Bare Conductor (AAC/ACSR/AAAC/ACAR/AACSR/ACS/GSW)

タイトルまたは説明

1. All Aluminum Conductor(AAC)

Application
The conductors are suitable for use in spans on wood poles, transmission towers,and other structures where tensile strength and temperature ratings are not required. Application range from extra high voltage(EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises.
AAC(All aluminum conductor) is the most economical bare overhead conductor due to its lighter weight. It offers easier handing during installation and use of simpler fittings. The conductor is corrosion resistant due to its homogeneous construction.
 
 
Construction
Aluminum ***0 wires are concentrically stranded and wrapped helically around a central wire. Each successive layer has six wires more than the previous underlying layer. Outer layer is right hand lay and reversed in successive layers.

2. Aluminum Conductor Steel Reinforced(ACSR )

Application
The conductors are suitable for use in all practical spans on wood poles, transmission towers,and other structures. Application range from extra high voltage(EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises.
ACSR(Aluminum Conductor Steel Reinforced) has a long service record because of its economy ,dependability, and strength to weight ratio. The combined light weight and high conductivity of aluminum with strength of the steel cores enable higher tensions ,less sag,and longer spans than any alternative.
 
Construction
Aluminum ***0 wires and the steel cores are concentrically stranded and wrapped helically around a central wire. The additional corrosion protection is available through the application of grease to the cores or infusion of the complete cable with grease.

3. All Aluminum Alloy Conductor(AAAC)

Application
Used as bare overhead conductor for primary and secondary distribution. Designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio; affords better sag characteristics. Aluminum alloy gives AAAC higher resistance to corrosion than ACSR.
 
Construction
Standard ****-T*1 high strength aluminum conductors, conforming to ASTM Specification B***9, are concentric-lay-stranded, similar in construction and appearance to ***0 grade aluminum conductors. Standard ***0 alloy conductors are similar to other alloy conductors commercially known as Ardival, Aldrey or Almelec. They were developed to fill the need for an economical conductor for overhead applications requiring higher strength than that obtainable with ***0 grade aluminum conductors, but without a steel core. The DC resistance at *0 °C of the ****-T*1 conductors and of the standard ACSR of the same diameter are approximately the same. Conductors of the ****-T*1 alloys are harder and , therefore, have a greater resistance to abrasion than conductors of ****-H*9 grade aluminum.

B **8 Aluminum Alloy ****-T*1 Wire for Electrical Purpose
    B **9 Concentric-lay-stranded ****-T*1 Aluminum Alloy Conductor

4. Aluminum Conductor Alloy Reinforced(ACAR)

Application
The aluminum conductor alloy reinforced(ACAR) is an excellent conductor choice where current carrying capacity,higher strength and a lower conductor weight are critical to the line design.
 
Construction
The aluminum conductor alloy reinforced(ACAR) has concentrically stranded aluminum ****-H*9 wire around a ****-T*1 aluminum alloy core. Typically, the ****-T*1 is the conductor core,but in certain designs, the ***0 H*9 and the ****-T*1 wires may be stranded in the same layer.
