- ZS-600 Pin Post Insulator 24kV 600mm Creepage
Product Overview
A 24 kV pin post porcelain insulator with 600 mm creepage and a 13 kN rated electromechanical failing load. Lightning impulse withstand is 125 kV with 75 kV dry and 55 kV wet power frequency withstand, and the power frequency breakdown voltage is 160 kV. It is the mid-size member of the ZS pin post family, below the 770 mm ZS-770.
Why Buyers Choose This Part
- 600 mm creepage at 24 kV for moderately polluted sites
- 13 kN rated electromechanical failing load
- 125 kV lightning impulse withstand with a 160 kV breakdown voltage
- Pin post mounting keeps the conductor rigid without a string
Where It Is Used
- 24 kV distribution lines through moderately polluted air
- Compact line designs where a suspension string will not fit
- Upgrading a line section that flashes over on standard insulators
- New construction specified at 600 mm creepage
Who It Suits
- Line engineers specifying creepage by pollution class
- Contractors building compact 24 kV lines
- Utilities reducing pollution-related outages
What Goes Wrong Without The Right Part
- Standard pin insulators that cannot hold 24 kV in dirty air
- Pole designs with no room for a longer insulator string
- Lightning trips where impulse withstand is marginal
- Choosing between a 600 mm and 770 mm creepage part without data
How It Is Built
- Rated voltage 24 kV
- 600 mm creepage distance
- 13 kN rated electromechanical failing load
- 125 kV lightning impulse withstand voltage
- 75 kV power frequency dry withstand voltage
- 55 kV power frequency wet withstand voltage
- 160 kV power frequency breakdown voltage

How It Compares
| ZS-770 | The ZS-770 adds 170 mm of creepage and raises the electromechanical rating from 13 kN to 16 kN, with a 190 kV impulse withstand. Specify it only where pollution is severe. |
|---|---|
| ALP22-450 pin insulator | The ALP22-450 is a 22 kV part at 450 mm creepage and 11 kN. The ZS-600 is the step up for 24 kV service with more creepage. |
Before You Order And After It Arrives
- Choose between ZS-600 and ZS-770 from the measured site pollution class
- Keep line pull within the 13 kN electromechanical rating
- Mount on a bracket square to the line
- Inspect shed undersides where deposits accumulate first
