Cross-Arms Assignment Help

Assignment Help: >> Overhead Lines - Cross-Arms


The shape and length of the cross-arms depend upon the desired configuration of conductors. The subsequent types of cross-arms and brackets are used:

-V cross-arms for tangent locations with clamps;

-Double channel cross-arms for tension or cut point locations while double poles are used; and

- Top clamps.

Cross-arms of hand wood (sisso, sal), or creosoted soft wood (chir) or fibre glass are mostly used. Steel cross-arms are stronger and last much longer. MS angle iron and channel iron sections are generally used for these reasons. Smaller sections are used for communication circuits.
