Description

64/110kV Copper XLPE Corrugated Aluminum Sheathed Flame Retardant Power Cable

Designed for reliable high-voltage power transmission in utility grids and heavy industrial projects, this 64/110kV copper conductor XLPE insulated power cable combines exceptional electrical performance, robust mechanical protection and superior fire safety. A welded corrugated aluminum sheath provides a 100% moisture barrier, while the flame retardant PE (FR-PE) outer jacket prevents flame propagation in cable tunnels and substations.

Key Features & Benefits

  • Superior Thermal Capacity: XLPE insulation allows a continuous conductor operating temperature of 90°C and a short-circuit emergency temperature of 250°C.
  • 100% Waterproof & Mechanical Shielding: The continuous welded corrugated aluminum sheath acts as an impermeable radial moisture barrier, preventing water treeing while offering excellent anti-crush performance.
  • Enhanced Fire Safety: A specialized flame retardant PE (FR-PE) jacket prevents flame propagation in tunnels, substations and densely populated industrial areas.
  • Corrosion & Pest Resistance: The robust outer jacket resists soil acids, alkalis, termites and mechanical abrasion during burial.
  • Optimized Flexibility: The corrugated aluminum layer improves the bending radius versus smooth aluminum sleeves, simplifying installation in tight spaces.

Frequently Asked Questions

Q1: What are the main benefits of a welded corrugated aluminum sheath over a lead sheath?
A: Welded corrugated aluminum sheathing provides excellent mechanical crush resistance and acts as a 100% moisture barrier, preventing water treeing in the XLPE insulation. Compared with traditional lead sheaths it is much lighter, reducing transport and installation costs, offers better fatigue resistance against thermal cycling, and is more environmentally friendly.

Q2: Does this 64/110kV cable comply with international IEC standards?
A: Yes. The cable is manufactured and tested in accordance with IEC 62067 and IEC 60228. For fire safety it complies with IEC 60332-1-2 and IEC 60332-3. Complete type test reports from audited third-party laboratories are available on request.

Q3: What is the minimum bending radius during installation?
A: The minimum bending radius is 20 times the overall cable outer diameter (20 x D) during installation, and 15 times the outer diameter (15 x D) when permanently fixed in position.

Q4: What is the maximum continuous conductor operating temperature?
A: The XLPE insulation supports a continuous conductor temperature of 90°C and a short-circuit emergency temperature of 250°C (max 5 s).

Q5: What packaging and logistics support do you provide for EPC projects?
A: Cables are supplied on heavy-duty steel-wooden or full steel drums treated for international maritime transit. We support FOB, CIF and DDU/DDP terms and welcome third-party factory acceptance tests from SGS, Intertek or Bureau Veritas.
