The current many weak points of power cable presence, such as cable UV radiation when using are aging, heat aging property is poor,
Expensive, cable does not have the structure of good softness, and but some cables have the structure of softness do not have enough anti-tensiles strong
Degree, bending resistance, construction wrong causes crust injury or abrasion etc., runs in long-term high voltage electric field, and its surface is perishable
Erosion, and the optical cable of oversheath flat smooth can efficiently reduce galvano-cautery and extend the life-span, therefore, propose one for the problems referred to above
Plant optical fiber handling cable.
Utility model content
The purpose of this utility model is to provide a kind of optical fiber handling cable, with solve in above-mentioned background technology propose ask
Topic.
For achieving the above object, this utility model provides a kind of following technical scheme: optical fiber handling cable, protects including outer
Set, described oversheath is wrapped in the surface of aramid fiber layer, and thermal insulation layer is installed in the inside of aramid fiber layer；Described thermal insulation layer is wrapped in
The surface of sheath, and sheath is wrapped in the surface of water blocking layer；The inside center setting center reinforcemen of described water blocking layer, and
The surrounding of center reinforcemen is uniformly arranged Loose tube, and Loose tube is located at the inside of water blocking layer；The inner homogeneous of described Loose tube
Setting optical fiber.
Preferably, described Loose tube is five, and Loose tube is wrapped in the outer surface of described center reinforcemen.
Preferably, the cross-sectional area of described thermal insulation layer is more than the cross-sectional area of oversheath.
Preferably, described aramid fiber layer is identical with the cross-sectional area of sheath.
Preferably, the cross-sectional area of described water blocking layer be more than sheath cross-sectional area, and the centrage of water blocking layer with
The centrage of heart reinforcement is located on the same line.
Compared with prior art, the beneficial effects of the utility model are: do not contain any metal in this kind of fiber optic cable
Material, all insulation structure and higher pressure index, are conducive to erection construction on the overhead power line of charging operation, not shadow
Ring circuit to run, can be born compared with high tension using the high anti-synthetic fibre material of tensile strength, meet the large span of overhead power line
Require, unfirmly closing and artificial gunslinging can be prevented, thermal coefficient of expansion is less again, when temperature change is very big, the radian of lightguide cable link
Vary less, and it is lightweight, its shoe ice and wind lotus are also less.
