Surge ArresterApplicationProtection of medium/high voltage AC
networks against both, multiple atmospheric and switching
overvoltages as well as Very Fast Transients (VFT). Suitable
for the protection of transformers, transformers in arc furnace
applications, cables, generators, parallel to capacitor banks, and
railway vehicles. Can be used mechanically as support insulator or
as suspension insulator in case of application as line arrester.
For indoor and outdoor installation. KeystoneThe metal-oxide surge
arrester (MOSA) is the most advanced overvoltage protector in the
word. 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' s excellent non-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 conditiona) Ambient air temperature within the range of
-55ºC to +55ºC. b) Altitude not exceeding 2000m. c) Frequency of
the A.C. power supply not less than 48Hz and not exceeding 62Hz. d)
Power frequency voltage applied continuously between the terminals
of the arrester not exceeding its continuous operating voltage. e)
Maximum wind speed not exceeding 35m/s. f) Earthquake intensity not
exceeding 7 degrees. Advantage (XINNENG MOSA)- Low residual voltage
- Long protection distance - High energy input capacity - Stable
U-I characteristic even after multiple strokes - Proof against
ageing - Explosion and shatter-resistant design - Pollution
resistant and UV-stable - Housing resistant to rough handling -
Maintenance fredd - Stable against shock and vibration - High
mechanical resistance Technical PerformanceThe technical
performance of metal-oxide surge arrester is accord with
IEC60099-4, IEEE (ANSI) C62.11 and GB11032. /* January 22,
