Cable with aluminium core, with insulation and sheath of polyvinylchloride plasticate, unarmoured. Designed for transmission and distribution of electrical energy in stationary electrical installations. The cable is designed for operation in electric networks of alternating voltage with earthed or insulated neutral, for operation at ambient temperature from minus 50?? to plus 50?? and relative air humidity up to 98% at temperature up to 35??. For laying of single cable lines in cable constructions and premises, in case of group laying it is obligatory to use fire protection means.
