Which statement describes the shielding in LiYCY?

• A. Copper braided shield
• B. Aluminum foil
• C. No shield
• D. Steel mesh

Answer: (A)

Shielding around control cables is there to keep electrical noise out of the conductors and prevent interference in the system. For LiYCY, the shield is a copper braided layer. The braid provides continuous, flexible coverage around the conductors, which is essential in installations that bend and move. Copper braided shielding offers good shielding effectiveness across a broad frequency range and can be easily tied to ground to drain any interference. Aluminum foil shielding would be less flexible and more prone to damage in tight bends, while steel mesh adds significant weight and stiffness and isn’t typical for LiYCY cables. Having no shield would leave the conductors more susceptible to EMI. So, copper braided shield best describes LiYCY.
