2 these ratings are not applicable to cables wound on reeling drums or covered over or coiled up.
Flexible cables are used for appliances because appliances usually get moved around a lot and the inflexibility of a fixed cable either 1 5mm or 2 5mm would soon crack the cable causing faults and potentially the risk of shock and injury.
