TOXFREE® ZH RZ1MZ1-K (AS), the halogen-free ATEX installation cable

TOXFREE® ZH RZ1MZ1-K (AS) cable is a cable specially designed to obtain maximum protection while still transmitting energy in installations with a high risk of fire and explosion (ATEX). It is a non-fire propagation cable that complies with the IEC 60502-1 and UNE 21123-4 reference standards.

DESIGN:

1 – Flexible copper conductor (class 5).

2 – Cross-linked polyethylene insulation (XLPE).

3 – Flexible, halogen-free, flame-retardant polyolefin outer sheath with low emission of smoke and corrosive gases in case of fire.

DESIGNED ACCORDING TO THE REFERENCE STANDARDS

This cable has been designed according to IEC 60502-1 and UNE 21123-4 reference standards. It has an armour with galvanised steel wires placed in a helix on the seat which, like the outer sheath, is made of fireproof polyolefin, green in colour, halogen-free. This type of cable is manufactured in single core and multicore versions. In single-core cables, aluminium wires are used to reduce losses due to induced currents in the armour.
