Abstract
The invention discloses a layer-stranding optical cable with a 1+4 structure. The layer-stranding optical cable comprises a cable core and a plastic sheath wrapped outside the cable core, wherein a protecting layer is arranged between the cable core and the plastic sheath. The cable core comprises a reinforcing component, four PBT (Polybutylece Terephthalate) sleeve pipes and four GFRP (Glass Fiber Reinforced Plastic) fiber rods from inside to outside, wherein the reinforcing component is positioned at the center position; the four PBT sleeve pipes are hinged at the periphery of the reinforcing component; the four GFRP fiber rods are arranged in a gap formed between the PBT sleeve pipes and the protecting layer; fiber paste is filled between the PBT sleeve pipes and fibers; and water-resistant cable paste is filled between the PBT sleeve pipes and the protecting layer. Based on the 1+4 structure formed by one reinforcing component and four PBT sleeve pipes, one plastic filling rope is saved, so that compared with the cable with the 1+5 structure, the layer-stranding optical cable with the 1+4 structure is less in cable diameter and lighter in weight, and thus the production cost is saved, and the layer-stranding optical cable is very suitable for the optical stable routing for the crowded places of outdoor underground communication pipelines of a city. In addition, by utilizing the four GFRP fiber rods, the tensile strength of the optical cable is improved.
Description
Technical field
The present invention relates to the optical cable field, particularly relate to a kind of layer-stranding cable of 1+4 structure.
Background technology
The layer-stranding cable of existing outdoor application generally adopts the 1+5 structure, as shown in Figure 1, namely cable core is made up of a reinforcement steel wire 11, five loose sleeve pipe (PBT sleeve pipe) 13 and plastics gasket for packings 14 that are enclosed with several optical fiber 12 of layer strand around reinforcement steel wire 11 at center.When optical fiber 12 core numbers in the optical cable during less than 24 cores, actual fiber pine sleeve pipe 13 is no more than 4, like this, in order to keep the relative rounding of cable core, has also used a plastics gasket for packing 14, has constituted the cable core of 1+5 structure.Such structure had both increased uses the cost of plastics gasket for packing, and makes the diameter (9.3mm) bigger than normal of cable core and whole optical cable, has also caused the materials of other materials such as plastic sheath to increase, and has improved production cost of products.In addition, the optical cable tensile strength of this 1+5 structure is also low.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide that a kind of external diameter is little, quality is light, production cost is low, tensile strength is high and be highly suitable for the layer-stranding cable of 1+4 structure of the cloth cable optical cable of the crowded occasion of the outdoor underground communication pipeline in city.
For realizing above-mentioned technical purpose; reach above-mentioned technique effect; the present invention is achieved through the following technical solutions: a kind of layer-stranding cable of 1+4 structure; comprise cable core and be wrapped in the outer plastic sheath of cable core; be provided with protective seam between described cable core and the plastic sheath; described cable core is followed successively by a reinforcements that is positioned at the centre from the inside to the outside; stranded four of being arranged on the reinforcement periphery are enclosed with the PBT sleeve pipe of several optical fiber and are arranged at four glass fiber reinforced plastics GFRP fiber rods in gap between described PBT sleeve pipe and the protective seam; be filled with fine cream between described PBT sleeve pipe and the optical fiber, be filled with the cable cream that blocks water between described PBT sleeve pipe and the protective seam.
As the preferred technical solution of the present invention, number of fibers is 2 ~ 6 in described each PBT sleeve pipe.
As the preferred technical solution of the present invention, described reinforcement is the phosphatization steel wire, and diameter is 0.9mm.
As the preferred technical solution of the present invention, described protective seam is made up of aluminium strip, waterstop or steel band, waterstop.
As the preferred technical solution of the present invention, described plastic sheath is that medium density polyethylene is made.
As the preferred technical solution of the present invention, the external diameter of described PBT sleeve pipe is 1.8mm.
As the preferred technical solution of the present invention, the wall thickness of described PBT sleeve pipe is 0.35mm.
As the preferred technical solution of the present invention, the diameter of described glass fiber reinforced plastics GFRP fiber rod is 0.7mm.
The invention has the beneficial effects as follows: cable core of the present invention has adopted the 1+4 structure of a reinforcements and four PBT sleeve pipes, saved a plastics gasket for packing, than the layer-stranding cable that has now with the 1+5 structure of core number, cable outer diameter is little by about 20%, in light weight about 25%, both save production cost, be highly suitable for the cloth cable optical cable of the crowded occasion of the outdoor underground communication pipeline in city again.And the gap between PBT sleeve pipe and protective seam also is provided with four glass fiber reinforced plastics GFRP fiber rods, has improved the tensile strength of optical cable.
