overhead line conductor

1. Applications: Conductor(AAC 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. Standard:

The hard aluminum conductor used for AAC and ACSR conforms to the standard IEC 60889: 1987.

3. DIN standard code number(mm2):

   16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 625, 800, 1000

4. Service Performance:

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

c.  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.

d.  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.

All aluminum conductor

Application:

a) This product is widely used in overhead electric power transmission and distribution lines with various grade voltages.

b) Under the same weight, AAC is with higher DC resistance and lower cost than Copper conductor.

 

c) Aluminum is light and be easy to lay.

Standard:   IEC61089, BS215 part1, DIN48201 part5, ASTM B231, BS EN50182
