60245 IEC 70

What is 60245 IEC 70 cable?

60245 IEC 70: braided lift cable, 300/500 V. Rating: 300/500 V; 6, 9, 12, 18, 24 or 30 cores of 0.75 or 1 mm2, class 5 (resistance +5 %); IE4 rubber insulation 0.8 mm; overall textile braid; 60 C (IEC 60245-5 cl. 2, Table 1). Standard: IEC 60245-5 (clause 2); code IEC 60245-1 Annex A.

IEC 60245-5 (standard): clause 2, braided, tough rubber or polychloroprene sheathed lift cable for normal use (2, p. 11): 70 braided, 74 tough rubber sheathed, 75 polychloroprene or other equivalent synthetic elastomer sheathed (2.1); 300/500 V (2.2); 6, 9, 12, 18, 24 or 30 conductors (other counts not precluded), class 5 with the maximum resistance raised 5 %, plain or tinned (2.3.1); rubber insulation IE 4 (2.3.3 as amended by Amendment 1, 2003; IE 1 in the 1994 text), an optional textile braid on each core (2.3.4); the cores twisted round a central heart of hemp, jute or the like, which may carry a strain-bearing member covered with non-conducting material, in one layer up to 12 cores and one or two above (2.3.5, 2.3.6, p. 13); cores identified as IEC 60245-1 4.1 or 4.2 (2.3.6); Table 1 (p. 15): 6, 9, 12, 18, 24, 30 x 0.75 (non-preferred) and x 1 mm2, insulation 0.8 mm (0.6 mm for 0.75 mm2 cores under a textile braid); the overall diameter is not specified (2.3.8); 60 C in normal use (2.5, p. 15). Outer covering (2.3.7.1, p. 13): an optional inner textile braid or proofed textile tape (lapped at least 1 mm) and an overall textile braid; for a moisture resistant and flame retardant cable the braid is saturated with such a compound, the maker states whether it is flame retardant. Code designation (IEC 60245-1:2003+A1:2007 Annex A, p. 21 to 22): the first numeral is the basic class (0 non-sheathed for fixed wiring, 5 normal duty flexible, 6 heavy duty flexible, 7 special duty, 8 special application), 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. Core colours (IEC 60245-1:2003+A1:2007 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 colour (green-and-yellow and blue in the outer layer) or by number (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. China: GB/T 5013.5-2008 is an identical adoption (IDT) of IEC 60245-5:1994 (SAMR record, checked 2026-11-09; the portal serves no text of it), so its values are this edition's.
