Abstract

The utility model relates to a non-metallic optical cable of central tube formula, including loose sleeve pipe, setting up at the intraductal optic fibre of loose sleeve, fill waterproof fine cream, the cover between loose sleeve pipe and optic fibre and establish the oversheath layer in loose sleeve pipe periphery loose sleeve pipe and oversheath layer between be equipped with aramid yarn enhancement layer, owing to be equipped with aramid yarn enhancement layer between loose sleeve pipe and oversheath layer, make the utility model discloses an optical cable bending property is better, and tensile strength is higher, and weight is lighter, consequently more suitably is applied to high-voltage electric occasion.

Description

The central tubular non-metallic optical fiber cables
Technical field
The utility model relates to a kind of central tubular non-metallic optical fiber cables.
Background technology
Along with the arrival of information age, the conveying capacity of information becomes explosion type ground to increase.As the effective means of high capacity, long Distance Transmission, optical fiber cable has obtained using in large quantities.The center type non-metallic optical fiber cables is usually used in the communication between the building, existing center type non-metallic optical fiber cables comprises a loose sleeve pipe, be arranged on the optical fiber in the loose sleeve pipe, be filled in the fine cream of waterproof between loose sleeve pipe and the optical fiber, be enclosed with external sheath layer in loose sleeve pipe periphery, between external sheath layer and loose sleeve pipe, also be provided with the nonmetallic materials enhancement Layer, but the tensile strength of this kind optical cable is relatively poor, should not uses in the high-tension electricity occasion.
Summary of the invention
The utility model purpose is to provide a kind of tensile strength the higher central tubular non-metallic optical fiber cables that is suitable for the application of high-tension electricity occasion in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of central tubular non-metallic optical fiber cables, comprise loose sleeve pipe, be arranged on optical fiber in the loose sleeve pipe, be filled in the fine cream of waterproof between loose sleeve pipe and the optical fiber, be set in the external sheath layer of described loose sleeve pipe periphery, between described loose sleeve pipe and external sheath layer, be provided with the aramid yarn enhancement Layer.
Further, it also comprises the weight body that is fixedly connected with described external sheath layer, described weight body comprises restrictive coating, is arranged on the steel strand wires in the restrictive coating, owing to be provided with weight body, when setting up installation, weight body is directly installed on the electric pole, need not to establish in addition steel strand wires and cable clip, both can shorten the man-hour of constructing, the trouble in can avoiding again constructing.
Described external sheath layer and restrictive coating are one-body molded.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: owing to be provided with the aramid yarn enhancement Layer between loose sleeve pipe and external sheath layer, make that optical cable bending property of the present utility model is better, tensile strength is higher, weight is lighter, the therefore relatively more suitable high-tension electricity occasion that is applied to.
Description of drawings
Accompanying drawing 1 is the utility model longitudinal sectional view;
Wherein: 1, loose sleeve pipe; 2, optical fiber; 3, the fine cream of waterproof; 4, external sheath layer; 5, aramid yarn enhancement Layer; 6, weight body; 61, restrictive coating; 62, steel strand wires.
Embodiment
Below in conjunction with accompanying drawing, describe particular content of the present utility model in detail for example:
Central tubular non-metallic optical fiber cables as shown in Figure 1, comprise loose sleeve pipe 1, in loose sleeve pipe 1, be provided with the optical fiber 2 of many coated mistakes, be filled in the fine cream 3 of waterproof between loose sleeve pipe 1 and the optical fiber 2, periphery from loose sleeve pipe 1 is enclosed with aramid yarn enhancement Layer 5 and external sheath layer 4 successively, external sheath layer 4 is a black low density polyethylene sheath, owing between loose sleeve pipe 1 and external sheath layer 4, be provided with aramid yarn enhancement Layer 5, make optical cable of the present utility model have stronger tensile strength, bending property is better, and aramid yarn weight is lighter, therefore makes that the weight of whole optical cable is lighter.
For the needs that set up, the utility model optical cable also comprises a weight body 6, this weight body 6 comprises a restrictive coating 61, is arranged on the steel strand wires 62 in the restrictive coating 61, restrictive coating 61 is connected with external sheath layer 4 outsides, when making, external sheath layer 4 can be one-body molded with restrictive coating 61, in the present embodiment, oversheath 4 is integrally formed as great circle and roundlet and coupling part with restrictive coating 61, in great circle, outside to inside set gradually aramid yarn enhancement Layer, loose sleeve pipe, optical fiber, steel strand wires are placed little circular portion.
