Fixed installation
Engineered for fixed medium-voltage distribution in cable trenches, ducts, trays and indoor substations.
Product
ARG7H1OR 12/20 (24) kV medium-voltage three-core distribution cable featuring compact Class 2 aluminium conductors, triple-extruded G7 HEPR dielectric, per-phase H1 copper tape screens and a flame-retardant red Rz PVC outer sheath.
Typical values for this cable type, based on CEI UNEL 35755 / IEC 60502-2 — confirmed in the datasheet and quotation for your order.
Application fit
ARG7H1OR 12/20 (24) kV medium-voltage three-core distribution cable featuring compact Class 2 aluminium conductors, triple-extruded G7 HEPR dielectric, per-phase H1 copper tape screens and a flame-retardant red Rz PVC outer sheath.
Engineered for fixed medium-voltage distribution in cable trenches, ducts, trays and indoor substations.
Suitable for primary 12/20 kV industrial plant feeders and transformer interconnections.
Suitable for fixed tunnel brackets where PVC flame-retardant category per IEC 60332-1-2 is permitted.
Class 2 compact aluminium conductors are for static installation only; not for reeling drums.
