises sheath, lead, cable core filled composite, reinforcement bed course, reinforcement, optical fiber, pine cover filled composite, loose sleeve pipe, moisture-proof layer; Optical fiber has pine cover filled composite in the loose sleeve pipe in loose sleeve pipe, it is characterized in that: loose sleeve pipe and the aluminum conductor that is with aluminum conductor bed course and fireprotection layer center on be stranded in reinforcement around; The outside is wrapped up by band; Band is outward a moisture-proof layer, and moisture-proof layer is outward 8 font fire retardant jackets, is steel strand wire in the small diameter bore of fire retardant jacket.Gasket for packing is arranged around the reinforcement.Yarn, inner cushion layer and the nonmetal auxiliary stiffener of bundle arranged in the band.

The utility model has the advantages that:

1, fire-resistant, high temperature resistant, the tool fire protecting performance; The operating state that still can keep normal power supply with the naked light burning more than 4 hours;

2, have fire resistance, can stop or delay fire spreading with the naked light combustion;

Have more fail safe when 3, burning, the smog light transmittance is high during burning, and does not contain halogen element in the smog;

The serial problem that 4, generally could solve with many cables can replace with a composite rope at this;

5, cost low, in light weight, be easy to built on stilts laying;

6, can satisfy long Distance Transmission, also sectional uses;

7, the physical characteristic that still keeps optical cable is like anti-collapse, stretching etc.;

8, client's purchase cost is low, and operating expenses is low, and the networking expense is low;

9, have superior bending property and good anti-side pressure performance, easy construction;

10, multiple transmission technology is provided simultaneously, strong with adaptability height, the extensibility of equipment, product is widely applicable;

11, provide huge bandwidth to insert, guarantee the remote power feeding demand;

12, practice thrift cost, optical fiber as the usefulness of reserving to the family, has been avoided the secondary wiring;

13, solve equipment electrical problem (avoiding repeating to lay supply line) in the networking;

14, according to ports such as customer requirement FC/SC/ST.

Embodiment

The built on stilts fire prevention of self-bearing type aluminium core composite cable; It comprises sheath, aluminum conductor, guy wire, cable core filled composite, reinforcement bed course, reinforcement, optical fiber, pine cover filled composite, loose sleeve pipe, moisture-proof layer, and optical fiber 3 has pine cover filled composite 1 in the loose sleeve pipe 2 in loose sleeve pipe 2; Pine sleeve pipe 2 and the aluminum conductor 10 that is with aluminum conductor bed course 12 and fireprotection layer 11 around be stranded in reinforcement 4 around; The outside is by band 9 wrapping, pine cover filled composites 1 in the loose sleeve pipe 2, and band 9 is outer to be moisture-proof layer 7; Outside the moisture-proof layer 7 is 8 font fire retardant jackets 13, is steel strand wire 14 in the small diameter bore of fire retardant jacket 13.Has gasket for packing 6 around the reinforcement 4.Have yarn, inner cushion layer and the nonmetal auxiliary stiffener of bundle in the band 9.Reinforcement bed course 5 is arranged outside the reinforcement 4.

The built on stilts fire prevention of self-bearing type aluminium core composite rope selects for use the layer-twisted type structure to produce:

1, optical fiber pine cover lining

For not receiving external action, protection optical fiber outside optical fiber coating, do not squeeze into the process of one deck suitable plastic pine cover and filled composite resilient coating.

2, aluminum conductor insulating barrier sheath

Aluminum steel carries out the flame-proof material sheath after adding fireprotection layer, our employed main insulating material is a low-smoke halogen-free polyolefin, utilizes extruder to accomplish the copper line surface sheath.

3, stranding

Stranded with loose sleeve pipe, aluminum conductor, presumable gasket for packing, reinforcement nature to together, excessive for preventing yarn-binding tension, be adjusted to inertial states, purpose be element is closed as a whole.

4, oversheath

Cable core becomes 8 font sheaths with steel strand wire.The restrictive coating of optical cable is used for protecting cable core, makes cable core, aluminum conductor avoid the influence of extraneous mechanism and environmental condition, and we select the low smoke and zero halogen sheath material for use.

Briefly at first with optical fiber pine cover protection, surperficial sheath flame retardant insulation material behind the wrapped fireprotection layer of aluminum conductor is twisted into cable core with steel wire or FRP reinforcement with aluminum conductor and loose sleeve pipe and presumable gasket for packing again, and cable core is become finished product behind the 8 font sheaths with steel strand wire.Performance is identical with photoelectricity mixing cable with Access Network, and the built on stilts fire prevention of self-bearing type aluminium core composite cable is easier to built on stilts laying, and cost is low, in light weight, has better fire retardant performance.
