Red colour metal oxide surge arrester with popular style

 Application

    The ZnO is mainly used to protect distribution transformer, cable connector and
electric equipment from being damaged by lighting impulse voltage and operated over-voltage.

Keystone
     The zinc arresteris the most advanced over-voltage protector in the world,Due to make teh
risistor disc of core component mainly adopt zine oxide arrester,Compared with the conventional
siliconcarbide arrester,this predciption 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 lcal-changes
for the characteristics of the arresters.

Normal service condtions
The ambient air temperatures is no higher than +40℃,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 arrest-er'
ssustained operation voltage.
Maximum wind speed does not exceed 35m/s.
The earthquake intensity does not exceed 7 degrees.
The filthy area should be given clear indicateon.

Technical Standard
      The technical performance of the prodect is in conform to GB11032-200,IEC60099-4,IEC37-199/CDV,
standard technic requirements.
