What are the core differences between XLPE and PVC insulated cables in industrial applications?

XLPE (cross-linked polyethylene) and PVC (polyvinyl chloride) cables differ significantly in performance: XLPE offers higher temperature resistance (90-150°C vs. PVC's 70-90°C), superior chemical resistance, and lower dielectric loss, making it ideal for high-voltage (up to 35kV) and high-temperature industrial systems. PVC, while more cost-effective and easier to process, has lower thermal stability and releases toxic halogens when burned, limiting its use in public or environmentally sensitive areas.
