Overview
IEC 61196-11:2022 is a crucial international standard developed by the IEC that specifies the general requirements for semi-rigid coaxial communication cables with polyethylene (PE) dielectric and tubular outer conductor. These cables are widely used for high-frequency signal transmission in wireless communication, broadcast television, microwave relay, navigation systems, and RF/microwave electronic equipment. The standard covers materials and construction, IEC type designation, identification, marking and labelling, standard ratings and characteristics, finished cable requirements, quality assessment, and delivery and storage procedures.
This second edition of IEC 61196-11 introduces several significant changes, including more detailed scope descriptions, recommendations for outer diameter ratings of conductors and dielectrics, the introduction of IEC type designations, and comprehensive revisions to standard ratings, characteristics, and finished cable requirements.
Key Topics
-
Cable Construction
IEC 61196-11 specifies construction requirements for:
- Inner conductor (solid or stranded, with detailed diameter and material specifications)
- Polyethylene dielectric (solid, air-spaced, or semi air-spaced)
- Tubular outer conductor (copper or aluminium, either smooth or corrugated)
- Optional sheath for environmental protection
-
IEC Type Designation
Provides a structured system for naming and variant specification, covering characteristic impedance, dielectric diameter, sheath material, and outer conductor structure.
-
Identification, Marking, and Labelling
Ensures each cable is traceable and meets detailed marking rules for correct identification.
-
Standard Ratings and Characteristics
Specifies:
- Nominal characteristic impedance (commonly 50 Ω)
- Temperature ranges for operation, storage, and installation
- Maximum recommended frequencies
- Minimum bending radius (typically 10 times the sheath outer diameter)
- Electrical, mechanical, environmental, and fire performance requirements
-
Testing and Quality Assessment
Details test procedures for continuity, resistance, withstand voltage, insulation, capacitance, impedance, shielding, ageing, cold bend, mechanical stresses, and fire safety.
