Overview

EN 4681-005:2019 is the CEN product standard for the AZ family of single-core, general-purpose aerospace electrical cables intended for use in low-pressure atmospheres. The standard covers cables for aircraft electrical networks at 115 V (phase to neutral) / 200 V (phase to phase) and 230 V / 400 V networks, with particular emphasis on use in non-pressurized areas. Operating temperature range is -65 °C to 180 °C.

These cables use conductors made from nickel-plated aluminium alloy (code D) in accordance with EN 3719 and are manufactured as single cores with defined colour coding and identification per EN 4681-002 and EN 4681-001.

Key Topics

• Conductor material: Nickel-plated aluminium alloy (code D) for specified nominal section codes.
• Construction: Single-core design; insulation materials must satisfy Clause 5 characteristics; foamed insulation is forbidden.
• Electrical ratings: Suitable for 115/200 V and 230/400 V aircraft networks.
• Temperature range: Qualified for continuous operation between -65 °C and 180 °C.
• Partial discharge control: Insulation design limits cavities and gas traps; no external wrinkles at minimum bend radius.
• Testing and qualification: Requirements reference EN 3475-100 test methods and EN 4681-001 technical specification. Key tests include visual, dimensions, ohmic resistance, voltage proof, insulation resistance, corona extinction voltage (at 45 000 ft and 150 °C with PDIV ≥ 566 Vr.m.s. and PDEV ≥ 509 Vr.m.s.), thermal ageing and flammability.
• Mechanical characteristics: Minimum bend radius follows EN 4681-001 Table 4; flexibility and tensile parameters referenced in the standard.
• Marking and packaging: Identification, marking and delivery lengths follow EN 4681-002 and EN 4681-001.

Applications

EN 4681-005:2019 AZ family cables are optimized for practical aerospace uses where weight, thermal endurance and low-pressure performance are required. Typical uses include:

• Internal aircraft power distribution in non-pressurized zones.
• Systems requiring stable performance across a wide temperature envelope (-65 °C to 180 °C).
• Installations where aluminium-based conductors are preferred for weight savings with nickel plating for conductivity and corrosion resistance.

Benefits for design and procurement:

• Assured compatibility with aerospace network voltages.
• Standardized testing and qualification paths reduce development risk.
• Clear marking and designation simplify inventory and installation.

Related Standards

• EN 3719 - Aluminium or aluminium alloy conductors (product standard)
• EN 4681-001 - Technical specification for the cable family
• EN 4681-002 - General requirements and colour coding
• EN 3475-100 - Test methods (general)
• EN 9133 - Quality management and qualification procedure for aerospace standard products

For designers and procurement teams, EN 4681-005:2019 provides a concise product standard that ensures AZ family single-core cables meet the electrical, mechanical and environmental demands of modern aircraft low-pressure applications.
