Porcelain Line Post insulators are one main type of the highest quality porcelain insulators. They are manufactured from wet process porcelain, giving them the ability to shed water and dirt. This allows for little-to-no maintenance. Line post insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events. Line post insulators were produced with solid core which decides line post insulators are puncture proof type. This not like pin insulators, pin insulators was puntured type.
Horizontal and gain-base line post insulators are often used in applications to avoid the need to install a crossarm on the pole.
The clamp style units include a galvanized metal head which accepts standard trunnion style line clamps.
