Description
Technical field
The utility model is related to a kind of layer-stranding cables having stronger compressive property, belong to photoelectric communication transmission technology neck
Domain.
Background technology
With the fast development of optic communication 4G networks, the distribution of communications optical cable is more extensive and intensive, is faced
It lays environment and condition is also increasingly complex and changeable.Outdoor communication optical cable generally use is aerial, underground or a variety of layings such as underwater
Mode, in laid processes, be often required to stretch, winding, bending or squeeze, optical cable need to have preferable tension, resistance to compression and
The comprehensive performances such as bending performance.It wherein in order to enhance compressive property generally requires that metal armor layers are arranged in cable, but metal armour
The setting of dress layer not only reduces the lightning protection electrical property of optical cable, and is produced bigger effect to the flexibility and bending property of optical cable,
Also inconvenience is brought to the branch of optical cable.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of tool in view of the deficiency of the prior art
The layer-stranding cable of standby stronger compressive property, not only mechanical performance is excellent for the optical cable, pressure resistance, and flexible, is readily bent
With use, good environmental adaptability.
The utility model be solve the problems, such as it is set forth above used by technical solution be：Include layer-twisted type cable core and outer
Sheath, it is characterised in that water blocking layer, water blocking layer outer cladding inner sheath are provided with outside cable core, the inner sheath is foam polyolefin
Hydrocarbon inner sheath, inner sheath outer cladding oversheath.
By said program, the layer-twisted type cable core includes metalloid core reinforcer and is stranded in center reinforcemen periphery
Loose tube, optical fiber is set in Loose tube, the Loose tube is TPE Loose tubes.
By said program, the Loose tube is 6~12, and the fiber number in every Loose tube is 6~12 cores.
By said program, the foamed polyethylene inner sheath density of material is 0.3 ~ 0.7g/cm3, one-sided thickness is
1.0~2.5mm.
By said program, non-metal reinforced layer is installed between inner sheath and oversheath.
By said program, the metalloid core reinforcer is made of FRP or plastic sleeve FRP, it is described nonmetallic plus
Strong layer is made of aramid yarn or glass fiber yarn.
By said program, the water blocking layer is made of water blocking yarn or waterstop.
The utility model has the beneficial effect that：1. inner sheath uses foam polyolefin material, the foam polyolefin material of foaming
With higher rigidity and toughness, mechanical strength is good, and resistance to compression and shock resistance are strong, can when optical cable is by outer force effect,
Protection optical cable is not susceptible to deformation, increases the service life of optical cable, and foam polyolefin material has preferable flexibility, makes light
Cable has preferable bending property.2. polyolefine material is small to the permeability of vapor and air, water imbibition is low, with water blocking layer phase
Configuration can play better block-water effect.3. using thermoplastic elastomer (s)（TPE）Loose tube is made, optical cable is further improved
Flexibility and bending property.4. two layers of enhancement layer inside and outside center reinforcemen and non-metal reinforced layer is arranged, make optical cable have compared with
Strong tensile capacity can be used for laying compared with the processing of large span.5. the utility model be all-medium structure, outdoor laid have compared with
Strong lightning protection electrical property, and there is stronger environmental suitability.
