适用范围：This sectional specification covers multi-element cables suitable for connecting instruments andcontrol systems for analogue or digital signal transmission. They may or may not be screenedand optionally may incorporate armouring and/or moisture or environmental protection layers.The cables shall have a mechanically robust construction and electrical transmission handlingproperties. The electrical, mechanical, transmission and environmental performancecharacteristics of the cables, related to their reference test methods are detailed.This sectional specification is to be read in conjunction with EN 50288-1, which contains theessential provisions for its application.Cables covered by this specification have maximum rated voltages of 90 V, 300 V and500 V a.c.These cables shall not be connected directly to mains electricity supply or other low impedancesources. Multi-element cables for use in analogue, digital and control circuits are not designedto be used for power supply.These cables should be installed in accordance with the applicable local and nationalregulations.Cables intended to have limited circuit integrity in a fire are not covered by this specification, butthey are however under consideration for future editions.There may be occasions when cables are required to have higher operating temperatureratings than those provided by using materials specified by the EN 50290 series. Suitablealternative materials are under consideration.
