Overview

SIST EN 3375-003:2009 is a European standard published by CEN that specifies the requirements for a single braid, 77 Ohms electrical cable type KG, size 24, specifically designed for digital data transmission in aerospace applications. This product standard addresses the construction, general and electrical characteristics, testing methods, quality assurance, identification, and packaging of these specialized cables. It serves as a complementary document to related standards EN 3375-001 and EN 3375-002, providing a comprehensive framework for the design and quality control of aerospace electrical cables.

Key Topics

  • Cable Construction

    • Single braid shield using silver-plated copper strands
    • Two conductors, size 24 AWG compliant with EN 2083
    • Insulation and outer sheath made from fluorocarbon materials
    • Optional tape for enhanced mechanical protection
    • Dimensional specifications ensuring consistent outer diameters and mass per meter
  • Electrical Characteristics

    • Characteristic impedance of 77 ± 7 Ohms at 1 MHz, suitable for digital data signals
    • Nominal capacitance: 70 pF/m, with a maximum of 78 pF/m
    • Maximum attenuation of 3.6 dB per 100 meters at 1 MHz
    • Transfer impedance limits defined for various frequencies to minimize interference
    • Voltage rating up to 600 V AC ensuring operational safety in aerospace environments
  • Performance Parameters

    • Operating temperature range from -65 °C to 200 °C to withstand harsh aerospace conditions
    • Minimum bend radius of 20 mm for flexibility without compromising cable integrity
    • UV laser markability for traceability and identification purposes
    • Specified twisting pitch to optimize cable performance and reduce signal loss
  • Testing and Quality Assurance

    • Comprehensive suite of tests on components and finished cables, including visual, dimensional, electrical, thermal, mechanical, and environmental tests
