Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of optical fiber composite overhead insulating cable is provided, fiber unit adopts aluminium tube type structure, conductor adopts the special-shaped single line of aluminium alloy stranded, conductor outer cladding layer structure, make it have lightweight, intensity is high, the mechanical electric performance advantage such as conduct electricity very well, and is applicable to electric power transfer and the optical-fibre communications of rated voltage 35KV and following distribution line.Technical scheme according to the utility model provides:
A kind of optical fiber composite overhead insulating cable, comprises the fiber unit being placed in cable center and the conductor be wrapped in outside fiber unit, and is wrapped in the layer structure outside conductor.
Further, described fiber unit comprises optical fiber, factice for filling and aluminum pipe; Factice for filling is located in aluminum pipe, and optical fiber to be located in aluminum pipe and to be immersed in factice for filling.
Further, described conductor comprises the annulus become by special-shaped single line concentric stranding, and the annulus number of plies is 1 ~ 5 layer.
Further, described special-shaped single line employing cross section is the aluminium alloy single line of " S " type, " Z " type or " watt " type.
Further, described conductor concentric stranding is on fiber unit.
Further, described layer structure comprises the conductor shield, insulating barrier and the insulation screen that are wrapped in successively outside conductor.
The utility model has the advantage of: adopt aluminium to make fiber unit protection tube, can improve the corrosion resistant performance of fiber unit, extend its useful life, aluminum pipe, also as conductor, reduces the outside diameter of cable, saves cable material.Aluminium alloy has higher intensity and good wire performance, makes conductor can improve the tensile strength of cable and reduce resistance with it, can avoid using steel wire to strengthen; Adopt special-shaped single line stranded, every layer of conductor all forms an annulus, plays good protection effect to protection fiber unit; Special-shaped single line is stranded, can also improve the activity coefficient of conductor, make its structure rounding, any surface finish; Aluminium, aluminium alloy are nonmagnetic substance, make conductor with it, can not produce eddy current, magnetic hysteresis loss in alternating current transmitting procedure.Coating conductor screen between conductor and insulating barrier, avoids between conductor and insulating barrier and partial discharge occurs, and improves the Electric Field Distribution of conductive surface; At insulating barrier outer cladding insulation screen, improve the Electric Field Distribution of surface of insulating layer, avoid insulating barrier partial discharge, cause cracking and branch aging.
