Description
Technical field
The utility model relates to a kind of Optical Fiber composite overhead Ground Wire.
Background technology
Existing fiber composite overhead ground wire is generally made the outer stranded aluminium gold attribute (as aluminium alloy wire, aluminium-clad steel wire etc.) of the fiber unit making sleeve pipe with stainless steel tube, and stainless steel sleeve pipe and aluminum metal lines directly contact and can form potential difference.Composite overhead ground wire is in high aerial, easily attachment condensed state water, and can form electric current between the metal that steel is different with two kinds, aluminium, aluminium surface is destroyed, and aluminum metal lines is corroded, thus affects the useful life of Optical Fiber composite overhead Ground Wire.In addition, the aluminum metal lines that existing fiber composite overhead ground wire meets with its outsourcing when being struck by lightning easily is struck off, and causes ground wire impaired.
Summary of the invention
The utility model object is: provide a kind of corrosion-resistant type resistance to thunderbolt Optical Fiber composite overhead Ground Wire, it is aluminum pipe and adopt galvanized steel wire as outer twisted layer line in stainless steel tube outer cladding, the aluminum metal that effectively can solve overhead ground wire is easily corroded and easily by the problem of broken by lightning, improve overall corrosion resistance and withstand-lightning capability, extend the useful life of overhead ground wire.
The technical solution of the utility model is: the resistance to thunderbolt Optical Fiber composite overhead Ground Wire of a kind of corrosion-resistant type, comprise light unit and be stranded in the twisted layer line outside light unit, the aluminum pipe that described smooth unit comprises stainless steel tube, is arranged on the multifiber in stainless steel tube and is coated on outside stainless steel tube, described twisted layer line is galvanized steel wire.
Further, the diameter of described stainless steel tube is 3.6mm, and the diameter of described aluminum pipe is 7.1mm, and the quantity of described galvanized steel wire is 10, and the diameter of described galvanized steel wire is 3.09mm, and the optical fiber in described stainless steel tube is 24.
The utility model has the advantages that:
1, the utility model adopts galvanized steel wire as outer twisted layer line, galvanized steel wire can avoid the contact of steel substrate and any etchant solution, protection steel matrix is from corrosion, and in general atmosphere, zinc layers surface forms the very thin and closely knit zinc oxide film surface of one deck, it is difficult to water-soluble, therefore plays good protective effect to steel matrix, therefore has good corrosion resistance; In addition, suppose that same diameter is the monofilament of 3.0mm, the melt-out energy of galvanized steel wire is 184.6cal/cm, and the aluminium Baogang monofilament of 20%AS is 150.3cal/cm, aluminium alloy monofilament is then lower is 47.67cal/cm, and therefore, galvanized steel wire also has best resistance to thunderbolt.
2, smooth unit of the present utility model is at stainless steel tube outer cladding aluminum pipe, this smooth unit pull resistance, flexing resistance, air-tightness, water preventing ability are all better than common stainless steel pipe, if be struck by lightning, some electric current can pass through in aluminium lamination, short-circuit current capability with regard to making optical cable total adds 20% ~ 30%, thus improves the anti-lightning performance of optical cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
