Advantages:
Environmentally safe: Low-smoke, halogen-free design minimizes smoke and releases no corrosive gases in case of fire, making it suitable for densely populated areas.
Strong weather resistance: Polyolefin sheath is resistant to UV radiation, ozone, and moisture, making it suitable for long-term outdoor exposure environments.
Stable electrical performance: Cross-linked polyethylene insulation offers high dielectric strength, resistance to partial discharge, and high long-term operational reliability.
Lightweight and flexible: Compact structure with good bending performance facilitates transportation and installation on complex paths.
Chemical corrosion resistance: The sheath has strong resistance to chemical media such as acids and alkalis, making it adaptable to corrosive environments.

Application Scope:
Mainly used for fixed power transmission in urban grids, rural grids, outdoor distribution lines, direct burial installations, tunnels, underwater installations, and large-scale projects sensitive to costs.

Special Notes:
Aluminum conductor connections require fittings and techniques; the PE sheath offers weak mechanical protection, and armored models (e.g., YJLY23) are recommended for applications prone to external damage. Its good low-temperature resistance facilitates construction in cold regions; not recommended for indoor dense installations with high flame-retardant requirements.
