2830 Flashover voltage according to American standard ANSI C29.1 for standard 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.
