Abstract

The utility model relates to a super corrosion-resistant type conducting wire which is characterized by comprising a steel core and a conductive layer, wherein the steel core is formed by twisting a galvanized steel wire into a steel stranded wire and also wrapping an aluminum layer outside the steel stranded wire or twisting an aluminum-clad steel wire into a stranded wire, the outside of the steel core is wrapped with a layer of or a plurality of layers of single wires of the conductive layer, the cross-sectional shapes of the single wires of the conductive layer are S or Z shapes, the twisting directions between the adjacent layers are opposite, and anti-corrosive grease is coated in gaps between the single wires of the conductive layer and the layers. The super corrosion-resistant type conducting wire has the advantage that the conducting wire has super resistance to chemical corrosion, electrochemical corrosion and crevice corrosion. The conducting wire is erected at a line and has the performance of super corrosion resistance, and the service life of the conducting wire can be greatly prolonged, so that a power transmission line is safer and more reliable during running.

Description

A kind of super corrosion resistant type lead
Technical field
The utility model belongs to the manufacturing and the application of used for transmission line lead, a kind of design of used for transmission line lead, technology of making and using of relating to.
Background technology
Electric power, is promptly held to receiving end from generating to the user from the power station, generally needs through very long road, and the conveying of electric power is finished by transmission line.Be set up in the lead on the transmission line, from the day of setting up, just be exposed in the environment that is set up, the state of corrosive environment, humidity and temperature around the circuit all will influence the extent of corrosion and the life-span of lead.The corrosion of lead can reduce following three kinds: i.e. chemical corrosion, electrochemical corrosion and crevice corrosion.Chemical corrosion be guide line in atmosphere with gas effects such as oxygen, chlorine, sulfur dioxide under the corrosion that takes place; Electrochemical corrosion has formed the corrosion of metal process after being meant the primary cell of being made up of two kinds of different metals and medium; Crevice corrosion is to exist the gap between the guide line single line, and corrosive environment in the atmosphere and rainwater etc. enter the corrosion that the inside of lead causes by the slit, and it still belongs to chemical corrosion and electrochemical corrosion in essence.Be set up in airborne lead, particularly be set up in the lead of coastal, island, industrial area, be easy to be corroded and shortened life-span of lead.In order to overcome above-mentioned shortcoming,,,, but make the mechanics degradation though can improve decay resistance can adopt aluminium alloy stranded conductor as the reinforcement load core of lead; If adopt aluminium-clad steel wire, but still can not improve the performance of crevice corrosion; When single line adopts the grease way, because of twisting with one heart, the circle line has big gap between single line, obviously increased wire weight behind the grease, unfavorable to the wire erection performance.
The utility model content
The purpose of this utility model provides a kind of super corrosion resistant type lead.
The technical solution adopted in the utility model is:
A kind of super corrosion resistant type lead, comprise steel core and conductive layer, described steel core is for to be twisted into steel strand wire and to be twisted into twisted wire at its outer wrap aluminium lamination or by aluminium-clad steel wire by galvanized steel wire, described steel core external packets is wrapped with one or more layers conductive layer single line, the shape of cross section of described conductive layer single line is S or Z-shaped, strand between adjacent layer scribbles anticorrosion grease on the contrary in the slit of described conductive layer single line and interlayer.
Is steel reinforced aluminium conductor as overhead transmission line with the lead of use amount maximum, because its existing aluminium has steel again, the structure of circle line concentric stranding had both existed chemistry, electrochemistry and crevice corrosion when therefore moving.Technical scheme of the present invention, be the steel core coated outside last layer aluminium in the lead, make between steel core that aluminium coats and conductor material aluminium and do not have potential difference, also promptly avoid producing the condition of electrochemical corrosion, next is the single line that the aluminum steel of conductor part is changed over molded lines by the circle line, the space significantly reduced after the molded lines strand was made in formed insufficient space of filling up into during like this by circle line strand system, for example the aluminium single line makes S into, Z-shaped, gap after being made by strand between single line is minimum, lead is from outer surface and nexine, S, the gap that the Z line forms is distortion again advances, even lead is soaked pouring down by rainwater like this, also because under the surface tension effects of rainwater, rainwater is difficult to accumulate on the line, also being difficult to enter the inside of lead, also is that the medium of the electrochemical corrosion of metal does not exist, and electrochemical corrosion just can not produce.At aluminium lamination single line and aluminium and aluminium Baogang interlayer, through above-mentioned technical finesse, gap between them is minimum, at this moment in this minimum gap, scribble the anticorrosion grease of one deck again, so also just reduce to the possibility of chemical corrosion minimum, this lead still can touch air, the rain and dew except the aluminium lamination of outermost, and remainder can not produce chemical corrosion, electrochemical corrosion and crevice corrosion, that is to say a kind of super corrosion-resistant lead.
The utility model has the advantages that: the lead of resistance to chemical attack, electrochemical corrosion and crevice corrosion, this wire erection have super decay resistance in circuit, useful life of extension lead greatly, safety and reliability when making the transmission line operation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Wherein: 1, galvanized strand wires, 2, aluminium lamination, 3, aluminum-cladding stranded wire, 4, the conductive layer single line, 5, anticorrosion grease.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of super corrosion resistant type lead of the present utility model, comprise steel core and conductive layer, steel core is to twist 1 synthetic steel twisted wire by galvanized steel wire, and twist 1 synthetic steel twisted wire external packets at galvanized steel wire and be wrapped with aluminium lamination 2, aluminium lamination 2 external packets are wrapped with multilayer conductive layer single line 4, scribble anticorrosion grease 5 in the slit of conductive layer single line 4 and interlayer, the shape of cross section of conductive layer single line 4 is S or Z-shaped, and the strand between adjacent layer is on the contrary.
