Abstract

The utility model discloses a mouse-proof pipeline rubber-insulated optical fiber, comprising a protective cover (1), reinforcement members (2), a fiber (3), a water-blocking tape (4), an aluminum tape (5), an HPE protective layer (6) and a nylon oversheath (7). The fiber (3) is positioned in the innermost layer, the reinforcement members (2) are distributed in the circumference of the fiber (3), and the protective layer (1) wraps the fiber (3) and the reinforcement members (2); the water-blocking tape (4) is positioned outside the protective layer (1) and wraps the protective layer (1); and the aluminum tape (5), the HPE protective layer (6) and the nylon oversheath (7) are successively arranged outside the water-blocking tape (4), wherein the aluminum tape (5) wraps the water-blocking tape (4), the HPE protective layer (6) wraps the aluminum tape (5), and the nylon oversheath (7) wraps the HPE protective layer (6). According to the utility model, damages of mice and other rodent to the optical fiber can be prevent, so that the optical cable is more stable, and post maintenance cost is decreased.

Description

Protection against rodents pipeline covered wire cable

Technical field

The utility model relates to the outdoor optical cable manufacturing technology, particularly a kind of pipeline covered wire cable with protection against rodents function.

Background technology

In recent years, the optical fiber access market of China presented good growth momentum, and optical fiber inserts the focus that has become in the optical communication field.Insert in the engineering at optical fiber, outside run also is very important and complicated link, especially adopts outdoor built on stilts wire laying mode.Yet, along with constantly carrying out of urban construction, cable lays and is required hiddenization gradually, therefore usually adopt pipeline or buried mode to carry out, the bending property of conventional outdoor optical cable, the demand that tensile property can not satisfy outside run, and because appearance such as mouse is often arranged in the pipeline, conventional outdoor optical cable can't prevent effectively that mouse is to the destruction of optical cable.

The utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of pipeline covered wire cable with protection against rodents function is provided.

The purpose of this utility model is achieved through the following technical solutions: protection against rodents pipeline covered wire cable, it comprises sheath, reinforcement, optical fiber, waterstop, aluminium strip, HPE sheath and nylon oversheath, optical fiber is positioned at the innermost layer, reinforcement is distributed in the periphery of optical fiber, sheath coats optical fiber and reinforcement, waterstop is positioned at the sheath skin, and sheath is wrapped up, and waterstop is provided with aluminium strip, HPE sheath and nylon oversheath and outer its internal layer that coats outward successively.

Wherein, described HPE is the ultra high molecular polyethylene material, and sheath is made by low smoke halogen-free flame-retardant polyolefin.

The utlity model has following advantage:

One, the utility model adopts nylon as oversheath, has hardness height, good toughness, high temperature resistant and fire-retardant characteristics;

Two, the utility model has reduced the destruction of rodents such as mouse to optical cable, makes optical cable more stable, has also reduced the maintenance cost in later stage simultaneously.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Among the figure, 1-sheath, 2-reinforcement, 3-optical fiber, 4-waterstop, 5-aluminium strip, 6-HPE sheath, 7-nylon oversheath.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described, protection domain of the present utility model is not limited to the following stated:

As shown in Figure 1, protection against rodents pipeline covered wire cable, it comprises sheath 1, reinforcement 2, optical fiber 3, waterstop 4, aluminium strip 5, HPE sheath 6 and nylon oversheath 7, optical fiber 3 is positioned at the innermost layer, reinforcement 2 is distributed in the periphery of optical fiber 3, and sheath 1 coats optical fiber 3 and reinforcement 2 get up, and waterstop 4 is positioned at sheath 1 skin, and sheath 1 wrapped up waterstop 4 outer aluminium strip 5, HPE sheath and nylon oversheath 7 and outer its internal layers that coat of being provided with successively.

Claims

1. protection against rodents pipeline covered wire cable, it is characterized in that: it comprises sheath (1), reinforcement (2), optical fiber (3), waterstop (4), aluminium strip (5), HPE sheath (6) and nylon oversheath (7), optical fiber (3) is positioned at the innermost layer, reinforcement (2) is distributed in the periphery of optical fiber (3), sheath (1) coats optical fiber (3) and reinforcement (2) get up, waterstop (4) is positioned at sheath (1) skin, and sheath (1) wrapped up the outer aluminium strip (5) that is provided with successively of waterstop (4), HPE sheath (6) and nylon oversheath (7) and outer its internal layer that coats.
