ANSI 57-1 Porcelain Line Post Insulator | 356 mm Creepage

Product Overview

The existing line-post insulator catalogue image has an ANSI 57-1 column listing 356 mm leakage distance, 165 mm dry arcing distance and 25 kV type application voltage. A separate drawing shows mounting geometry; confirm that drawing and the photographed item against the order model.

Product Details

These are catalogue reference values, not a project voltage rating or evidence of ANSI, IEC, CE or ISO compliance. The chart prints its routine cantilever load as both 1,000 lb and 5 kN, which do not agree as a unit conversion; do not use that row without the original drawing or test record. Check system voltage, pollution conditions, load and mounting before selection.
