Partially true. Coaxial cable is similar to that used for cable television as it is a type of cable that is used for transmitting electrical signals. However, the statement that it consists of thickly insulated copper wire is not entirely accurate. Coaxial cable actually consists of a copper core that is surrounded by insulation, which is in turn surrounded by an outer conductor and a sheath. This design helps to reduce interference from external electrical signals, making coaxial cable suitable for use in a wide range of applications, including data communication, video transmission, and telecommunications.
