ANSI 57-14 porcelain line post insulator,vertical line post insulator

ANSI 57-14 porcelain line post insulator is an insulator of generally columnar shape, having means for direct and rigid mounting. Vertical line post insulator is fixed vertically on crossarms by spindles.

With the replaceable feature by pin insulators and non-puncturable structure, porcelain line post insulators are mainly used to insulate and support conductors. Orient manufacture vertical line post insulator in accordance with the standards of GB, IEC, ANSI and BS can as well as customers' special requirements.

ANSI 57-14 porcelain line post insulator specifications:
Line Post Insulators are designed to be used on long rural lines to great reliability and durability free of maintenance. The vertical line post insulator has good water-repellent, aging-proof, anti current leakage and anti electric corrosion performance. It also has high resistance to bending and erosion with high mechanical strength. Furthermore, the light weight and the size make it easy for installation.
