Abstract
A layer-twisting ADSS optical cable relates to an optical cable for power communication. The optical cable comprises a cable core and a sheath, wherein the sheath wraps up the cable core, the cable core comprises a reinforcing core and a fiber unit, the reinforcing core is positioned in the central section of the cable core, and the fiber unit is arranged in a loose sleeve which is vertically twisted outside the reinforcing core. The optical cable is characterized in that the sheath comprises a reinforcing layer and an outer protection layer, wherein the outer protection layer wraps up the reinforcing layer, the reinforcing layer wraps up the cable core, a water resisting band is laid between the cable core and the reinforcing layer, and a bird damage-preventing protective layer is arranged outside the outer protection layer. The bird damage-preventing protective layer is formed by longitudinal wrapping or winding of reinforced fiber bands. A polyethylene external sheath is laid outside the bird damage-preventing protective layer, protrusions are arranged on the outer wall of the reinforcing layer, and position clip structures matching with the protrusions are arranged on the inner wall of the outer protection layer. Slipping between layers of the sheath can be prevented, and bird damage can be prevented. The layer-twisting ADSS optical cable is light and has high practical and promotion value.
Description
Technical field
The present invention relates to a kind of layer stranded ADSS fiber optic cable, relate to a kind of power communication optical cable, particularly relate to a kind of power communication ADSS optical cable.
Background technology
At present, the electric power communication optical cable used by power communication system is ADSS optical cable, and this kind of optical cable is the second largest electric power communication optical cable after OPGW optical cable, is extensively erected at along the shaft tower of electric power transmission line.But owing to ADSS optical cable is a kind of all dielectric electric power communication optical cable (that is: without any metal material), there is problems with:
1, frequently suffer from the unfirmly closing of the large birds, unfirmly closing and rodent the damage of ADSS optical cable is happened occasionally, serious threat power communication system properly functioning.Although various places take a series of as increased the measures such as protection device at ADSS optical cable outer surface to stop the infringement to ADSS optical cable of unfirmly closing and rodent after ADSS optical cable installation; but protection device can be only installed at two sides of shaft tower; can not install along the line; site operation is difficult to, and unfirmly closing and rodent are the best to the infringement protected effect of ADSS optical cable；
2, existing ADSS optical cable is generally made up of cable core and the multi-protective layer that is wrapped in cable core peripheral; often there is slip phenomenon between layers owing to material is different in each protective layer; affect the reliability of ADSS optical cable transmission information; and reduce the use time of ADSS optical cable, virtually increase electrical network and lay cost；In place of this is the deficiencies in the prior art；
3, existing ADSS generally uses ointment to fill, and optical cable quality lays particular stress on, and lays inconvenience, easily pollutes fiber junctions when optical cable baring continues.
Summary of the invention
In order to solve problem above, the invention provides a kind of layer stranded ADSS fiber optic cable, this optical cable, it can be avoided that slip between sheath every layer, prevents birds, and lighter weight.
Technical scheme is as follows: a kind of layer stranded ADSS fiber optic cable, including cable core and sheath, described sheath cladding cable core, described cable core includes strengthening core and fiber unit, described strengthening core is positioned at the middle part of cable core, described fiber unit is arranged in Loose tube, described Loose tube is longitudinally twisted outside strengthening core, described sheath includes enhancement Layer and outer jacket, described outer jacket cladding enhancement Layer, described enhancement Layer parcel cable core, it is laid with waterstop between described cable core and enhancement Layer, described outer jacket is outside equipped with anti-unfirmly closing protective layer, described anti-unfirmly closing protective layer is by the vertical bag of reinforcing fiber band or wrapped forms, described anti-unfirmly closing protective layer outer layer is laid with outer layer of polyethene sheath, it is provided with lobe on described enhancement Layer outer wall, the retaining structure matched with lobe it is provided with on the inwall of described outer jacket.
Technical solution of the present invention also includes: described enhancement Layer includes glass layer and basalt fibre band, described basalt fibre cladding glass layer, described glass layer cladding waterstop.Use basalt fibre band and high strength glass fiber Application of composite, instead of traditional aramid fiber, both can reduce the price of ADSS optical cable, developed countries can be broken again to the technology of aramid fiber and commercial monopoly；Basalt fibre band is anorganolite stone material matter because of it, and chemical stability is good, and can arc resistant and because of arc discharge produce heat, it is possible to provide arc resistant performance.
Technical solution of the present invention also includes: is laid with water blocking yarn outside described Loose tube, is filled with absorbent material in described Loose tube, preferably moistureproof, it is to avoid to occur unexpectedly.
Technical solution of the present invention also includes: the absorbent material filled in described Loose tube is water-proofing powder.
