33kv insulators normally include pin insulator, pin post insulator, line post insulator, suspension insulator and post insulator used for 33kv power lines.

33kV pin insulator

33kv insulators shall be in accordance with the latest editions of the standards specified below and amendments thereof.
◆ ANSI C29.1 -Test methods for electrical power insulators.
◆ ANSI C29.5 and ANSI C29.6) -Wet process porcelain insulators – porcelain pin insulator
◆ ANSI C29.2 – pin insulator manufacturing way and technical parameters
◆ ANSI C29.7 – line post insulator properties and insulator tests
◆ ANSI C29.9 – the methods of post insulators

If insulator manufacturers or insulator trading companies transport the 33kv insulators, the 33kv insulators shall be marked with the followings.
◆ Name or Trademark of the Manufacturer or trading company
◆ Rated voltage in kv
◆ The minimum failing load in kN
◆ The year of manufacture

These markings shall be legible, indelible and weatherproof. 33kv insulators are normally used on transmission and distribution lines, such as used on poles lines for insulating and supporting wires.
