Abstract
The invention discloses an air-blown optical cable easy to install. The air-blown optical cable comprises a cable core (1) and an inner sheath (2) that wraps the cable core (1). The cable core (1) includes a reinforcement member (3) and six fiber units (4) that are arranged to surround the reinforcement member (3). Each fiber unit (4) comprises a fiber (5) and a loose tube (6) that wraps the fiber (5). A plastic-coated aluminium belt (7) coats the inner sheath (2), and an outer sheath (8) coats the plastic-coated aluminium belt (7). The external part of the outer sheath (8) is equipped with convex patterns. The beneficial effects of the air-blown optical cable are that the convex patterns are arranged on the surface of the optical cable so that the friction between the optical cable and an installation pipe is reduced and the installing speed is substantially increased.
Description
Technical field
The present invention relates to a kind of easy-to-install air-blowing optical cable.
Background technology
Optical cable is mainly by light transmitting fiber (thin as the glass fiber of hair) and plastic protective sleeve pipe and plastic peel formation.Optical cable is the main delivery means of the various Information Networks of current information society.
The system of laying of optical cable comprises overhead type, direct burial and duct type, duct type is generally air-blowing optical cable mounting means, adopt mode that high pressure draught blows by optical cable lowering in the silicon core pipe of pre-plugged, blow cable machine by high pressure, pressurized air is at a high speed blown into silicon core pipe, high pressure draught promotes sealing gland piston, the sealing gland piston that is connected to like this end of cable forms the uniform pulling force of a setting to optical cable, in this, blow cable machine hydraulic track conveying mechanism clamping optical cable is fed forward simultaneously, erection mode is very simple and practical like this, although but existing optical cable surface is all smooth, but because larger with silicon core pipe surface of contact, rub still very large, blow very and be not easy, speed is very slow.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, and a kind of easy-to-install air-blowing optical cable is provided, solve existing air-blowing optical cable because and between mounting pipe, rub excessively, cause the very slow problem of installation rate.
The present invention is achieved through the following technical solutions: easy-to-install air-blowing optical cable, the inner sheath that comprises cable core and parcel cable core, described cable core comprises reinforcement and the fiber unit arranging around reinforcement, the quantity of described fiber unit is 6, fiber unit comprises the loose sleeve pipe of optical fiber and parcel optical fiber, described inner sheath is wrapped with plastic-coated aluminium strip, and plastic-coated aluminium strip is also enclosed with oversheath outward, and the outer setting of described oversheath has burr.
Described burr is linear pattern, and direction is consistent with optical cable.
Between described cable core and plastic-coated aluminium strip, be provided with waterstop.
In described cable core Nei gap, be filled with greasy for preventing water.
In described loose sleeve pipe, be also filled with greasy for preventing water.
The invention has the beneficial effects as follows: the surface at optical cable arranges burr, reduced and mounting pipe between friction, installation rate is significantly improved.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As shown in Figure 1 and Figure 2, easy-to-install air-blowing optical cable, the inner sheath 2 that comprises cable core 1 and parcel cable core 1, described cable core 1 comprises reinforcement 3 and the fiber unit 4 arranging around reinforcement 3, the quantity of described fiber unit 4 is 6, and fiber unit 4 comprises the loose sleeve pipe 6 of optical fiber 5 and parcel optical fiber 5, and described inner sheath 2 is wrapped with plastic-coated aluminium strip 7, plastic-coated aluminium strip 7 is outer is also enclosed with oversheath 8, and the outer setting of described oversheath 8 has burr 9.
Described burr 9 is linear pattern, and direction is consistent with optical cable.
Between described cable core 1 and plastic-coated aluminium strip 7, be provided with waterstop 10.
In described cable core 1 Nei gap, be filled with greasy for preventing water.
In described loose sleeve pipe 6, be also filled with greasy for preventing water.
