Abstract
The invention discloses a medium-voltage soft-conductor photoelectric integrated cable comprising a plurality of power units. The power units are covered with a water stop layer, a liner layer, a wire armored layer and an outer sheath layer in order. A plurality of fiber units are disposed in gaps among the power units. Each power unit comprises a soft-conductor wire core which is covered with an inner shield layer, an insulating layer and an outer shield layer in order. Each fiber unit comprises a loose tube accommodating a fiber core, fiber paste and a reinforcing wire, and the loose tube of the fiber unit is covered with an asbestos cloth layer and a silicone layer in order. When the medium-voltage soft-conductor photoelectric integrated cable operates at high temperature for a long time, the interior temperature of the cable can be lower than 60 DEG C, and the transmission performance of the cable is unaffected; in addition, the asbestos cloth and silicone wrapping the fiber units also has the function of enhancing fiber outer support, and the fiber units are protected from crush when the fiber units and the power units are stranded into the cable.
Description
Technical field
The present invention relates to a kind of middle pressure flexible conductor optoelectrical cable.
Background technology
Optoelectrical cable is that light harvesting is fine, power transmission cable is in the composite rope of one, and can realize optical fiber communication simultaneously again can transferring electric power, can avoid the problem of secondary wiring in construction.Optical cable is different to the requirement of operational environment with power cable, for example important operational environment index is ambient temperature and ambient humidity, the environment for use temperature of optical cable is generally 60 ℃ of left and right, and the normal working temperature of power cable is between 40 ℃-90 ℃, optical cable has tighter restriction to humidity, therefore optical cable and power cable simple superposition can not be used in combination.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly can meets the middle pressure flexible conductor optoelectrical cable that optical cable and power cable require environment for use simultaneously.
For solving the problems of the technologies described above, in the present invention, press flexible conductor optoelectrical cable, comprise a plurality of power units, a plurality of power units are sequentially coated with water blocking tape layer outward, inner covering, wire armoring layer and external sheath layer, the place, gap forming between described a plurality of power unit is provided with a plurality of fiber units, described each power unit has flexible conductor core, flexible conductor core is sequentially coated with internal shield outward, insulating barrier and outer shielding layer, described each fiber unit has loose sleeve pipe, in pine sleeve pipe, there is fibre core, fine cream and reinforcement steel wire, the loose sleeve pipe of described each fiber unit is also sequentially coated with asbestos layer of cloth and layer of silica gel outward.
The external sheath layer of each described power unit is also sequentially coated with shielding layer of copper wires and the anti-copper strips layer of pricking outward.
Place, gap between described a plurality of power unit and a plurality of fiber unit is filled with waterproof paste, is also provided with plastic-aluminum combined belt between described water blocking tape layer and inner covering.
Adopt the middle pressure flexible conductor optoelectrical cable of said structure, because the loose sleeve pipe of described each fiber unit is also sequentially coated with asbestos layer of cloth and layer of silica gel outward, therefore can guarantee that the temperature of optical cable inside when optoelectrical cable moves under long term high temperature state is below 60 ℃, can not affect the transmission performance of optical cable, asbestos cloth and silica gel are wrapped in outside fiber unit and can also play and strengthen outer fiber supporting role in addition, while making fiber unit and power unit twisted synthesizing cable, fiber unit is not crushed damage.Because the external sheath layer of each described power unit is also sequentially coated with shielding layer of copper wires and the anti-copper strips layer of pricking outward, power unit is played to better signal shielding effect, make power unit and fiber unit can not produce signal and disturb; Because the place, gap between described a plurality of power units and a plurality of fiber unit is filled with waterproof paste; between described water blocking tape layer and inner covering, be also provided with plastic-aluminum combined belt; adopt such structure can play good block-water effect, power unit and fiber unit are had to better protection effect.
