Abstract
The utility model discloses a communication cable, including the fire -retardant sheath of PVC, the parcel has the medium density polyethylene layer in the fire -retardant sheath of PVC, medium density polyethylene in situ parcel has the steel band, be equipped with the cable core in the steel band, the cable core comprises block water cable core and optic fibre, the optic fibre overcoat has PBT pine pipe box, the optic fibre intussuseption is filled with fine cream. The utility model discloses it is rational in infrastructure, the long service life of cable, signal transmission is stable.
Description
Technical field
The utility model relates to a kind of telecommunication cable.
Background technology
At present, often need in the field of communications with twisted-pair feeder transmitting the various signal of telecommunication, traditional telecommunication cable is formed primarily of insulated wire cores and sheath, copper core all adopts TR type copper cash, communication cable is used in each intelligent building, comprehensive wiring market, be in great demand, and copper resource scarcity at present, copper valency goes up swift and violent, the consumption of copper material accounts for the major part of whole telecommunication cable cost, huge cost pressure is brought, the defects such as cable of the prior art exists unreasonable structure, and useful life is short to telecom cable production.
Utility model content
The utility model object there is provided a kind of rational in infrastructure, the long service life of cable, the telecommunication cable of stable signal transmission.
The utility model technical solution problem provides following scheme:
A kind of telecommunication cable, comprise PVC fire retardant jacket, it is characterized in that: in described PVC fire retardant jacket, be enclosed with medium density polyethylene layer, steel band is enclosed with in described medium density polyethylene layer, cable core is provided with in described steel band, described cable core is made up of block water cable core and optical fiber, and described optical fiber outer jacket has PBT pine pipe box, is filled with fine cream in described optical fiber.
Be provided with gasket for packing in described steel band, the side of described gasket for packing is provided with steel wire.
The utility model adopts and be provided with medium density polyethylene layer in PVC flame-retardant layer; improve the uvioresistant of cable and oxidation resistant effect; and PBT pine pipe box layer is provided with in the outside of optical fiber; because optical fiber is the filament pulled into by quartz; because of its very fragile, frangibility; so loose tube layer is for the protection of the effect of optical fiber, and in cable core, be filled with steel wire and gasket for packing, effectively strengthen the intensity of optical cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See accompanying drawing, a kind of telecommunication cable, comprise PVC fire retardant jacket 1, in described PVC fire retardant jacket 1, be enclosed with medium density polyethylene layer 2, in described medium density polyethylene layer 2, be enclosed with steel band 3, cable core is provided with in described steel band 3, described cable core is made up of block water cable core 4 and optical fiber 5, and described optical fiber 5 overcoat has PBT pine pipe box 6, is filled with fine cream 7 in described light 5 fibre, be provided with gasket for packing 8 in described steel band 3, the side of described gasket for packing 8 is provided with steel wire 9.
