Common underground cables use which insulation material according to the material?

Explanation:
Common underground cables need insulation that can withstand moisture, soil chemicals, and long-term burial while maintaining electrical isolation. ALPETH is the insulation material most commonly specified for this use because it offers strong dielectric properties, moisture resistance, and compatibility with standard extrusion processes, delivering reliable buried performance at a reasonable cost. The other materials referenced are not the standard underground insulation in typical OSP practice, as they either refer to different cable constructions or are not widely used for buried installations.
