Porcelain pin insulators introduction:
Zinc Sleeve to prevent pin corrosion
High Leakage and Fog Bowl Pin Types
Two types of standard insulator pins, steel or lead head are available.
ANSI C29.5; ANSI C29.6, IEC60383 and BS137
ANSI 55-1, ANSI 55-2, ANSI 55-3, ANSI 55-4, ANSI 55-5, ANSI 55-6, ANSI 56-1, ANSI 56-2, ANSI 56-3, ANSI 56-4, ANSI 56-5

Porcelain pin insulators are widely used for distribution line and other electric line. With a spindle or pin, the insulator can be smoothly mounted on a supporting structure. These pin type insulators are all single or multi piece designs with porcelain threads, a design which years of field experience has proven to be the best.
