Abstract
The utility model discloses a photoelectric composite overhead insulated cable made of steel-cored aluminium stranded wire conductors. The photoelectric composite overhead insulated cable mainly comprises a steel core, hard-drawn aluminium wires and an optical unit, the steel core is externally wrapped by an aluminium layer, the steel core wrapped by the aluminium layer and the optical unit together with a plurality of hard-drawn aluminium wires are intertwisted together to form a cable body, the cable body is then filled with an inner shielding layer in the periphery to enable a cross section of the cable body to be circular, and the inner shielding layer is externally wrapped by an insulating layer. The photoelectric composite overhead insulated cable made of steel-cored aluminium stranded wire conductors has the advantages that the structural design is very reasonable, the tensile strength of conductors can be increased, the conductivity of the conductors can also be improved, the insulating layer adopts crosslinked polyethylene material of a relatively high temperature-resistant level, the long-term working temperature is 90 DEG C, the overall cost is relatively low, and gas released during combustion does no harm to the environment.
Description
Technical field
The utility model relates to the technical field of cable, more particularly relates to the technical field of photoelectric compound overhead insulating cable.
Background technology
Development along with urban and rural power grids are built, has brought infinite commercial opportunities to cable industry.At present common photoelectric compound overhead insulating cable, reasonable not due to what design in structure, and the material adopting is science very not also simultaneously, in current this important indicator of specified pull-off force, can not meet client's requirement.
Utility model content
The purpose of this utility model provides a kind of reasonable in design in order to solve above-mentioned deficiency exactly, the strong and steel reinforced aluminium conductor conductor photoelectric compound overhead insulating cable that conducts electricity very well of resistance to tension.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Steel reinforced aluminium conductor conductor photoelectric compound overhead insulating cable, it mainly includes steel core, hard-drawn aluminium wire and light unit, described steel core is coated with aluminium lamination, the steel core that is coated with aluminium lamination forms cable main with light unit together with many hard-drawn aluminium wire articulations together, at the peripheral internal shield of filling of cable main, make its cross section form circle again, described internal shield is coated with insulating barrier.
The described steel core that is coated with aluminium lamination is positioned at cable main middle position.
Described smooth unit adopts stainless steel cast.
Described hard-drawn aluminium wire forms by 15 to 22.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: structural design is very reasonable, and the structure that adopts aluminium Baogang core to be combined with aluminium lamination so both can increase the tensile strength of conductor, can improve again the conductance of conductor; Light unit adopts stainless steel cast, and the light unit of this structure provides the mechanical protection of further resistance to compression tension and manufactured optical fiber excess length for optical fiber, and the generation of excess fiber length makes optical cable have superior machinery, physical property; Insulating barrier adopts the higher cross-linking polyethylene materials of temperature resistant grade, and it can long-term work temperature be 90 ℃, and overall cost compare is low, the gas discharging while simultaneously burning to environment without any harm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
