Abstract
Provided is a stranded steel wire armored optical cable. The optical cable comprises a plurality of loose sleeves, each of which is internally provided with a plurality of light guide fibers and water blocking yarns. The loose sleeves and a reinforced steel wire constitute a cable core which is sequentially coated with a longitudinally-wrapped water blocking tape, a polyethylene inner sheath, a steel wire armored layer and a polyethylene outer sheath. The longitudinally-wrapped water blocking tape and the water blocking yarns quickly swell when exposed to water so as to achieve a water blocking effect. The reinforced steel wire and the steel wire armored layer improve tensile strength and anti-electromagnetic interference performance of the optical cable to enable the optical cable to withstand a relatively large installation gap.
Description
Technical field
The present invention relates to a kind of optical cable, particularly there is the optical cable of the layer-twisted type structure of tension, water resistance.
Background technology
At present, optical cable is mainly to adopt optical fiber and the sheath outside cable core in loose sleeve pipe, loose sleeve pipe to form, and for anti-sealing and moisture enter optical cable, affects Optical Fiber Transmission effect, in loose sleeve pipe, place the fine cream that blocks water, outside cable core and cable core gap location fill the cable cream that blocks water, thus traditional optical cable in use, the clean expensive time of ointment, ointment pollutes the environment, can affect optical fiber quality, also can be subject to installing the restriction of drop, how restricted use occasion is also simultaneously.
Summary of the invention
In order to overcome the ointment contaminated environment in existing optical cable, affect the deficiency of fiber optic cable communications quality, the invention provides a kind of layer-twisted type steel wire armoring cable, it can not cause secondary pollution, has tension, water resistance, the high communication quality.
The technical solution adopted for the present invention to solve the technical problems is, layer-twisted type steel wire armoring cable comprises a plurality of loose sleeve pipes, in each loose sleeve pipe, be provided with many light transmitting fibers and water blocking yarn, pine sleeve pipe and reinforcement steel wire form cable core, cable core is outward vertical bag waterstop, vertical bag waterstop is outward tygon inner sheath, and tygon inner sheath is outward wire armoring layer, and wire armoring layer is outward outer protective polyethylene cover.
The invention has the beneficial effects as follows, vertical bag waterstop and water blocking yarn are met water and are expanded rapidly, reach block-water effect; Strengthen tension and anti-electromagnetic interference performance that steel wire and wire armoring layer improve optical cable, make optical cable can bear larger installation drop.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. light transmitting fibers in figure, 2. water blocking yarn, 3. loose sleeve pipe, 4. reinforcement steel wire, 5. vertical bag waterstop, 6. tygon inner sheath, 7. wire armoring layer, 8. outer protective polyethylene cover.
Embodiment
In Fig. 1, layer-twisted type steel wire armoring cable comprises four loose sleeve pipes 3, in each loose sleeve pipe 3, be provided with many light transmitting fibers 1 and water blocking yarn 2, pine sleeve pipe 3 and reinforcement steel wire 4 form cable cores, cable core is outward vertical bag waterstop 5, vertical bag waterstop 5 is outer is tygon inner sheath 6, and tygon inner sheath 6 is outer is wire armoring layer 7, and wire armoring layer 7 is outer is outer protective polyethylene cover 8.
