The optical fiber is characterized in that the center of the skeleton is provided with a nonmetal central reinforcing part in a passing-through manner; the periphery of the skeleton is sequentially wrapped by a waterproof part and a nonmetal reinforcing part; and the outermost layer is wrapped by the external sheath. The beneficial effects of the invention are that 1, the optical cable employs a skeleton-type optical cable structure, and the interior and exterior of the skeleton are provided with the nonmetal reinforcing parts, thereby enabling the optical cable to be high in strength, good in tensile property, and large in span; 2, the fiber filling density is high, and the relative diameter of the optical fiber is small; 3, the optical cable is easy for the setting of a separating window, and optical fibers can be separated and extracted from the separating window; the construction and connection are convenient, and a full-dry structure is more convenient for construction, connection and maintenance; 4, an all-dielectric structure can be used in a power transmission line, is resistant to lightning stroke, cannot be affected by electromagnetic interference, can be laid in a live-line manner, facilitates the separating and winding of the optical fibers, is high in laying success rate, and is low in cable consumption.
Description
Technical field
The present invention relates to optical communication field, be specifically related to the nonmetal self-supporting slotted core cable of a kind of dry type.
Background technology
At present, in power circuit, the aerial optical cable be laid on ultra-high-tension power transmission line mainly All Dielectric self-support, i.e. ADSS(All Dielectric Self-supporting) optical cable, this type of optical cable is generally layer-twisted type cable core structure, and in containing the sleeve pipe of optical fiber filling greasy for preventing water, this optical cable not only structure is comparatively complicated, optical fiber plot ratio is less, self-strength is low, manufacturing cost is high, and have the existence of ointment due to cable core, must first clear up ointment and clean when construction continues, continue to construction and bring inconvenience, too increase difficulty of construction and cost.
Along with the propelling of 4G networking, backbone network turns to the construction demand of Metropolitan Area Network (MAN) and Access Network day by day to promote, fiber to the home is day by day universal, and in fiber to the home engineering, fiber cable laying is very important link, need to start separator window during difference optical fiber house lead in, separator window is started for common layer strand aerial optical cable and will reduce its tensile strength, cause the loss of optical fiber, in addition, due to factice for filling in cable, can continue to construction and make troubles and cause environmental pollution.
Summary of the invention
Technical matters to be solved by this invention is that the deficiency existed for above-mentioned prior art provides a kind of dry type nonmetal self-supporting slotted core cable, and not only intensity is high for it, and tensile property is good, and is easy to offer separator window, and construction continues conveniently.
The technical scheme that the problem that the present invention is the above-mentioned proposition of solution adopts is: comprise oversheath and skeleton, longitudinally fine groove is offered at the circumference interval, periphery of skeleton, longitudinally be installed on optical communication element in fine groove, it is characterized in that described frame center is coated with metalloid core reinforcement, coated water-blocking component and non-metal reinforcement member successively in skeleton periphery, the coated oversheath of outermost layer.
By such scheme, be coated with inner sheath at water-blocking component, non-metal reinforcement member is arranged between inner sheath and oversheath.
By such scheme, described metalloid core reinforcement is fibre-reinforced plastics FRP, glass reinforced thermoset plastics GRP or fibre reinforced composites KFRP, and described metalloid core reinforcement is bonding with skeleton integral.
By such scheme, described optical communication element is one or more in optical fiber, fibre bundle, fibre ribbon, tight tube fiber.
By such scheme, the fine groove of described longitudinal direction be C type, U-shaped in one or both.
By such scheme, the fine groove of described longitudinal direction helically twists or SZ strand.
By such scheme, described water-blocking component is waterstop and/or water blocking yarn, wrapped in skeleton periphery.
By such scheme, described non-metal reinforcement member is high strength aramid yarn or glass fibre.
By such scheme, described oversheath is uv-resistant macromolecular material or resistance to electric trace macromolecular material oversheath.
Beneficial effect of the present invention is: 1, adopt slotted core cable structure, inside and outside skeleton, configure non-metal reinforcement member, make cable strength high, tensile property is good, and it is large that span maked somebody a mere figurehead by optical cable; 2, optical fiber filling density is high, and optical cable relative diameter is little; 3, be easy to offer separator window and extracted out from separator window difference by optical fiber, construction continues conveniently, and the construction of being more convenient for of dry type structure continues and safeguards in addition; 4, all dielectric structure can use at transmission line of electricity, anti-lightning, not by electromagnetic interference (EMI), can not power-off lay, and is convenient to optical fiber branching and dish stays, and it is high to lay success ratio, and cable consumption is few.
Accompanying drawing explanation
Fig. 1 is the radial section figure of one embodiment of the invention.
Fig. 2 is the radial section figure of another embodiment of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
First embodiment as shown in Figure 1, comprise oversheath 6 and skeleton 2, be made up of high density polyethylene, and lateral pressure resistant performance is good, has good protective effect to optical communication element by skeleton, do not damage optical fiber when can realize stripping fiber optic cables simultaneously, improves the convenience that continues; 3 ~ 12 fine grooves of longitudinal direction are offered at the circumference interval, periphery of skeleton, longitudinally fine groove lateral cross section is U-shaped, and longitudinally fine groove helically twists or SZ strand, longitudinally loads in fine groove and is installed on optical communication element 5, described optical communication element is optical fiber or fibre ribbon, and fibre ribbon can be 4 cores, 6 cores, 8 cores or 12 core ribbon; Described frame center is coated with metalloid core reinforcement 1, and metalloid core reinforcement is fibre-reinforced plastics FRP, and described metalloid core reinforcement is bonding with skeleton integral.Water-blocking component 3 is surrounded with in skeleton periphery, water-blocking component is waterstop containing water-proofing powder or water blocking yarn, at waterstop outer cladding non-metal reinforcement member 4, described non-metal reinforcement member is high strength aramid yarn, or be glass fibre, the coated oversheath of outermost layer, oversheath is uv-resistant macromolecular material oversheath.
