UL20744 High-Speed Data Cable – Flat or Round Cable for Signal Transmission
UL20744 cable is a UL-certified high-speed signal and data cable designed for modern electronic systems requiring high-frequency, high-density transmission. Commonly used in servers, storage systems, industrial automation, and advanced electronics, it offers a variety of conductor configurations (2 to 200 cores), insulation types, and flexible structures such as flat ribbon or round bundled formats.
With rated voltages of 30V or 150V and temperature ratings up to 80°C, UL20744 cables are built to handle tight routing, mechanical movement, and stable signal integrity in complex, space-constrained installations. Available shielding options provide enhanced EMI resistance, and all constructions meet UL758 AWM requirements for flame and electrical safety.
