RH5Z1 Cables

Spanish 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 and form part of our extended European Medium Voltage cable portfolio.

As per the standard HD620 10E2 and meeting requirements of cable type 10 E-6, our RH5Z1 cables have Aluminium conductors - Copper conductors are only permissible for these cables in the (AS) variants and in the larger cross-sectional area sizes of 500mm2 and 630mm2 (HD620 10E-8).

RH5Z1 Cable Construction

Similar to the RHZ1 Cables, the RH5Z1 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
2OL	Longitudinal watertightness in conductor and over insulation screen

 

 

RH5Z1 Cable Sheath Material

As is the case with the RHZ1 cables, the Polyolefin sheathing material on the RH5Z1-OL & RH5Z1-2OL cables is a Polyethylene compound (PO DMZ1)  - naturally halogen free, but not 'Low Smoke Zero Halogen'. It is compliant with IEC 60754-1/2. Where required, it can also be produced to be flame retardant (using PO compound DMZ2) to IEC 60332-1-2 and compliant to CPR Euroclassification Eca (S) and also flame retardant and compliant with CPR Euroclassification Cca s1b, d2, a2 (AS).  

Specification RH5Z1-OL / RH5Z1-2OL - Cable Datasheets

In accordance with the standard, these cables are not available in every cross-sectional area size (should other sizes be required, these can be made 'generally in accordance'). The conductors sizes from 50mm2 to 630mm2 are provided on the datasheets linked below. These datasheets also contain electrical data to support specification and selection.
