Product DescriptionZinc oxide arrester is suitable for AC 220kV and
below power generation, transmission, substation, and distribution
systems. It is used to limit the amplitude of lightning and
overvoltage in the system to a specified level. It is the basic
equipment for the insulation coordination of the entire system. It
is the best lightning protection element in the integrated and
modularized medium and high voltage power transmission and
transformation equipment.The power station type zinc oxide arrester
is a lightning arrester with good protection performance. Using the
good nonlinear volt-ampere characteristics of zinc oxide, the
current flowing through the arrester is extremely small (microamp
or milliamp level) under normal working voltage; when overvoltage
acts, the resistance drops sharply, discharging the energy of the
overvoltage, achieve protective effect. The difference between this
arrester and the traditional arrester is that it has no discharge
gap, and uses the nonlinear characteristics of zinc oxide to play
the role of leakage and interruption.Model DescriptionProduct

production standard of the product is GB11032-2000 (eqv
IEC60099-4:1991) "AC No-gap Metal Oxide Surge Arrester",
JB/8952-2005 "Composite Jacket No-gap Metal Oxide Surge Arrester
for AC System"1. The arrester should be stored in a clean and dry
room before installation and use. Must not be corroded by corrosive
gases or liquids.2. Before the arrester is put into operation, a
preventive test should be carried out. After being put into
operation, it should also be regularly (10KV and below arrester
once every 5 years, 35KV and above arrester once every 2 years)Do
the following test and compare with the data before operation with
reference to the attached table:a. Measure the insulation
resistance of the arresterb. Measure the DC 1mA voltage of the
arresterc. Measure the leakage current of 0.75 times DC 1mAProduct
