[Current]Electric cables - Reeling and trailing - For mining and general use (other than underground coal mining)
Specifies the requirements for two classes of multicore elastomer insulated and sheathed flexible reeling and trailing cables for surface mining, underground mining (other than coal mining) and general use, where movable plant requires electricity supply at system voltages from 1.1/1.1 kV up to and including 33/33 kV.
