18、 standard covers the Principle Elements of the Safety Objectives for Electrical Equipment Designed for Use within Certain Voltage Limits (LVD - 2006/95/EC). BS EN 50288-1:2013EN 50288-1:2013 - 4 - 1 Scope When used together with EN 50290 and EN 50289, this European Standard covers cables for instrum
19、entation, 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 requireme
20、nts, 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 essential requi
21、rements 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 relevant se
22、ctional 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 documents, in

BS EN 50288-1:2013EN 50288-1:2013 - 6 - 4 Requirements for cable construction 4.1 Conductors Conductors are to be solid or stranded copper as specified in the
35、 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 them, by concentric stranding or bunching. As most of these cables are use
36、d 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 joint in the wire made subsequent to the last wire drawing operation. Joints
37、 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 shall be within 0,3 m of a joint in any other individual strand. The nomin
38、al 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 specification. 4.2 Insulation The choice of the insulating material shall take into ac
39、count 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 insulation shall be composed of one or more suitable dielectric materials.
40、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 with the method specified in EN 60811-201. The insulation shall be applie
41、d 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 to strip the insulation from the conductor easily and without visible damag
42、e 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 designated wire “a” and wire “b”, or - a triple consisting of three insulated cond
43、uctors 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 order of rotation. Wires “a” and “b” form pair 1 and wires “c” and “d” form pa
44、ir 2. BS EN 50288-1:2013- 7 - EN 50288-1:2013 The choice of the lay length of the cable elements in the finished cable shall take into account the transmission requirements, handling performance and identification. 4.4 Identification of cabling elements When required, the insulated conductors shall
45、be identified by colours and/or additional ring markings and/or symbols achieved by the use of coloured insulation or by a coloured surface using extrusion, printing or painting. Colours shall be clearly identifiable and shall correspond reasonably with the standard colours shown in HD 402 S2. The c
46、olour(s) or the symbol used for core identification shall be durable such that it cannot be removed when tested to EN 50289-3-8. 4.5 Screening of cabling elements When required by the relevant sectional specification the cabling elements shall be screened by one or any combination of the following:
47、- a metal tape; - a metal tape laminated to a plastic tape; - a plain or coated metal braid; - a helical wrap of parallel copper wires; - a semi-conducting layer. If a drain wire is incorporated, it shall be in contact with the screen element. The drain wire shall be either solid or stranded, made o
48、f plain or metal coated copper wire. Care should be taken when placing dissimilar metals in contact with each other. Coatings or other methods of protection may be necessary to prevent galvanic interaction. A protective wrapping may be applied under and/or over the screen. Elements of screening cons
49、truction (e.g. drain wire, metal tape, helical wrapping), materials (e.g. plain or plated copper) and dimensions, if required for screening efficiency are to be agreed between manufacturer and purchaser and specified in Annex B of the relevant sectional specification. 4.6 Cable make-up The cable elements may be laid up in concentric layers or in unit construction. The cable core assembly may be protected by wrappings of non-hygroscopic tape. NOTE When required by the sectional specification, units are identified by the use of coloured or numbe
