Light rubber cable, used for easy-duty and medium mechanical loads in dry areas. Suitable for household, kitchens, offices and workshops (for inst. tailoring) for smaller electrical devices (washing-machines, vacuum-cleaners, irons, household appliances, soldering sets etc.) and mobile devices operating in heavier conditions, such as light industrial and agricultural machines. Not suitable for permanent outdoor use. Ozone-resistant, allowed contact with oils and greases.
