Product Description

HL-YH5W(YH10W)-6kV With  Pmc  Insulating Bracket
Application     
Protection of medium/high voltage AC networks against both, multiple atmospheric and switching  over voltages  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.
Keystone  
    The metal-oxide surge arrester (MOSA) is the most advanced over voltage protector in the word.Due to make the varistor of core com-ponent 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 over voltage,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 over voltage energy so as to protecting the power transmission  equipments against the damage caused by the over voltage.

Usual service condition                                                                          
a) Ambient air temperature within the range of -55ºC to +50ºC.
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.
