What type of insulator used at dead ends and on straight lines as suspension type for voltages 3.3 kV and above?
What type of insulator used at dead ends and on straight lines as suspension type for voltages 3.3 kV and above? Correct Answer Strain insulators
- Strain and shackle insulators are used at dead ends in low voltage distribution lines (less than 11 kV).
- Pin insulators used in electric distribution systems up to 33 kV voltage level.
- Beyond operating voltage of 33kV, pin insulators become too bulky and uneconomical
- Suspension insulators are used for higher than 33 kV voltage levels
