Aluminum alloy strand conductor

AAAC 's 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?Cof 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

The permissible long-time operating temperature for aerial conductor is 70.

The circumstance that long distance rare climate and ice coverage rare occurring in heavy ice area, the most biggest stress of cable at the lowest arc downing point should not exceed 60% of the distructive power at a short time.

When connecting conductors, the conductor near to the connecting tube can`t be prominient.Otherwise, the force on the operating conductors will be unbalanced after connectors are pressed, the connecting tube should be plated ny moistureproof paint in order to protect from corroding.

Under installation, the arc downing stress of all the conductors at home distance ot the ground and across building can be 10-15% higher than regular tension.

Remarks
Any crush or bump should be avoided during handling and transportation of the product.

The cable drum is not allowed to be placed with one flange up and the other down during transportation and storage of the products.

A moisture-proof measure should be taken during storage of the product
