What voltage can unshielded cables operate up to?

Unshielded cables are generally used for lower voltage applications due to their susceptibility to electromagnetic interference and environmental factors. In many cases, their maximum operational voltage typically does not exceed 7200 volts. This limitation ensures safety and reliability, allowing for effective performance while minimizing the risk of electrical failures that could arise from using unshielded cables at higher voltage levels.

On the other hand, higher voltage requirements often necessitate the use of shielded cables, which provide additional protection against interference and ensure better insulation properties. Hence, while unshielded cables may be adequate for voltages less than 7200 volts, higher voltages would typically require alternative types of cables specifically designed to handle those conditions safely.
