RG7H1R Description
Single-core cables, insulated with HEPR rubber of G7 quality, under PVC sheath.. Conductor: class 2, compact stranded wire, plain copper
. Semiconductor layer: extruded (only cables Uo/U ≥ 6/10 kV)
. Insulation: HEPR rubber, G7 quality, Pb free
. Semiconductor layer: extruded, cold stripping (only cables Uo/U ≥ 6/10 kV)
. Screen: plain copper wires with helically wound tape . Sheath: PVC based compound, Rz quality
. Colour: red
N.B. The cable can be built in the three-pole version with helically wound cores. In this case, the initials becomes RG7H1RX, followed by rated voltage.
