Zero value self explosion characteristic, easy to detect faults during inspection
Good stain resistance (depending on specific design)
High mechanic strength
long service life

Mainly used for high-voltage transmission lines, especially for high voltage and ultra-high voltage transmission lines that require high mechanical strength in sections and areas with high pollution levels (depending on the specific design)
