An arcing-horn insertion embedded type polymer line post insulator is provided to prevent a short circuit or a damage of an insulator by blocking an arc during an operation of an arcing-horn. An arcing-horn insertion embedded type polymer line post insulator includes a core unit(210), housing(220), an upper arm unit(240), an arcing-horn(100), and a lower arm unit. The core unit is formed to have a tower shape upwardly. The housing is ejected and formed for a polymer coating and a polymer wing to be formed on a circumference of an outer surface of the core unit. An insert composed of nuts is formed on a lower part of the core unit with an epoxy resin. A molding is formed at the upper arm unit. A high voltage cable is put on an upper part of the core unit. The polymer line post insulator has a multi-layer structure of a cylindrical shape from a lower part to a middle part. The arcing-horn which forms a lock path for protecting the line post insulator is inserted and embedded into the polymer line post insulator. The lower arm unit of a lower part of the arcing-horn is coupled with an insert of the lower part of the core unit by a bolt.
