3120 Flashover voltage according to American standard ANSI C29.1 for Anti-pollution profile suspension insulator strings not equipped with arcing horns nor grading rings.

According to the American standard, the average value of three tested strings must equal or exceed: - 95% of the guaranteed value given on the data sheet for low frequency dry flashover voltage. - 90% of the guaranteed value given on the data sheet for low frequency wet flashover voltage. - 92% of the guaranteed value given on the data sheet for critical impulse flashover voltage.
