High Voltage AAAC Conductor Long Multi Stranded Cable Service Life BS Standard

?

Product Description

?

1. Applications

Conductor(AAC, AAAC and ACSR) have been widely used in power transmission lines with various voltage levels,because they have such good characteristics as simple structure,convenient installation and maintenance,low cost large transmission capacity.And they are also suitable for laying across rivers valleys and the places where special geographical features exist.

?

2. Service Performance

(1). The permissible long-time operating temperature for aerial conductor is 70oC.

(2). Under the circumstance that rare climate is occuring and ice coverage rate low in heavy ice area,the biggest stress of cable at the lowest point of the sag should not exceed 60% of the short-time destructive power.

(3). When connecting conductors,the conductor beside the connecting tube cant be prominent.Otherwise,the force on the operating conductors will be unbalanced.After connectors are install,the connecting tube should be painted by moisture-proof varnish in order to protect it from corrosion.

(4). Under installaion,the arc downing stress of all the conductors should be the same.With in the permissible distance of crossing buildings or dropping to the ground,the stress can be 10-15% higher than regular stress.

AAAC All aluminium alloy conductors for American B-398/ B-399 standard

Detailed Product Description

Applications
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 6201-T81 high strength aluminum conductors, conforming to ASTM Specification B-399, are concentric-lay- stranded, similar in construction and appearance to 1350 grade aluminum conductors. Standard 6201 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 1350 grade aluminum conductors, but without a steel core. The DC resistance at 20°C of the 6201-T81 conductors and of the standard ACSRs of the same diameter are approximately the same. Conductors of the 6201-T81 alloys are harder and, therefore, have a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
Specifications
AAAC bare conductor meets or exceeds the following ASTM specifications :
B-398 Aluminum Alloy 6201-T81 Wire for Electrical Purposes
B-399 Concentric-Lay-Stranded 6201-T81 Aluminum Alloy Conductors.
