RH5Z1-OL | RH5Z1-2OL Cable

RH5Z1 Cable Description:

RH5Z1 cable is medium voltage aluminium cable with  XLPE insulation  and halogen free outer sheath. Longitudinal aluminium screen provides additional water protection .panish specification Medium Voltage RH5Z1 Cables are available for power distribution projects in voltages 12/20kV and 18/30kV. The cables are manufactured in accordance with HD620 10E2 and UNE 21120:2020

What does RH5Z1 Cable Meaning

RH5Z1 cable range has cross-linked Polyethylene (XLPE) insulation, a halogen-free Polyolefin outer sheath, waterblocking tape over the conductor and longitudinal waterblocking measures (RH5Z1-OL & RH5Z1-2OL). The specification differs ('H5') with an Aluminium tape applied just below the outer sheath, which provides the dual function of moisture blocking and protective screening

R	XLPE (Cross-linked Polyethylene) Insulation
H5	Metallic screen Aluminium
Z1	Polyolefin compound
OL	Longitudinal watertightness over the insulation screen only
