The Zno arrester is mainly used to protect distribution transformer,cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage.
The Zno oxide arrester is the most advanced over-voltage protector in the world.Due to make the resistor disc of core component mainly adopt zine oxide arrester.Compared with the conventional siliconcabide arrester,this presciption of the product improves greatly the volt-Ampere characteris-ics of the resistor disc and increased through-current capability at over-voltage so as to bring a rad Ical-changes for the characteristics of the arresters.
Normal service conditions:
The ambient air temperatures is no higher than +40?棬no lower than -40??.
The altitude above sea level does not exceed 1000-2000m(the altiplanoarea should be indicated when order).
AC system frequency 50Hz or 60Hz.
Industrial frequency voltage brought to bear on arrester for a long time does not exceed arrester sustained operation voltage.
Maximum wind speed does not exceed 35m/s
The earthquake intensity does not exceed 7 degrees.
The fifthy area should be given clear indication.
The technical performance of the product is in confirm to GB 11030-2000,IEC60099-4,IEC37-199/CDV,standard technic requirements.
