Aerospace series - Cable, electrical, for signal transmission - Part 010 : Cable, coaxial, light weight, 50 Ohms, 200 °C, type KX (light WD) - Product standard

This European Standard specifies the required characteristics of a light weight coaxial cable, 50 Ω, type KX
for use in aircraft electrical systems at operating temperature between − 55 °C and 200 °C and specially for
high frequency up to 6 GHz. Nevertheless, if needed, − 65 °C is also acceptable as shown by rapid change of
temperature test.

Ta evropski standard določa zahtevane lastnosti lahkega koaksialnega kabla, 50 Ω, tipa KX za uporabo v letalskih električnih sistemih pri obratovalni temperaturi med −55 °C in 200 °C ter posebej za visoko frekvenco do 6 GHz. Vseeno je po potrebi sprejemljiva tudi temperatura −65 °C, kot prikazuje preskus s hitro spremembo temperature.

Overview

EN 4604-010:2018 is a CEN aerospace product standard that specifies the required characteristics for a light weight 50 Ω coaxial cable, type KX, intended for aircraft electrical systems. The standard covers material, construction, electrical performance and test requirements for a coaxial cable designed for operating temperatures from −55 °C to 200 °C (−65 °C acceptable in rapid-change tests) and for high‑frequency signal transmission up to 6 GHz.

Key topics and technical requirements

• Cable type and purpose: Light weight coaxial cable, 50 Ω, Type KX (light WD) for signal transmission in aerospace/avionics applications.
• Materials:
  • Conductor: single‑strand copper, 1 µm silver‑plated (per ASTM‑B298).
  • Dielectric and jacket: fluorocarbon materials; jacket colour specified as light green.
  • Screen: silver‑plated tape and braided silver‑plated copper (per ASTM‑B298).
• Electrical performance:
  • Characteristic impedance: 50 ± 2 Ω at 200 MHz.
  • Capacitance: ≤ 88 pF/m.
  • Performance guaranteed to 6 GHz; attenuation, VSWR and power handling defined in tabulated frequency ranges.
  • Operating voltage: 1 000 V rms max.
  • Transfer impedance limits provided across frequency bands.
• Mechanical / environmental:
  • Operating temperature range: −55 °C to 200 °C (rapid change test allows −65 °C).
  • Minimum bend radius: 30 mm (static), 50 mm (dynamic).
  • Delivery lengths typically on drums (~175 m), minimum piece 50 m.
• Testing and quality:
  • Extensive test suite referenced to EN 3475 series (visual, dimensional, ohmic resistance, voltage proof, insulation resistance, transfer impedance, attenuation, thermal and mechanical tests).
  • Quality assurance and identification requirements reference EN 4604‑001 and EN 4604‑002.

Applications and who uses it

• Used by aerospace and defence OEMs, avionics designers, harness manufacturers, procurement/specification engineers and maintenance/repair organizations requiring reliable RF signal transmission in aircraft.
• Typical applications: onboard RF and data links, antenna feeder lines, instrumentation and high‑frequency signal routing where low mass, high temperature tolerance and controlled impedance are critical.
