3. Cable installation

Cable installation is the most delicate part of line construction. It involves two main operations:

• unwinding of conductor and ground cables;

• adjusting and clamping cables, and fitting accessories (suspenders, counterweights, spacers, marker balls, etc.).

It is essential to protect cables from any injuries caused by the ground, obstacles, etc., as such injuries greatly increase corona losses (in this treatise, article Corona effect on overhead electrical networks). ).
