Abstract
A cable comprises a power conductor, a data conductor and a first PTC device. The power conductor is configured to transmit electrical power between a source and a sink. The data conductor is configured to transmit data between the source and the sink. The first PTC device is coupled to the data conductor and its resistance increases drastically to decrease current flowing through the data conductor if a temperature of the first PTC device exceeds a first trip temperature. The first trip temperature is 55-80° C. The resistance of the PTC device is larger than 20 kΩ at 85° C. and larger than 80 kΩ at 100° C. A current flowing through the data conductor does not exceed 20 mA.
