Electrical Line Post Porcelain Insulators

line post insulators have a distinctive design featuring a cylindrical or elongated shape with threaded metal fittings at both ends. the insulator is usually divided into multiple sections or sheds, which are the grooved and ribbed surfaces that increase the effective leakage path and creepage distance. this design helps prevent the accumulation of contaminants like dust, pollution, and moisture, reducing the risk of electrical arcing or flashover.
