Description

A kind of energy-saving conductor used under heavily contaminated environment

Technical field

The energy-saving conductor that the utility model relates to use under a kind of heavily contaminated environment.

Background technique

The conducting wire used under China's heavily contaminated environment at present, structure and anti-corrosive properties are essentially all using round wires structure, line A kind of anti-corrosion type grease is coated between core and internal layer aluminium layer；Another structural outside layers uses molded line structure, core and unlined aluminium A kind of anti-corrosion type grease is coated between layer.Core uses regular tenacity steel wire or the lower aluminum-clad steel wire of intensity, and aluminum steel uses Conductivity is the aluminum steel of 61.0%IACS, 60.0%IACS or 58.0%IACS.Conducting wire made of the two combination of materials has line loss Greatly, stretching resistance is small, and diameter is big, and gap is larger, and anti-strong wind ability is poor, and coating anti-corrosion grease is easy to pollute the environment, and leads Line construction also bothers.

Utility model content

In order to solve the above technical problems, the utility model provides the energy-saving conductor used under a kind of heavily contaminated environment, Including steel core and the aluminum pipe being coated on outside steel core；Steel core uses structure 1+6,1+6+12 form by intensity >=1900MPa monofilament Mutual close concentric is twisted.Aluminum steel is wrapped outside aluminum pipe；The aluminum steel uses molded line structure, inside and outside adjacent two layers aluminum steel Mutual tight is in aluminum pipe periphery；Steel core filament strength >=the 1900MPa, the molded line structure are that the section of aluminum steel is T Type, S type or Z-type.62.5% ~ 63%IACS of conductivity of aluminum steel.

Further, aluminum pipe is soft-type aluminum pipe.

Further, aluminum steel be conductivity 62.5%IACS high-conductivity hard aluminum molded line or conductivity 63%IACS it is soft Aluminium profiles line.

Compared with the prior art, the utility model has the following advantages:

The utility model steel core using intensity >=1900MPa monofilament using the mutual concentric stranding of structure 1+6,1+6+12 and At aluminum pipe is wrapped aluminum steel outside, and aluminum steel uses molded line structure.Have compared with common steel core anticorrosion conducting wire draw again than it is big, The advantages that gap is small, outer diameter is small, conductivity is high.

The utility model outer layer aluminum steel uses molded line structure, more conductive than the common steel core anticorrosion conducting wire with same cross-sectional Rate improves about 8.0%, improves the conveying capacity of conducting wire, and outer diameter is smaller by about 8.0% than the common steel core anticorrosion conducting wire of same specification, The influence for reducing wind load also can effectively prevent rainwater etc. from entering inside conducting wire using molded line structure, and anti-ice cover is avenged ability and increased By force, the safety and reliability of conducting wire is increased；Conductive line surfaces are smooth, and self-damping performance is more excellent.

Compared with conventional anti-corrosive conducting wire, the utility model is changed production technology, and aluminum pipe is low, conductive using intensity The high soft-type aluminum pipe of rate, is coated on outside steel core, can prevent to generate between steel core and internal layer aluminum steel due to environmental pollution in this way Electrochemical corrosion, crevice corrosion, this structure can substitute completely conventional anti-corrosive conducting wire using coating anti-corrosion ointment come into Row anti-corrosion.The utility model, in this way will not be to environment in process of production without can also reach anti-corrosion effect using anti-corrosion grease Grease is caused to pollute, construction is also easier than coating anti-corrosion grease conducting wire, without wiping grease, not will cause the two of environment when crimping Secondary pollution, and enhance the anti-corrosion capability and conductive capability of conducting wire.

The utility model is suitble to coastal, strong wind be regional and heavily contaminated heavy industrial district uses.

Detailed description of the invention

Specific embodiment

Embodiment 1

Shown in Fig. 1, the energy-saving conductor used under a kind of heavily contaminated environment, it includes steel core 1 and is coated on outside steel core 1 Aluminum pipe 2；Aluminum steel 3 is wrapped outside aluminum pipe 2.The use T-type cable architecture of aluminum steel 3,62.5% ~ 63%IACS of conductivity of aluminum steel 3, Inside and outside adjacent two layers aluminum steel 3 be mutually closely wound with outside aluminum pipe 2；1 filament strength of the steel core >=1900MPa.

Embodiment 2

Shown in Fig. 2, the energy-saving conductor used under a kind of heavily contaminated environment, it includes steel core 1 and is coated on outside steel core 1 Aluminum pipe 2；Aluminum steel 3 is wrapped outside aluminum pipe 2.The aluminium single line 3 uses S type, Z-type molded line structure, and the conductivity 62.5% of aluminum steel 3 ~ 63%IACS, inside and outside adjacent two layers aluminium single line 3 be mutually closely wound with outside aluminum pipe 2；1 filament strength of the steel core >=1900MPa.

In above-described embodiment 1 and 2, steel core 1 can also be placed in centre by 1 aluminum cald steel wire, 6 aluminum cald steel wires and 12 Two layers of mutual close concentric is twisted inside and outside aluminum cald steel wire.

The steel core of the utility model is mutually twisted using intensity >=1900MPa monofilament.Aluminum pipe is using intensity is low, leads The high soft-type aluminum pipe of electric rate is coated on steel core periphery, can be prevent completely between steel core and internal layer aluminum steel in this way due to environment dirt Dye and generate electrochemical corrosion, crevice corrosion.Aluminum steel 3 is wrapped outside aluminum pipe 2, aluminum steel 3 uses molded line structure.With common steel core Anticorrosion conducting wire, which is compared, to be had many advantages, such as to draw again than big, gap is small, outer diameter is small, conductivity is high.

The outer layer aluminum steel of the utility model uses molded line structure, leads than the common steel core anticorrosion conducting wire with same cross-sectional Electric rate improves about 8.0%, improves the conveying capacity of conducting wire, and outer diameter is smaller about than the common steel core anticorrosion conducting wire of same specification 8.0%, the influence of wind load is reduced, also can effectively prevent rainwater etc. from entering inside conducting wire using molded line structure, anti-ice cover avenges energy Power enhancing, increases the safety and reliability of conducting wire；Conductive line surfaces are smooth, and self-damping performance is more excellent.

Compared with conventional anti-corrosive conducting wire, the utility model is changed production technology, and aluminum pipe is low, conductive using intensity The high soft-type aluminum pipe of rate is coated on steel core periphery, can prevent to be produced between steel core and internal layer aluminum steel due to environmental pollution in this way Raw electrochemical corrosion, crevice corrosion, this structure can substitute completely conventional anti-corrosive conducting wire using coating anti-corrosion ointment come Carry out anti-corrosion.The utility model, in this way will not be to ring in process of production without can also reach anti-corrosion effect using anti-corrosion grease Border causes grease to pollute, and construction is also easier than coating anti-corrosion grease conducting wire, without wiping grease, not will cause environment when crimping Secondary pollution.It can prevent completely to occur between steel core and internal layer aluminum steel in the load core of one layer of aluminum pipe of steel core outer cladding composition Electrochemical corrosion enhances the anti-corrosion capability and conductive capability of conducting wire.
