Shielded cables can operate at what voltage level?

Shielded cables are designed to operate at voltage levels of 7200 volts or higher due to their insulation and construction. The shielding in these cables not only protects the inner conductors from electromagnetic interference but also enables them to maintain performance under higher voltage conditions. This feature is especially critical in industrial and utility applications where higher voltage transmission is common.

Options that reference lower voltage levels, such as less than 7200 volts or generally below 600 volts, pertain to other types of cables that do not have the same structure or capabilities as shielded cables. For instance, cables designed for lower voltages typically have different insulation materials and thicknesses, which are not suitable for the demands of higher voltage applications.
