Pin type porcelain insulators of one piece or multipiece construction are widely used in low cost distribution lines. Fog Bowl designs offer high protected leakage areas.

Pin type porcelain insulators specifications:
Rated Voltage: 10-36KV
Pin insulator spindles include short spindle and long spindle.
High Leakage and Fog Bowl Pin Types
No cement growth problem - Stable mechanical performance
Acceptance Criteria for T&M Test
Uniform quality by continuous firing and production control
Accurate assembling without stress concentration
Porcelain pin type insulator is mounted rigidly on a supporting structure by an insulator pin or insulator spindle.

Multipiece construction makes these pin type porcelain insulators less vulnerable to damage as with one shell broken a multipeice insulator can normally withstand the line voltage for a considerable time without difficulty. Low voltage pin types are manufactured and tested to the requirements of ANSI Standard C29.5, high voltage porcelain pin insulators to ANSI Standard C29.6, and special designs for use in areas of high contamination.

The design of these pin type porcelain insulators is affected decisively by the requirements of our customers and depends strongly on the environmental conditions of their future location.
