scope:

Applies to multicore and multipair rigid and flexible conductor cables for fixed installations having a rated voltage up to 1 kV and operating at a voltage above 80 V rmx. The insulation and sheath may be either thermoplastic or thermosetting, halogenated or halogen free. The cables are mainly intended for use in power generating plants and substations and some for direct burial in conjunction with utility operations. Cables may have specific fire performance requirements. Cables designed to be installed within the containment area of nuclear power plants (LOCA cables), or cables specifically designed to be radiation resistant are not included in this standard.
