Abstract
The utility model discloses a layer-stranding cable with a 1+4 structure. The layer-stranding cable with the 1+4 structure includes a cable core and a plastic sheath wrapped outside the cable core. A protection layer is arranged between the cable core and the plastic protection sheath. The cable core includes a reinforcing piece disposed in the center, four PBT sleeve pipes twisted on the outer periphery of the reinforcing piece and four GFRP (Glass Fiber Reinforcing Plastic) fiber rods arranged in gaps between the PBT sleeve pipes and the protection layer, wherein the reinforcing piece, the PBT sleeve pipes and the GFRP fiber rods are arranged successively from inside out. Fiber paste is filled between the PBT sleeve pipes and an optical fiber. Waterproof cable paste is filled between eh PBT sleeve pipes and the protection layer. According to the utility model, the cable core adopts the 1+4 structure formed by the reinforcing piece and the four PBT sleeve pipes and a plastic filling rope is removed. Compared with an optical cable with a 1+5 structure, the layer-stranding cable with the 1+4 structure is reduced in outer diameter, low in weight and low in production cost and is very suitable for cable arrangement in occasions that urban outdoor underground communication pipelines are crowded. Beside, by using the four GFRP fiber rods, the tensile strength of the layer-stranding cable with the 1+4 structure is improved.
Description
Technical field
The utility model relates to the optical cable field, particularly relates 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.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model 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 utility model 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 optimal technical scheme of the present utility model, number of fibers is 2 ~ 6 in described each PBT sleeve pipe.
As optimal technical scheme of the present utility model, described reinforcement is the phosphatization steel wire, and diameter is 0.9mm.
As optimal technical scheme of the present utility model, described protective seam is made up of aluminium strip, waterstop or steel band, waterstop.
As optimal technical scheme of the present utility model, described plastic sheath is that medium density polyethylene is made.
