Answer: The formation of cables refers to the physical arrangement in which single-core cables are laid in a trench. The two primary formations are trefoil and flat. The choice of formation is critical because it directly impacts the cable's performance, safety, and lifespan. The formation influences:

• Heat Dissipation: The ability of the cable to dissipate heat generated by the current.

• Electromagnetic Fields: The strength and balance of the magnetic fields created by the cables.

• Induced Voltage and Current: The amount of circulating current and induced voltage in the cable's metallic sheath, which can cause significant losses.

The correct formation, combined with our high-quality underground cable laying equipment, ensures optimal performance and reliability for the entire cable system.
