Abstract
The utility model discloses a kind of central tubular steel wire armoring cable, including sheath, the sheath section is circle, a circle composite band is provided with inside the sheath, a circle Loose tube is provided with inside the composite band, some armouring wire reinforcers are provided between the Loose tube and composite band, cable cream is filled between the Loose tube and composite band, optical fiber is provided with inside the Loose tube, fine cream is filled between the optical fiber and Loose tube, the beneficial effects of the utility model are：The tensile capacity of optical cable is enhanced, reduces the ability that each material expands with heat and contract with cold in optical cable, makes Loose tube be not easy to bounce back, it is therefore prevented that optic fibre force, substantially increases the ability to communicate of optical cable.
Description
Technical field
It the utility model is related to optical cable technology field, and in particular to a kind of central tubular steel wire armoring cable.
Background technology
The structure of existing central tube type optical cable is that center is a Loose tube, and both sides are provided with two parallel steel wires, it
Tensile capacity is poor, and optical cable is due to the change of ambient temperature during use, the performance of expanding with heat and contract with cold of each material in optical cable
Differ, it is also possible to cause Loose tube retraction, Loose tube inner fiber stress, so as to influence communication performance.
The content of the invention
In order to solve above-mentioned problem, the utility model provides a kind of central tubular steel wire armoring cable.
The utility model is to be achieved through the following technical solutions：A kind of central tubular steel wire armoring cable, including sheath, institute
Sheath section is stated as circle, a circle composite band is provided with inside the sheath, a circle Loose tube is provided with inside the composite band, it is described
Some armouring wire reinforcers are provided between Loose tube and composite band, cable cream, institute are filled between the Loose tube and composite band
State and be provided with optical fiber inside Loose tube, fine cream is filled between the optical fiber and Loose tube.
Preferably, the sheath is pe sheath.
Preferably, the sheath outer ring is provided with one layer of thermal insulation layer.
Preferably, the composite band is Copper-Aluminum compound band.
Preferably, one layer of fibre reinforced composites layer is provided with the sheath.
Compared with prior art, the beneficial effects of the utility model are：The tensile capacity of optical cable is enhanced, reduces light
The ability that each material expands with heat and contract with cold in cable, Loose tube is set to be not easy to bounce back, it is therefore prevented that optic fibre force, to substantially increase the communication of optical cable
Ability.
