Abstract
The utility model relates to a novel layer-stranded-type optical cable. The optical cable is formed by a cable core and a sheath which wraps a periphery of the cable core. A plurality of optical fibers 1, a loose tube 3 which wraps the plurality of optical fibers and a water-resistance fiber paste 2 filled between optical fibers 1 and the loose tube 3 form a beam tube unit. The plurality of beam tube units and at least one filling rope 6 are intertwisted so as to form the cable core through a ''SZ mode'', wherein a steel wire reinforcement component 5 which is wrapped with a steel wire sheath 4 is taken as a center. A water-resistance cable paste 8 is filled in gaps among the beam tube unit, the filling rope 6 and the center reinforcement component. The cable core is successively wrapped with a double-surface plastic-coated corrugated steel belt 7 and a polyethylene outer sheath 9. According to the utility model, the steel wire 5 with a cushion layer 4 is taken as the center reinforcement component. On a basis that a tensile property is not influenced, an optical cable weight is reduced, production cost is reduced and simultaneously a construction difficulty is reduced too. The double-surface plastic-coated corrugated steel belt 7 is used so that a good mechanical property is provided for the optical cable.
Description
Technical field
The utility model relates to a kind of novel layer-stranding cable, belongs to the optical fiber cable field.
Background technology
Along with developing rapidly of telecommunications, optical cable is widely used in telecommunications, and wherein layer-stranding cable is to use the most a kind of optical cable.The general weight of existing layer-stranding cable is big, and cost is high, and difficulty of construction is big.
Summary of the invention
The purpose of the utility model is to provide a kind of weight lighter, the low layer-stranding cable that can guarantee mechanical property simultaneously of cost.
The solution of the utility model is: a kind of novel layer-stranding cable; Sheath by cable core is outer with being coated on cable core is formed; Cable core by the steel wire reinforcement that is in the cable core center, be set in the outer steel wire sheath of reinforcement, be arranged on sheath around mutually stranded many beam tube unit and at least one gasket for packing form; Gap between beam tube unit, gasket for packing and the central reinforce member is filled by the cable cream that blocks water; Described sheath is made up of two-sided plastic-coated embossing steel band that is wrapped in wrapping layer periphery and the pe sheath that is coated on the embossing steel band, described beam tube unit by multifiber, be coated on multifiber outward loose sleeve pipe and be filled in optical fiber and optical fiber and optical fiber and loose sleeve pipe between the fine cream that blocks water form.
Owing to adopt such scheme; The utility model has the advantages that: the utility model adopts the steel wire that has bed course as central reinforce member, on the basis that does not influence tensile property, has reduced the weight of optical cable like this; Reduced production cost, also reduced difficulty simultaneously for construction; The optical cable that is used for of two-sided plastic-coated embossing steel band provides the favorable mechanical performance.
Description of drawings
At Fig. 1 is the structural representation of the utility model, wherein: 1, optical fiber; 2, the fine cream that blocks water; 3, loose sleeve pipe; 4, steel wire sheath; 5, steel wire reinforcement; 6, gasket for packing; 7, two-sided plastic-coated embossing steel band; 8, the cable cream that blocks water; 9, tygon oversheath.
Embodiment
Below in conjunction with accompanying drawing the utility model is explained further details:
As shown in Figure 1; The utility model is made up of cable core and the sheath that is coated on its periphery; Multifiber 1, be coated on the outer loose sleeve pipe 3 of multifiber and be filled in optical fiber 1 with loose sleeve pipe 3 between the fine cream 2 that blocks water form the beam tube unit, many beam tube unit are that the stranded composition cable core of " SZ " mode is passed through at the center with at least one gasket for packing 6 with the steel wire reinforcement 5 that is coating steel wire sheath 4, the gap between beam tube unit, gasket for packing 6 and the central reinforce member is by cable cream 8 fillings that block water; Cable core coats two-sided plastic-coated embossing steel band 7 and tygon oversheath 9 outward successively; The utility model adopts the steel wire 5 that has bed course 4 as central reinforce member, on the basis that does not influence tensile property, has reduced the weight of optical cable like this; Reduced production cost, also reduced difficulty simultaneously for construction; The optical cable that is used for of two-sided plastic-coated embossing steel band 7 provides the favorable mechanical performance.
