4 VOLTAGE IWSIGNATJON

Due to common usage in the mining industry, cables in this Standard have voltages designated using ‘phase voltage’phase

voltage’. However, although the cables specified br use with a.c. in this Standard are suitable in non-elTectively earthed systems they are not intended for continuous operation with one phase earthed.

The voltage designation takes into consideration the fact that the system voltage may vary up to 9,1 percent from the designated

voltage.

5 DESIGNATION AND APPLICATION

Cables are designated by means of a type number. The type number incorporates reference to the voltage. e.g. ‘l’ype 209.3

identifies I’ype 209 rated at 3.3/3.3 kV.

Types of cables and their applications are listed in Table I.
