aluminum, multi-wire, round, compacted.


aluminum alloy, multi-wire, round, compacted.


made of light-stabilized PEX. Main insulated conductors shall have distinguishing color longitudinal strips of width at least 1mm. Color shall contrast with black. Auxiliary conductors of lightening circuits shall have distinguishing printed marking: "В2", "В2". Insulation of protected wires, neutral carring conductor of self-supporting wiress and auxiliary conductors shall be black, neutral carring conductor of self-supporting wires does not have insulation


insulated main and auxiliary conductors shall be twisted around neutral carring conductor of self-supporting wires. Wires' insulated conductors without current-carrier shall be twisted with each other. Insulated conductors shall be right-twisted in the wire.
