Product DescriptionSurge arrester is a kind of overvoltage
protector, which is mainly used to protect various electrical
equipment (transformers, switches, capacitors, wave arresters,
transformers, generators, motors, power cables, etc.in power
systems, railway electrification systems, and communication
systems. ) is protected from atmospheric overvoltage, operating
overvoltage and power frequency transient overvoltage, etc., and is
the basis for the insulation coordination of power systems.The core
element (resistor sheet) of the metal oxide arrester adopts an
advanced formula based on zinc oxide, which has very excellent
nonlinear (volt-ampere) characteristics, that is, under normal
operating voltage, the current passing through is only microampere
level. , When subjected to overvoltage, the passing current reaches
thousands of amperes instantaneously, making the arrester in a
conducting state and releasing overvoltage energy, thereby
effectively limiting the damage of overvoltage to power
transmission and transformation equipment.The traditional SiC
arrester has the disadvantages of high steep wave discharge voltage
caused by steep wave discharge delay, and high operating wave
discharge voltage due to large operating wave discharge dispersion.
The zinc oxide arrester has the advantages of good steep wave
response characteristics, no delay to the steep wave voltage, low
operating residual voltage, and no discharge dispersion. The
protection margin of steep waves and operating waves is greatly
improved, and in terms of insulation coordination, the protection
margins of steep waves, lightning waves and operating waves can be
nearly the same, thus providing the best protection for power
equipment..The composite jacket metal oxide arrester adopts the
overall injection molding and two-end encapsulation process, with
good sealing performance, excellent explosion-proof performance,
pollution resistance, no cleaning, and can reduce the occurrence of
wet flash in foggy weather, electric corrosion resistance,
anti-aging, small size, light weight , easy to install and
maintain. It is a replacement product of porcelain sleeve
arrester.Model DescriptionProduct technical parameters and

implementation standards and user noticesThe 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
