Flashover voltage for pin insulators
Definition of flashover voltage for pin insulators:
Flashover voltage for pin insulators means that a disruptive discharge external to the insulator connects those parts which normally have the operating voltage between them. The term "flashover' used in this part includes a flashover across the insulator surface as well as disruptive discharges by spark over through air adjacent to the insulator.
The lightning impulse voltage which is the low & high voltage insulator withstands dry, under the prescribed conditions of test.

Two types of flashover voltage for pin insulators:
One type flashover voltage for pin insulators is called 50 % dry lightning impulse flashover voltage. The value of the lightning impulse voltage under the prescribed conditions of test has a 50 % probability of producing flashover on the pin type insulator, dry. It is eligible.
Another type flashover voltage for pin insulators is known as wet power-frequency withstands voltage. The power-frequency voltage which the insulator withstands wet, under the prescribed conditions of test.
Flashover voltage, electromechanical failing load, mechanical failing load, puncture voltage, creepage distance and displacements, these consist of technical specifications for pin insulators. To up to clients’ requirements, on one hand we will do mechanical falling load test, on the other hand, we will do test about flashover and creepage distance for pin insulators.
Finally, Orient Company confirms our pin insulators are high-quality and safe products for our customers.
