IEC 60277-6:2001 pdf free download.Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 v-Part 6: Lift cables and cables for flexible connections.

Values in parentheses are the non-preferred types.

The conductors shall comply with the requirements given in lEG 60228 for class 5 conductors.

The conductors of the cores in the side position may consist of copper wires and steel wires. The nominal geometric cross-sectional area of these conductors shall be equal to that of the other conductors and the maximum resistance shall be not more than twice the maximum resistance of a copper conductor of the same nominal cross-sectional area.

3.3.2 InsulatIon

The insulation shall be polyvinyl chloride compound of type PVC/D applied around each conductor.

The insulation thickness shall comply with the specified value given in table 4, column 2.

The insulation resistance shall be not less than the value given in table 4. column 3.

3.3.3 Arrangements of cores and strain-bearing members, if any

The cores shall be laid parallel. It is permitted, however, that two, three, four o five cores may be laid in groups: in such

cases, a tearing thread may be inserted inside each group. It shall be possible to separate the cores without damage to the

insulation.
