Medium Voltage X-VOLT RHZ1 (AS) AL/OL/2OL Cable

It is a cable for fixed installations, adequate for energy transport and distribution in Low Voltage networks. The (AS) indication certifies that it is a high security, halogen-free, flame-retardant and fire-retardant cable.

The Low Voltage X-VOLT RHZ1 (AS) AL/OL / 2OL cable has been designed according to the construction norms UNE-HD 620-5-E (type 5E-5) and IEC 60502-2. Its AENOR certification attests to the exhaustive fulfilment of all requirements demanded by regulation UNE- HD 620.

Cable design

The conductor is made of electrolytic aluminium, class 2, insulated with reticulated polyethylene (XLPE), reticulated in dry nitrogen gas, with a shield of copper wiring and a cross-wound loop of copper tape and, in the versions of the –OL and -2OL type cables, a hygroscopic tape that completely covers the shield.

Technical characteristics

For the nominal voltages 6/10 kV, 8.7/15 kV, 12/20 kV and 18/30 kV the maximum conductor temperature is 90ºC, and the maximum short-circuit temperature is 250 ºC (for a maximum duration of five seconds). This cable allows for a bending radius of fifteen times the outer diameter. Due to its excellent mechanical properties, the RHZ1 aluminium cable, fabricated by Top Cable, is ideal for interior, exterior or underground installations.

Fireproof polyolefin sheath

The outer sheath of the X-VOLT RHZ1 (AS) AL cable is made of fireproof polyolefin, halogen-free and black with two green stripes.

Certifications and type-approval

The X-VOLT RHZ1 (AS) AL cable is approved by Spanish Association for Standardisation and Certification (AENOR) and certified by the electric companies Endesa and Unión Fenosa.

Other available versions

There are other available versions in the X-VOLT family: this cable is likewise manufactured for applications that require a flame-resistant cable (X-VOLT RHZ1 AL/ OL / 2OL (S) ) for voltages of 6/10 kV, 8.7/15 kV, 12/20 kV and 18/30 kV. Likewise, the X-VOLT cable can be designed from a copper conductor.
