What is the standard voltage for coaxial cable?

Coaxial cable does not have a standardized voltage in the same way that specific electrical appliances or circuits do. Instead, coaxial cable is designed to transmit signals, such as cable television or internet data, rather than electrical power. The voltage level that might be present on coaxial cables varies depending on the application and the signal being transmitted. For example, in the case of cable television, the signals transmitted can range from a few millivolts to several volts, but these do not represent a standardized voltage.

The rationale behind stating that no standard voltage exists is due to the diverse ways coaxial cables are used across various systems and technologies. Each system may use different types of signals with corresponding voltage levels that suit their specific requirements, making it impossible to apply a universal voltage standard to all coaxial cables.
