0.6/1kV RZ1MZ1-K Cable

What is RZ1MZ1-K Cable?

RZ1MZ1-K Cable is a 0.6/1kV Class 5 flexible copper conductor XLPE insulated SWA power cable complying with UNE 21123-4, EN 60228, and HD 603 standards.

Designed for low-voltage power networks and auxiliary fixed wiring where installation flexibility and fire safety are required, it features Class 5 fine-wire stranded copper conductors, XLPE insulation, an LSZH bedding layer, Galvanized Steel Wire Armour (SWA), and a distinctive green LSZH outer sheath. Under fire conditions, it delivers robust mechanical impact protection alongside minimal smoke density and zero corrosive toxic gas emissions, safeguarding human life and critical electrical infrastructure.

RZ1MZ1-K Cable Construction

• Conductor: Class 5 flexible stranded copper conductor
• Insulation: XLPE (Cross-Linked Polyethylene)
• Bedding Layer: LSZH (Low Smoke Zero Halogen)
• Armour: Galvanized steel wires (SWA)
• Outer Sheath: LSZH (Low Smoke Zero Halogen)
• Core Identification: 1 Core: Black; 2 Core: Blue, Brown; 3 Core: Grey, Black, Brown (or Green/Yellow, Blue, Brown with earth); 4 Core: Blue, Brown, Black, Grey (or Green/Yellow, Brown, Black, Grey with earth); 5 Core: Green/Yellow, Blue, Brown, Black, Grey
• Outer Sheath Colour: Green

Applications

RZ1MZ1-K 0.6/1kV Cable is engineered for power networks, underground installations, cable ducting, and fixed indoor or outdoor wiring where physical impact protection and LSZH safety compliance are mandated. Key application environments include:

• Public buildings, transit systems, tunnels, and commercial complexes
• Direct underground burial and subterranean cable ducting networks
• Tight-bend or complex wiring routes requiring Class 5 flexible conductors
• Industrial power networks requiring mechanical protection against physical stress

Frequently Asked Questions

Q: What is the main structural advantage of RZ1MZ1-K cable over standard rigid armoured cables?
A: RZ1MZ1-K utilizes Class 5 fine-wire flexible copper conductors instead of Class 2 rigid conductors, making cable pulling and installation significantly easier in tight or complex conduits.

Q: What does LSZH mean in RZ1MZ1-K cables?
A: LSZH stands for Low Smoke Zero Halogen. In fire conditions, the LSZH bedding and outer sheath emit minimal smoke and zero toxic halogen gases, protecting human lives and electronic equipment.

Q: Can RZ1MZ1-K armoured cable be directly installed underground?
A: Yes, the Galvanized Steel Wire Armour (SWA) layer provides mechanical strength against physical crushing, making it suitable for direct underground burial and ducting.

Q: What payment terms does Huadong Cable Group accept for international orders?
A: We accept Telegraphic Transfer (T/T) and Irrevocable Letter of Credit (L/C) at sight for international B2B transactions.
