- Q2: How do ampacity and temperature ratings compare to copper wire?
- A: For the same gauge, ampacity is ~80% of copper, but weight savings and cost efficiency are significant; heat rating usually up to 90°C (UL 44 / ICEA).
- Q3: What testing/inspection does each batch undergo?
- A: Resistance (Ω/km), tensile strength, elongation, diameter uniformity, insulation integrity, and environmental simulation as per ISO 9001 and UL requirements.
- Q4: What insulation or sheath options are available?
- A: XLPE (cross-linked polyethylene), PE (polyethylene), and PVC (polyvinyl chloride) with UV/fire resistance per client/project needs.
- Q5: What installation codes must be followed?
- A: NEC (US), IEC 60228, and regional utility regulations mandate correct lugs/joints and torque settings for aluminum conductors to avoid hot-spots.
- Q6: What is the typical lifespan of aluminum electrical wire underground?
- A: Properly installed 4 0 aluminum wire, especially insulated types like 6 3 aluminum underground wire, lasts 30 years or more thanks to corrosion resistance and anti-aging treatments.
- Q7: Is copper clad aluminum wire for sale a safe alternative?
- A: CCA wire is safe when applied within ampacity limits and installed to code, but for high-criticality/long-term applications, pure aluminum or copper is preferable due to mechanical strength and certification scope.
