This part of BOS 589 covers requirements for packaging and marking, for single-core and multicore extruded solid dielectric insulated cables of rated operating voltage (U0/ U) in the range 300/500 V to 1 900/3 300 V, for use in fixed installations, as covered by BOS 589-2 and SANS 1507-3 to SANS 1507-6.
Specific requirements are given for a number of types of cables in common use. The types are as follows:
a) single-core and multicore cables, armoured and unarmoured;
b) multicore flat cables with and without an earth continuity conductor;
c) multicore round cables with aluminium / PVC laminate and an earth continuity conductor;
d) cables with concentric conductors;
e) cables with split concentric neutral and earth conductors;
f) panel/cubicle cables, excluding flexible cables and cords; and
g) insulated earth conductors.
This specification also covers cables that reduce the overall risk associated with fires.
