22、or instrumentation, inter-connection of equipment and information technology cabling applications. Cables for information technology cabling systems, covered by this and the sectional specification standards in the EN 50288 series are suitable for use in digital and analogue data systems meeting the
23、 requirements, for example, of EN 50090-2-1, EN 50090-3-1, EN 50098-1, EN 50098-2 and EN 50173. Unless otherwise specified, all cables covered by this European Standard may be subjected to voltages greater than 50 V a.c or 75 V d.c. but not more than 300 V a.c. or 450 V d.c. and shall meet the essen
24、tial requirements of the low voltage directive. Due to current limitation related to the conductor cross sectional area, they are not intended for direct connection to mains electricity supply. The maximum current rating per conductor is as stipulated in Table B.1 unless otherwise specified in the r
25、elevant sectional specification. IDCs are only designed for copper or metal coated copper. Cabling elements as defined in 4.3 of this European Standard may be incorporated in hybrid construction cables together with coaxial or optical fibre cabling elements. 2 Normative references The following docu

39、nductors Conductors are to be solid or stranded copper as specified in the relevant EN 50288 sectional specification. The conductivity of copper conductors shall be in accordance with IEC 60028. Stranded conductors shall consist of wires circular in section and assembled, without insulation between
40、them, by concentric stranding or bunching. As most of these cables are used together with insulation displacement connecting devices (IDC), a maximum of seven strands should be used. The solid conductors or the individual wires of stranded conductor may be plain or metal-coated. There shall be no jo
41、int in the wire made subsequent to the last wire drawing operation. Joints in individual strands of a stranded copper inner conductor shall be cold pressure welded, brazed or silver soldered using a non acid flux such that the strand diameter shall not be increased. No joint in an individual strand
42、shall be within 0,3 m of a joint in any other individual strand. The nominal conductor diameter is given in the relevant sectional specification. Other diameters or stranded conductors are to be agreed between manufacturer and purchaser and specified in Annex B of the relevant sectional specificatio
43、n. 4.2 Insulation The choice of the insulating material shall take into account electrical and environmental requirements. The insulation material(s) shall meet the requirements of the relevant part or parts of EN 50290-2, or otherwise as detailed in the relevant sectional specification. Conductor i
44、nsulation shall be composed of one or more suitable dielectric materials. The insulation may be solid, cellular or composite (e.g. foam-skin). The insulation shall be continuous, having a thickness as uniform as possible. When required, the thickness of the insulation shall be measured in accordance
45、 with the method specified in EN 60811-201. The insulation shall be applied to fit closely to the conductor. When required, the stripping properties of the insulation shall be checked in accordance with the method specified in EN 50289-3-17. When not used with IDC termination, it shall be possible t
46、o strip the insulation from the conductor easily and without visible damage to the conductor, its coating, or the insulation remaining on the conductor. 4.3 Cable elements The cable element is - a single insulated wire, or - a pair consisting of two insulated conductors twisted together and designat
47、ed wire “a” and wire “b”, or - a triple consisting of three insulated conductors twisted together and designated wire “a”, wire “b” and wire “c” in order of rotation, or - a quad consisting of four insulated conductors twisted together and designated wire “a”, wire “c”, wire “b” and wire “d” in orde
48、r of rotation. Wires “a” and “b” form pair 1 and wires “c” and “d” form pair 2.
