21、poses and for special applications such as hoists and travelling cranes. Cables of composite construction (for instance, cables with cores of different sizes) are not specified, but conditions are given for the inclusion of telecommunication units into the cables. NOTE 1 This revision is in accordan
22、ce with an agreement with CEN TC 10 to specify in the same standard a) flexible cables for lifts as required by EN 81, and b) flexible cable for applications such as hoists and travelling cranes, previously found in HD 359. In accordance with this agreement only those cables in Clauses 5 and 6 are s
23、uitable for use with EN 81. NOTE 2 The limits for the overall diameter of the cables have been calculated in accordance with EN 60719. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、basis, in order to demonstrate satisfactory performance characteristics to meet the intended application. These tests are of such a nature that, after they have been made, they need not be repeated unless changes are made in the cable materials, design or type of manufacturing process which might ch

34、e between any insulated conductor and “earth“ (metal covering of the cable or the surrounding medium); U being the r.m.s. value between any two phase-conductors of a multicore cable or of a system of single-core cables. In an alternating current system, the rated voltage of a cable shall be at least
35、 equal to the nominal voltage of the system for which it is intended. This condition applies both to the value Uoand to the value U. In a direct current system, the nominal voltage between conductors shall be not higher than 1,5 times the rated voltage (U) of the cable, and the nominal voltage betwe
36、en any conductor and earth shall not be higher than 1,5 times the rated voltage (Uo) of the cable. NOTE The operating voltage of a system may permanently exceed the nominal voltage of such a system by 10 %. A cable can be used at a 10 % higher operating voltage than its rated voltage if the latter i
37、s at least equal to the nominal voltage of the system. 7 EN 50214:2006 3.4 freely suspended length the unsupported allowed length of cable between two fixing points 3.5 strain bearing member (sbm) metallic or non-metallic high tensile strand or bunch included in the cable construction in order to ho

39、are harmonised. For cables with five cores or fewer, the identification of the remaining cores shall be either by colours, in accordance with a) below, or by numbers in accordance with b) below. For cables with six cores or more only identification by numbers shall be used, except for any green-and-
40、yellow core. a) Identification by colours The identification system of HD 308 shall be used. b) Identification by numbers Identification by numbers shall be in accordance with EN 50334. The green-and-yellow core, if any, shall not be identified by a number. 4.3 Telecommunication Units It shall be pe
41、rmitted to introduce telecommunication units into the cable construction described in Clauses 5 and 6, subject to the following conditions: 1) units shall be chosen from copper pairs or copper coaxial or optical fibres; NOTE Two pairs may alternatively be included as a quad. 2) units shall have a di
42、ameter equal or very close to the diameter of insulated cores; 3) preferably the number of telecommunication units in a cable shall not exceed three; 4) the position of units shall be central and symmetrical; 5) thickness (e2) of the cable sheath, where measured over telecommunication units, shall c
43、omply with the requirements for minimum thickness (see 5.3.5 and 6.3.5) but shall not be taken into account when calculating the mean value; 6) the colour or identification of the outer sheath over units shall not conflict with that of the cores in 4.2. However, no restriction shall be placed on col
44、ours used for insulations under an outer sheath.
