ANSI 55-3 pin type insulator thread type:
1” porcelain thread type
Assembled spindle or pin for ANSI 55-3 pin type insulator: should fit with 1” lead head spindle
Neck and groove information:
ANSI 55-3 is “C” neck.
Top-wire groove and side-wire grooves shall seat a mandrel with a diameter of 1-1/16 inches.
If high-resistance coatings are applied to the high voltage insulator, such coatings shall be considered as effective leakage surfaces, and the distance over them shall be included in the leakage distance.
