ČSN EN 4681-003

This document specifies the characteristics of UV laser printable electrical lightweight wires AD family for use in the on-board 115 V (phase to neutral) or 200 V (phase to phase) AC, 28 VDC electrical systems of aircraft at operating temperatures between -65 °C and 180 °C. These cables are demonstrated to be arc resistant in sizes AWG 24 to 14 (115 VAC/200 VAC). In addition, these cables are suitable for use at 230 VAC/400 VAC in pressurized zones only when installed to take account of possible short circuit effects. Other electrical system configurations are the responsibility of the users. It is also possible to mark these cables by qualified compatible marking which satisfies the requirements of EN 3838:2022.
