RZ1MZ1-K LSZH Armoured Cable (0.6/1kV) – XLPE Insulated, Steel Wire Armoured, Low Smoke Zero Halogen Power Cable for Industrial & Public Installations

Introduction

The RZ1MZ1-K LSZH armoured cable is a high-performance low-voltage power cable engineered for demanding industrial and public infrastructure environments. Combining LSZH (Low Smoke Zero Halogen) materials with galvanized steel wire armour (SWA), this cable delivers an optimal balance of fire safety, mechanical protection, and electrical reliability.

It is widely used in oil & gas, petrochemical plants, power distribution networks, and high-occupancy buildings, where both safety and durability are critical.

Cable Construction & Materials

The performance of the RZ1MZ1-K cable is rooted in its carefully engineered multilayer structure:

Conductor

• Class 5 flexible electrolytic copper conductor

• Designed for easier installation and improved flexibility compared to rigid conductors

Insulation

• XLPE (Cross-linked Polyethylene)

• Provides excellent dielectric strength and thermal resistance (up to 90°C operating temperature)

Inner Sheath

• LSZH cross-linked polyolefin

• Enhances fire performance and limits smoke emission

Armour

• Galvanized Steel Wire Armour (SWA)

• Offers strong resistance against:

  • Mechanical impact

  • Rodents

  • Tensile stress and crushing forces

Outer Sheath

• LSZH polyolefin compound

• UV-resistant, flame-retardant, and environmentally safer

Technical Specifications

Available configurations typically range from 1.5 mm² to 240 mm², with multi-core options for flexible installation needs.

Key Applications

RZ1MZ1-K cables are designed for fixed installations in environments requiring both fire safety and mechanical robustness:

• Industrial plants (oil, gas, petrochemical)

• Power distribution networks

• Public buildings (airports, hospitals, tunnels)

• Underground or direct burial installations

• Areas exposed to mechanical stress or rodent risk
