What is the purpose of a conductor shield in a cable?

A conductor shield in a cable serves primarily to reduce the possibility of air voids within the cable. This is crucial because air voids can lead to electrical discharges, which can compromise the integrity of the cable and its ability to effectively transmit power. By minimizing or eliminating these voids, the conductor shield enhances the cable's overall performance and reliability.

While other aspects of cable construction can contribute to moisture protection and tensile strength, the central function of the conductor shield is specifically aimed at addressing the risk posed by air gaps. Thus, the importance of maintaining an effective conductor shield cannot be overstated as it ensures a more stable and efficient operation of the electrical system.
