CA 250 KCM 7F SNEEZEWORT

Description

Description

Standards

  • Product
    ABNT NBR 7271/88; ASTM B 231

It is an homogeneous conductor stranded with Aluminium 1350, Class AA for bare conductors used in overhead lines.

 

APPLICATIONS

AAC is usually as bare cable for primary and secondary distribution lines with short spans where high mechanical strength is not required. However due to be an Aluminium homogeneous conductor, the Ampacity is very well optimized.

 

CONSTRUCTION

AAC is concentrically stranded conductor with one or more layers of Aluminium wire hard-drawn 1350-H19. The number of wires depends basically on the electrical requirements that will define the size. 

 

Conditions for Ampacity calculation

Conductor temperature = 75 °C;

Room temperature = 25 °C;

Wind speed = 1 m/sec, sunny.
