metal oxide gapless types of lightning surge arrester
Product Description:
Protection of medium/high voltage AC networks againt both, multiple atmospheric and switching overvoltages as well as Very Fast Transients(VFT).Suitable for the protection of transformers,transformers in arc furnace application,cables,generators,parallel to capacitor banks,and railway vehicles.Metal Oxide Surge Arrester can be used mechanically as support insulator or as suspension insulator in case of application as line arrester for indoor and outdoor installation.
Keystone:
The Metal-Oxide Surge Arrester(MOSA)is the most advanced
overvoltage protector in the world. Due to make the varistor of
core component mainly adopt MOSA. Compared with the conventional
silicone carbide arrester,this prescription of the product
improves greatly the Voltage-Current(U-I) characteristic of the
metal-oxide varistor and increased through-current capability at
over-voltage so as to bring a radical-changes for the
characteristic of the MOSA.
Under the circumstance of normal operating voltage,the current
through the MOSA just on microampere degree.When suffered from
overvoltage,the MOSA'sexcellent none-linear characteristic will
make the current through the MOSA increase to several thousand
ampere,while the MOSA will be under the circulating state and
release overvoltage energy so as to protecting the power
transmission equipments against the damage caused by the
overvoltage.
Usual Service Condition:
a)Ambient air temperature within the range of
**5℃to**5℃.
b)Altitude not exceeding ***0m.
c)Frequency of the A.C.power supply not less than *8Hz and not
exceeding *2Hz.
d)Power frequency voltage applied continuously between the
terminals of the arrester not exceeding its continuous operating
voltage.
e)Maximun wind speed not exceeding *5m/s.
f)Earthquake intensity not exceeding 7 degrees.
Advantage (SWITOL MOSA):
a)Low residual voltage
b)Long protection distance
c)High energy capacity
d)Stable U-I characteristic even after multiple
strokes
e)Proof against ageing
f)Explosion and shatter-resistant design
g)Pollution resisitant and UV-stable
h)Housing resistant to rough handing
i)Stable against shock and vibration
j)High mechanical resistance
Technical Performance:
The technical performance of metal-oxide surge arrester is according to IEC******4,IEEE(ANSI)C*2.*1 and GB****2
