Overview - EN 4604-005:2015 (coaxial cable, 75 Ω, 200 °C, type WL)
EN 4604-005:2015 is a CEN / ASD-STAN aerospace product standard that defines the required characteristics for a 75 ohm coaxial cable (type WL) intended for aircraft electrical systems. The standard covers material, construction, electrical and mechanical properties, environmental limits and test methods for use at operating temperatures from −55 °C to 200 °C and for high-frequency signal transmission up to 3 GHz.
Key topics and technical requirements
- Materials and construction
- Conductor: multi-stranded high-strength copper alloy, silver-plated (≥1 µm); strand configuration listed (0.30 ± 0.025 mm, 7×0.10 mm).
- Dielectric and jacket: fluorocarbon materials; jacket colour medium blue.
- Shield: double-braid per ASTM-B298-12, silver-plated strands.
- Overall cable: maximum outer diameter and mass specified (max ~2.35 mm, mass ~12.5 g/m).
- Electrical characteristics
- Characteristic impedance: 75 ± 5 Ω.
- Capacitance: ≤ 60 pF/m.
- Transfer impedance: ≤ 30 mΩ/m up to 100 MHz.
- Operating voltage: 500 V RMS max.
- Velocity of propagation: ≥ 0.74 c (≥ 222 000 km/s).
- Frequency performance: attenuation and power-handling defined up to 3 GHz (representative values shown in the standard - e.g., attenuation increases from ~10 dB/100 m at 10 MHz to ~176 dB/100 m at 3 GHz; power handling decreases from ~500 W at 10 MHz to ~52 W at 3 GHz).
- Mechanical & environmental
- Operating temperature range: −55 °C to 200 °C.
- Minimum bend radius: static 15 mm, dynamic 25 mm.
- Delivery: cable drums (~200 m), minimum piece length 50 m.
- Testing & quality
- Test suite referenced to EN 3475-100 (electrical and environmental tests), with specific pass criteria (e.g., insulation resistance > 5 000 MΩ between shield and conductor; plating thickness ≥ 1 µm).
- Quality assurance and marking follow EN 4604-001 and EN 4604-002.
Applications and who uses this standard
- Intended users: avionics engineers, cable manufacturers, aircraft OEMs, procurement teams, quality & test laboratories, and maintenance organizations.
- Typical applications: high-frequency signal transmission in aircraft systems (radio, navigation, radar, data links) where high temperature resistance and controlled RF performance (up to 3 GHz) are required.
