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

  1. Inspect the cable for any damage before installation

  2. Store cables in a clean, dry area, protected from direct sunlight and moisture

  3. Avoid sharp edges during pulling to prevent sheath damage

Bending Radius



Installation Type Minimum Bending Radius
Fixed installation 4 × overall diameter
Mobile/flexing installation 5 × overall diameter

Temperature Limits for Installation

  • Minimum installation temperature: -25°C

  • If ambient temperature is below -25°C, the cable should be stored in a warm environment (>0°C) for at least 24 hours before installation

Termination

  • Use connectors designed for photovoltaic systems

  • Strip back insulation and sheath together – H1Z2Z2-K supports one-step stripping for faster termination

  • Use proper crimping tools – do not use screw connections on Class 5 stranded conductors

  • Follow connector manufacturer's recommended crimping force and tooling

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
