Cables are broadly categorized based on their construction and application, including power cables, control cables, and data cables. Power cables are designed to transmit electrical energy and are characterized by their robust insulation and conductor size to handle high voltages and currents. Control cables, often used in automation and machinery, are flexible and shielded to transmit signals accurately while resisting electromagnetic interference. Data cables, such as Ethernet or fiber optic cables, prioritize high-speed signal integrity and bandwidth, making them essential for communication networks.
