Abstract
The utility model relates to a communication outdoor optical cable with a termite jacket, which includes loose sleeves, optical fibers, a central reinforcing steel wire and a jacket, wherein the central reinforcing steel wire is positioned in the central position in the jacket, the multiple loose sleeves are respectively distributed in the clearance between the central reinforcing steel wire and the jacket, the multiple optical fibers are positioned as strands in the loose sleeves, the termite external jacket is further arranged on the outer side of the jacket, and galvanized twisted steel wires are arranged between the inner layer of the termite external jacket and the jacket. The communication outdoor optical cable has the advantages as follows: the tensile strength is high, and the maximum tensile strength amounts to 20000 N; the mechanical properties such as impact resistance and side pressure resistance are high, and the magnitude is enhanced; the environmental resistance; and the optical fiber is not easy to be damaged, and is suitable for being buried directly in places with large quantity of termites.
Description
Technical field
The utility model relates to a kind of optical cable, and outdoor optical cable is used in the communication of particularly a kind of anti-ant sheath.
Background technology
At the warm moist China's southern area of weather, termite badly influences the reliability service of communication line and electric power transmission line to the infringement of underground cables common plastics sheath.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, provides the communication of a kind of anti-ant sheath to use outdoor optical cable.
For achieving the above object; The utility model adopts following technical scheme: outdoor optical cable is used in the communication of a kind of anti-ant sheath, comprises loose sleeve pipe, optical fiber, center reinforcement steel wire and sheath, and the center is strengthened steel wire and is positioned at the sheath center; Some loose sleeve pipes are distributed in respectively in the gap of center reinforced wire and sheath; Some optical fiber become thigh to place in the loose sleeve pipe, and the said sheath outside also is arranged with anti-ant oversheath, is provided with zinc-plated stranded steel wire between anti-ant oversheath internal layer and the sheath.
For a kind of optimization of the utility model, the sheath internal layer is provided with pricks the line aluminium strip.
For a kind of optimization of the utility model, the center reinforced wire axially outside is coated with the PE bed course.
The utility model is compared with background technology, and its tensile strength is high, and maximum stretching resistance reaches 20000N; Mechanical propertys such as impact, side pressure are big, amplitude is strengthened; Anti-environment capacity is strong, and optical cable is difficult for being destroyed, and is fit to the more direct-burried ground of ant and uses.
Description of drawings
Fig. 1 is the schematic cross-section of anti-ant sheath communication with outdoor optical cable.
Embodiment
Embodiment 1: with reference to Fig. 1.Outdoor optical cable is used in anti-ant sheath communication; Comprise that loose sleeve pipe 1, optical fiber 2, center strengthen steel wire 6 and sheath 4; The center is strengthened steel wire 6 and is positioned at sheath 4 centers, and some loose sleeve pipes 1 are distributed in respectively in the gap of center reinforced wire 6 and sheath 4, and some optical fiber place in the loose sleeve pipe 1 for 2 one-tenth strands; Said sheath 4 outsides also are arranged with anti-ant oversheath 7, are provided with zinc-plated stranded steel wire 5 between anti-ant oversheath 7 internal layers and the sheath 4.Sheath 4 internal layers are provided with pricks line aluminium strip 3.The center reinforced wire 6 axially outside is coated with PE bed course 8.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; But these explanations; It is simple declaration to the utility model; Rather than to the restriction of the utility model, any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the utility model.
