EVS-EN 50117-1:2019

This document covers coaxial cables for use in analogue and digital systems. This document should be used in conjunction with EN 50290-1-1.
Coaxial cables covered by this document operate in transverse electromagnetic mode (TEM) and are suitable for use in a wide range of digital and analogue applications including CATV, radio frequency systems, instrumentation, broadcasting, telecommunications and data network systems. Various constructions and materials provide for indoor and outdoor applications, including underground and overhead installations, and other environmental protection characteristics.
Generally, cables are designed for use in 50 Ohm and 75 Ohm characteristic impedance systems, although other types (e.g. 93/95 Ohm) are also covered.
Coaxial cables defined by this document may be incorporated into hybrid cable constructions with optical fibre or multi-element cable components.
All cables covered by this document may be subjected to voltages greater than 50 V AC or 75 V DC according to the relevant sectional or detail specification. However, these cables are not intended for direct connection to the mains electricity supply or other low impedance sources.
