NGK porcelain line post insulator, by a permanently mounted on the metal base glue. For a nominal voltage greater than 1000V, the frequency is not greater than 100Hz, common areas and in the heavy contamination AC power lines in the region and supported insulated conductors.
NGK porcelain line post insulator often used in braced structures whose geometry varies from line to line. A combined loading test to reproduce the complex loading cases in such structures is outside the scope of this standard and it would be very difficult to specify a general test which covers the majority of geometry and loading cases.
Characteristics for NGK porcelain line post insulator:
high mechanical strength
excellent insulation
reliable in operation
simple in maintenance
NGK porcelain line post insulator with insulation and high-voltage transmission and distribution lines to support wire.
