Construction Details
| Layer | Material | Specification | Function |
|---|---|---|---|
| Conductor | Tinned copper | Class 5 (flexible) per IEC 60228 – finely stranded | High flexibility, corrosion resistance, excellent conductivity |
| Insulation | Cross-linked halogen-free flame retardant (XL-HFFR) | Electron beam cross-linked | High thermal rating (120°C), electrical isolation, halogen-free |
| Outer Sheath | Cross-linked halogen-free flame retardant (XL-HFFR) | Electron beam cross-linked, UV stabilized | Mechanical protection, UV resistance, weather resistance |
Double-Layer Sheath Design
The H1Z2Z2-K cable features a double-layer sheath construction:
Insulation layer – Provides electrical isolation and thermal protection
Separate outer sheath – Offers enhanced mechanical protection and UV resistance
This design is achieved through electron beam (E-beam) cross-linking using advanced equipment such as the Russian radiation cross-linking particle accelerator. This process significantly improves the cable's thermal, mechanical, and chemical properties, making it exceptionally resistant to pressure, bending, tension, impact, and temperature extremes.

Installation Guidelines
Preparation
Inspect the cable for any damage before installation
Store cables in a clean, dry area, protected from direct sunlight and moisture
Avoid sharp edges during pulling to prevent sheath damage
Bending Radius
| Installation Type | Minimum Bending Radius |
|---|---|
| Fixed installation | 4 × overall diameter |

Cable Routing
Avoid sharp bends – maintain minimum bending radius
Protect from mechanical damage – use conduit or cable trays in high-traffic areas
Provide adequate support – prevent sagging and stress on connections
Separate from AC cables – avoid electromagnetic interference where possible
