BS EN 50117-9-3:2019 pdf free.Coaxial cables.
Cables according to this standard are designed for an operating temperature range from – 40 °C to +70 °C1 and at frequencies between 5 MHz and 6 000 MHz.
When designing the cable, consideration should be given to the maximum admissible current stated in the detail specification. It is assumed that the raise of temperature of the inner conductor when submitted to the maximum current under nominal ambient conditions does not affect the mechanical and electrical properties of the cable.
Cables according to this standard may be operated at voltages > 50 V AC or >75 V DC according to the detail specification of the manufacturer. However, these cables are not intended for direct connection to the mains electricity supply or other low impedance sources.
Cables according to this standard shall be designed according to EN 50290-2-1, Communication cables Part 2-1: Common design rules and construction. They shall be used according to EN 50290-4-1, Communication cables – Part 4-1: General considerations for the use of cables – Environmental conditions and safety aspects.
The use of cables according to this standard including delivery, storage and installation shall be in accordance with EN 50290-4-2, Communication cables – Part 4-2: General considerations for the use of cables – Guide to use, unless otherwise specified.
Cables according to this standard shall be tested for voltage withstanding. The test is performed between conductors and between the conductors or screen and the outer surface of the sheath.
When constwcted in accordance with EN 50290-2-1 and EN 50117-1 and submitted to spark testing, CATV cables according to this standard may be installed together with Low Voltage cables.
All cables covered by this standard do not fall under the scope of the RED or the EMC directive. Nevertheless, transfer impedance and screening attenuation according to 5.1.3.6 and 5.1.3.7 shall be specified in the relevant detail specification, if the intended application of the cable is the use in combination with equipment under the RED or the EMC Directive. The conductor shall meet the requirements of 4.2 of EN 50117-1:2019, and shall be solid and may be plain or metal coated. Dimensions shall be in accordance with the detailed specification.BS EN 50117-9-3 pdf download.
