What is BS EN 50117‑9‑1 - Coaxial cables about ?
BS EN 50117 is a series on coaxial cables. Coaxial cables are a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket. BS EN 50117‑9‑1 is a sectional specification that applies to coaxial indoor drop cables for analogue and digital one and two-way signal transmission, e.g., for cable networks for television signals, sound signals and interactive services. BS EN 50117‑9‑1 also includes the transmission of BCT signals provided by a CATV, MATV or SMATV cable network.
The purpose of BS EN 50117‑9‑1 is to specify the applicable test methods and requirements for the electrical, mechanical, and environmental characteristics and for fire performance of the cables.

Why should you use BS EN 50117‑9‑1 - Coaxial cables ?
BS EN 50117‑9‑1 implementation offers you the benefits of a coaxial cable that has high bandwidth through which a large amount of data can be transmitted for a long distance. Cables according to BS EN 50117‑9‑1 are designed for an operating temperature range from -40 °C to +70 °C1) and at frequencies between 5 MHz and 1 000 MHz. When designing the cable, consideration is given to the maximum admissible current stated in the detailed specification. It is assumed that the rise 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 BS EN 50117‑9‑1 may be operated at voltages > 50 V AC or >75 V DC according to the detailed specification of the manufacturer. However, these cables are not intended for direct connection to the mains electricity supply or other low impedance sources.
All cables covered by BS EN 50117‑9‑1 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 is specified in the relevant detail specification, if the intended application of the cable is used in combination with equipment under the RED or the EMC Directive. Its locating capability and easy installation make BS EN 50117‑9‑1 more convenient for indoor applications. Using BS EN 50117‑9‑1 you can understand sectional specification that applies to coaxial indoor drop cables for analogue and digital one and two-way signal transmission.
