Technical field
The utility model relate to a kind of be applicable to long-distance transmission line there is Remote feeding function OPGW.
Background technology
The construction of long distance transmission line, need to set up relay station every about 350 kilometers in power circuit, the construction cost of relay station is high, even in remote mountain areas or ruthless area because being difficult to build relay station, and abandon the erection plan of power circuit.
If in power circuit, there are one or two ground wires to have the function of Remote feeding, just without the need to building relay station, directly on electric force pole tower, trunking are installed.But also there is no similar ground wire or OPGW product both at home and abroad.
Summary of the invention
The purpose of this utility model provides one to have Remote feeding function OPGW for above-mentioned weak point, that one is applicable to Optical Fiber composite overhead Ground Wire in long distance, jumbo power circuit, for the area of electric power relay station cannot be set up, provide the solution that power circuit construction is new, solve the problem that remote districts power supply is difficult.
The utility model takes following technical scheme to realize:
One has Remote feeding function OPGW, it comprises center aluminium-clad steel wire, fiber unit, some power supply conductor monofilament, unlined aluminium steel clad wire and outer aluminium-clad steel wires, described fiber unit, power supply conductor monofilament and unlined aluminium steel clad wire are evenly stranded in center aluminium-clad steel wire and form second layer structure outward, described outer aluminium-clad steel wire is stranded in outside second layer structure, between described fiber unit and power supply conductor monofilament and all spaced apart by unlined aluminium steel clad wire between power supply conductor monofilament and power supply conductor monofilament.
Further, described fiber unit comprises stainless steel tube I, is provided with 1 ~ 4 core multimode fiber and some monomode fibers, is filled with fiber filling gel between multimode fiber and monomode fiber in described stainless steel tube I.Multimode fiber is used for temperature survey, and monomode fiber is used for communication.
Further, described power supply conductor monofilament is made up of stainless steel tube II, insulating barrier, enamel insulated wire, at outer wrapped or extrusion molding one layer insulating of enamel insulated wire, at insulating barrier vertical bag one deck stainless steel tube II outward, makes power supply conductor monofilament.
Further, the THICKNESS CONTROL of described insulating barrier at 0.1 ~ 1mm, to strengthen the class of insulation of enamel insulated wire; The THICKNESS CONTROL of described stainless steel tube II at 0.1 ~ 0.25mm, with protect conductor and insulating barrier injury-free under the factors such as construction, external force, Long-Time Service and moisture attacks.
The utility model is applied to long distance transmission line, ruthless area, has the following advantages:
