FAQ
Q. Can These cables be used for DC systems?
A. Yes, but DC-rated XLPE insulation is required to prevent space charge accumulation. Standard AC cables may degrade under long-term DC voltage.
Q. What is the typical lifespan of these cables in underground installations?
A. 30+ years with proper installation (e.g., sand bedding, moisture-proofing). PVC sheath resists chemical corrosion in soil.
Q. Are these cables suitable for offshore wind farms?
A. Yes, but corrosion-resistant outer layers (e.g., PE instead of PVC) are recommended for saltwater environments.
Q.. What’s the weight advantage of alumium cable vs. copper cables?
A. A 150mm² YJLHV62 weighs ~2.5kg/m, while a copper equivalent weighs ~4kg/m, reducing structural load.
Q. Is this cable suitable for high-vibration environments?
A. Yes. Steel armor absorbs mechanical stress, but vibration dampers are advised for long-term use.
