Appliation:
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.
Keystone:
The zinc 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 siliconcarbide arrester, this presciption of the product improves greatly the volt-Ampere charateristics of the resistor disc and increased through-current capability at over-voltage so as to bring a radical changes for the characteristics of the arresters.
Under the circumstance of normal operating voltage, the current through the arrester is just on micro ampere degree. When suffered from over-voltage, the arrester’s excellent nonlinear characteristics will make the current through the arrester increase to several thousand amperes, while the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the damage caused by the over-voltage.
Normal service conditions:
The ambient air temperarture is no higher than +40 degree. no lower than -40 degree.
The altitude above sea level does not exceed 1000~2000m (the altiplanoarea should be indicated when order).
AC system frequency 50~60HZ.
Industrial frequency voltage brought to bear on arrester for a long time does not exceed arrester’s sustained operation voltage.
Maximum wind speed not exceed 35m/s.
The earthquake intensity does not exceed 7 degrees.
The filthy area should be given clear indication.
Technical performance:
The technical performance of the product is in confirm to IEC60099-4, IEC37-199/CDV, standard technical requirements.
