60227 IEC 71c

What is 60227 IEC 71c cable?

60227 IEC 71c: circular PVC lift cable and cable for flexible connections, 300/500 V up to 1 mm2, 450/750 V above. Rating: 300/500 V up to 1 mm2, 450/750 V above; preferred 6 to 30 cores of 0.75 to 2.5 mm2, 4 or 5 cores of 4 to 25 mm2; class 5 (resistance +5 % up to 2.5 mm2); PVC/D insulation, PVC/ST5 sheath; 70 C (IEC 60227-6 cl. 4, Tables 7 and 8). Standard: IEC 60227-6 (clause 4).

IEC 60227-6 (standard, scope and constructions read): circular lift cable and cable for flexible connections; 300/500 V up to 1 mm2 and 450/750 V above; preferred 6 to 30 conductors of 0.75 to 2.5 mm2, 4 or 5 of 4 to 25 mm2; class 5 conductors, resistance +5 % up to 2.5 mm2; telecommunication units (optical fibre, coaxial, screened pairs) may be laid up with the cores; PVC/D insulation, PVC/ST5 sheath; 70 C. The dimensions of Table 8 are not transcribed. The 'c' (circular) is part of the code. Drawn with six cores when no count is typed. IEC 60227-6 has no core clause of its own; its scope (cl. 1, p. 9) sends every cable to IEC 60227-1. Core colours (IEC 60227-1:2007 4.1.2, p. 9): one and two cores no preferred scheme; three cores green-and-yellow, blue, brown or brown, black, grey; four cores green-and-yellow, brown, black, grey or blue, brown, black, grey; five cores green-and-yellow, blue, brown, black, grey or blue, brown, black, grey, black; above five cores by number (4.1.1, 4.2). Drawn with the green-and-yellow set when the size says so (3G1.5), otherwise the set without it; two cores are drawn brown and blue (the HD 308 pair, as the standard prefers none); above five cores black numbered cores, the green-and-yellow core last. Code designation (IEC 60227-1:2007 Annex A, p. 20): the first numeral is the basic class (0 non-sheathed for fixed wiring, 1 sheathed for fixed wiring, 4 non-sheathed light duty flexible, 5 sheathed normal duty flexible, 7 sheathed special duty flexible), the second the type within the class, so the number is read whole. The old spelling drops the 60 ('227 IEC 53' = '60227 IEC 53', IEC renumbering); Helukabel's table prints 227 / 245, EN-JV and Top Cable 60227.
