Abstract
The utility model belongs to a corrosion-proof vibration-proof conductor for transmission lines. A seamless aluminum layer is coated between the outside of steel strands and aluminum strands for preventing the corrosion of etching gas to steel wires. On the ground that the distance less than 10 millimeters remains between the inner surface of the aluminum layer and the outer diameter of the steel strand at the same time, the aluminum layer and the steel strand mutually collide and absorb the energy for reducing the vibration of the conductor under the action of breeze. The conductor has the advantages of simple structure, corrosion resistance, and good vibration resistance.
Description
The utility model belongs to the corrosion-proof vibration-proof wire of used for transmission line.
The lead of used for transmission line generally adopts steel reinforced aluminium conductor, and the galvanized strand wires of this lead is a core, mainly plays the load effect, and aluminum steel plays electric action on its outside strand.This lead can destroy because of the vibration of corroding and gentle breeze causes in long-term the use, therefore need take measures, to improve the anti-corrosion and vibrationproof performance of lead.
Prior art adopts following method to improve the corrosion resistance and the vibrationproof of lead usually.
Between steel core wire and aluminium stranded conductor, coat the anticorrosion grease of making by the machine material, stop the corrosion of rain and dew and corrosive gas, prolong the steel wire life-span steel wire.Make it to be complementary with the aluminum steel life-span, but anticorrosion grease has increased the weight of lead, long-term use can be worn out and be lost efficacy, and this lead joint when carrying out joint need be cleaned except that degrease and increased trouble.Other method is to replace galvanized steel wire with aluminium-clad steel wire, makes that load in the lead is identical with conduction two parts contacted metal can not to be formed primary cell and do not corrode.Though more than two kinds of methods can improve the corrosion resistance of lead, can not improve vibrationproof simultaneously.
Be to improve vibrationproof, the measure of taking is to hang stockbridge damper on lead, protect lines, but hangs additional hanger, makes circuit increase the complexity of deadweight and installation, maintenance.The other method that improves vibrationproof is the structure that changes conductive layer, plays antihunt action as making self damping conductor with arch form aluminum steel composition conductive layer.These two kinds of methods can only vibrationproof and can not be anti-corrosion.
The purpose of this utility model provides a kind of not only had corrosion resistance but also corrosion-proof vibration-proof wire that can vibrationproof.
For finishing the proposed invention purpose, adopted following technical scheme:
At the steel strand wire that are in the lead core with twist cladding one free from flaw and the smooth aluminium lamination of surfaces externally and internally between the aluminium stranded conductor of steel strand wire outsides, the distance between the inner surface of this aluminium lamination and the steel strand wire external diameter should promptly constitute corrosion-proof vibration-proof wire less than 10 millimeters.
The shake steel strand wire of lead of this corrosion-proof vibration-proof can be galvanized steel wires, also can be the plate golding aluminium zinc alloy steel wires, can also be the steel wires that does not plate any material.These steel wires that coating arranged or do not have coating can be general steel wires commonly used, also can be the steel wires of underrelaxation.
Free from flaw aluminium lamination and aluminium stranded conductor can be metallic aluminiums, also can be aluminium alloys.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the sectional view of corrosion-proof vibration-proof wire.
Among the figure, the steel strand wire 1 that are twisted into steel wire are formed the load part of lead, push or weld all smooth aluminium lamination 2 of a fissureless surfaces externally and internally in its outside, distance 3 between the external diameter of the inner surface of aluminium lamination 2 and steel strand wire 1 should be twisted the current-carrying part of aluminum steel 3 as lead then again less than 10 millimeters in the outside of aluminium lamination.The lead that constitutes by above three parts be can be anti-corrosion again can vibrationproof lead.
Because a free from flaw aluminium lamination or aluminium alloy layer 2 are arranged between steel strand wire 1 and aluminium stranded conductor 3, thereby can stop rain and dew or etchant gas to the corrosion of steel strand wire 1 and play the effect of corrosion protection, again owing to have one less than 10 mm distance between the inner surface of aluminium lamination 2 and the steel strand wire 1, make aluminium lamination 2 and steel strand wire 1 become relatively independent two parts, quality between them is all different with natural frequency, steel strand wire 1 absorb energy with aluminium lamination 2 because of colliding mutually under the effect of gentle breeze, thereby can play antihunt action.
This lead with free from flaw aluminium lamination, have simple in structure, can be anti-corrosion again can vibrationproof advantage.
Claims (4)
1, a kind of by the steel strand wire that are in the lead core with twist the corrosion-proof vibration-proof wire that the aluminium stranded conductor outside steel strand wire is formed, it is characterized in that steel strand wire 1 and twist the aluminium lamination 2 that cladding between the aluminium stranded conductor 3 outside steel strand wire 1 one is seamless and surfaces externally and internally is smooth, the distance, delta between the inner surface of aluminium lamination 2 and steel strand wire 1 external diameter should be less than 10 millimeters.
