Overhead Transmission Line 800mm2 AAAC All Aluminum Alloy Conductor Cable

Overhead Transmission Line 800mm2 AAAC All Aluminum Alloy Conductor Cable

Aaac alloy overhead Conductor 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.

AAAC 6201-T81

AAAC 6201-T81 Applications

The bare aluminum alloy conductors type AAAC (All Aluminum Alloy Conductor) 6201-T81 stranded classes AA and A are used for transmission and distribution lines of electric power, when for reasons of design of the line, a high tensile stress is needed (even bigger that the obtained with 5005-H19) and a high ratio mechanical stress-weight for the optimization of the sags in long spans. These conductors are especially useful for installation in coastal areas or of high environmental corrosion, where the ACSR cannot be used.

AAAC 6201-T81 Specifications

The bare aluminum alloy conductors AAAC 6201-T81 manufactured by ELECTROCABLES C.A., meets the following specifications and standards:

• ASTM B-398: Aluminum Alloy Wires 6201-T81 for electric purposes.
• ASTM B-399: Aluminum Alloy Stranded conductors 6201-T81in concentric layers.

AAAC 6201-T81 Construction

The bare aluminum alloy conductors type AAAC 6201-T81 are concentrically stranded, and they are built with wires of this alloy. Their packaging is in reels in lengths according to the client's necessities.

Aluminum Conductor 6201 - T81

Aluminum Alloy Conductors A.A.A.C 6201-T81

CONDUCTOR MANUFACTURED UNDER STANDARDS:ASTM B-398 • ASTM B-399 • INEN

PACKAGING:For all sizes
Z - Length as per customer's requirements.
AMPACITY IN AMPERES:
Calculated for a conductor temperature of 75 ºC, ambient temperature 25 ºC, emissivity of 0.5, wind of 0.61 m/sec. and with sun effect (1033 watts/m²).

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

(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.
