Abstract
The utility model relates to a loosely shielded layer-stranding cable, which comprises optical fibers, a sheath, loosely shielded tubes, a central strengthening column and fillers, wherein the center in the sheath is axially provided with the central strengthening column, the loosely shielded tubes are distributed around the central strengthening column in the sheath, the loosely shielded tubes are provided with a plurality of optical fibers, the fillers are respectively filled in a gap between the loosely shielded tubes and the optical fibers and a gap between the loosely shielded tubes and the sheath, the sheath comprises an internal sheath, an external sheath and an aramid yarn strengthening element positioned between the internal sheath and the external sheath, the central strengthening column is positioned in the center of the internal sheath, and the loosely shielded tubes are positioned around the central strengthening column in the internal sheath. The loosely shielded layer-stranding cable disclosed by the utility model has the advantages of high strength, light weight, small cross section, convenience in erection and construction, and the like.
Description
Technical field
The utility model relates to a kind of optical fiber cable, particularly a kind of loose sleeve layer strand type optical cable.
Background technology
Because optical fiber cable is self-support cable, thereby it is in stress for a long time after setting up, and when climate change, also usually can receive higher load, and this just requires optical fiber cable to have fabulous tensile property.Optical fiber cable is again a nonconductive optical fiber cable, does not wherein have hardware, and its main stiffener is the aramid fiber silk, and in order to reach enough pulling force and to alleviate optical cable weight as far as possible, the layout of aramid fiber silk is quite important.
Summary of the invention
The purpose of the utility model is exactly the problem in the background technology, and a kind of loose sleeve layer strand type optical cable is provided.
For achieving the above object; The utility model adopts following technical scheme: the loose sleeve layer strand type optical cable, comprise optical fiber, sheath, loose sleeve pipe, center reinforcing prop and filling material, and the center is axially arranged with the center reinforcing prop in the sheath; Some loose sleeve pipes are distributed in reinforcing prop periphery in center in the sheath; The pine sleeve pipe is provided with some optical fiber, and filling material is filled in the gap of loose sleeve pipe and optical fiber respectively and the gap between loose sleeve pipe and the sheath, and said sheath comprises inner sheath, oversheath and the aramid fiber silk stiffener between inner sheath and oversheath; It is intracardiac that said center reinforcing prop is arranged in inner sheath, and loose sleeve pipe is positioned at inner sheath center reinforcing prop periphery.
The utility model is compared with background technology, have the intensity height, in light weight, the cross section is little, be convenient to characteristics such as erection construction.
Description of drawings
Fig. 1 is the schematic cross-section of loose sleeve layer strand type optical cable.
Embodiment
Embodiment 1: with reference to Fig. 1.The loose sleeve layer strand type optical cable; It comprises optical fiber 2, sheath 3, loose sleeve pipe 5, center reinforcing prop 1 and filling material 4; The center is axially arranged with center reinforcing prop 1 in the sheath 3, and some loose sleeve pipes 5 are distributed in reinforcing prop periphery in center in the sheath 3, and loose sleeve pipe 5 is provided with some optical fiber 2; Filling material 4 is filled in the gap of loose sleeve pipe 5 and optical fiber 2 respectively and the gap between loose sleeve pipe 5 and the sheath 3; Said sheath 3 comprises inner sheath 3c, oversheath 3b and the aramid fiber silk stiffener 3a between inner sheath 3c and oversheath 3b, and it is intracardiac that said center reinforcing prop 1 is arranged in inner sheath 3c, and loose sleeve pipe 5 is positioned at inner sheath 3c center reinforcing prop 1 periphery.
The loose sleeve layer strand type optical cable is set up on the power circuit more.In the high-voltage electric field environment, be in ADSS optical cable and the phase line around the high-voltage conducting wires, the electromotive force that capacitive coupling produced between the earth possibly produce electric current on the optical cable surface.When the optical cable surface moisture, possibly between dryin-up point and wet point electric arc take place, the heat of initiation can corrode oversheath and cause optical cable impaired.Research shows, when ADSS optical cable surface induction electromotive force during less than 12KV, can adopt the common PE protective cover material; If optical cable surface induction electromotive force during greater than 12KV, then must adopt anti-electric track resistant jacket material.The material that the sheath 3 of this product adopts is anti-electric track resistant jacket material.
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.
