When should XLPE insulation be preferred over PE or PVC?

XLPE (Cross-linked Polyethylene): Offers superior thermal stability (up to 90°C), lower dielectric constant, and better moisture resistance. It is the preferred choice for long-distance signal transmission where signal attenuation must be minimized.

PE (Polyethylene): Excellent for high-frequency signal transmission but has lower temperature limits.

PVC: Cost-effective and flexible, but typically limited to 70°C and less suitable for critical high-speed data.
