Description

Application scope
  • Used for power supply to distribution networks and industrial equipment installations.


Notes
  • Materials: conductor made of high-purity oxygen-free copper; insulation: cross-linked polyethylene (XLPE); outer sheath: flame-retardant polyvinyl chloride (PVC).
  • Standards: GB/T12706.1-2020; documentation also references IEC 60502-1.


Operating characteristics
  • Long-term operating temperature: ≤ 90°C.
  • Short-circuit temperature tolerance: up to 250°C for 5 seconds.
  • Cable laying ambient temperature: ≥ 0°C.
  • Bending radius: see documentation (examples: flexible cable D < 25 mm ≥ 4D; D ≥ 25 mm ≥ 6D; other core configurations may require 12D–15D).
  • Typical structure: conductor / XLPE insulation / inner bedding / steel tape armour / outer PVC sheath.
  • Sheath colour options: red, yellow, green, blue or black for phase identification.
  • Environmental and chemical resistance: resistance to water, acids and oils; suitable for ducts, trenches and embedded installations when installed according to relevant codes.

Additional technical notes
  • Typical use: fixed installations in power distribution networks at AC rated voltage 0.6/1 kV (substations to end-user equipment in commercial, industrial and infrastructure projects).
  • XLPE insulation provides improved thermal endurance, mechanical strength and resistance to ageing compared with conventional thermoplastic insulations.
  • Oxygen-free copper conductor reduces resistive losses and improves current-carrying efficiency.
  • PVC outer sheath offers flame-retardant properties and protection against mechanical damage, abrasion, oil and chemicals when correctly applied.
  • Suitable installation environments: cable ducts, trenches, embedded in concrete or other protected conduits when installed according to relevant codes and practices.
