Our Professional Answer: A non-metallic (Aramid) pulling sock is an excellent choice for specialized applications, particularly for fiber optic cables. Unlike traditional galvanized steel socks, these are non-conductive, which is a critical safety feature when working around energized lines. They are also lighter and offer high tensile strength without the risk of damaging the delicate outer jacket of fiber optic cables. Their use is ideal in environments like telecommunications, offshore, and other applications where electrical insulation and cable protection are paramount.
