Product Description

ANSI 57-3 line post insulator for transmission line features:
1. Applications: Long-span rural construction requires relatively wide phase spacing on the supporting structure to provide adequate, mid-span conductor clearances under extreme conditions.
2. Other porcelain tie top line post insulators: ANSI 57-3, ANSI 57-2, ANSI 57-4, ANSI 57-5, ANSI 57-6
3. ANSI 57-3 line post insulator for transmission line : Vertical & Horizontal Mounting Tie-Top Type with Stud Base, F neck
4. Easier stock inventory-separable long or short studs for wood and steel crossarms are easily installed in the field.
5. ANSI 57-3 line post insulator for transmission line is used the same ways as distribution ceramic pin insulator, but ceramic line post insulator is non-puncturable design.
6. ANSI 57-3 line post insulator for transmission line is 100% puncture-proof solid core insulators.
7. ANSI 57-3 line post insulator for transmission line Standards: ANSI C29.1-1988, ASTM A153-82, ASTM A153-82
