12 кВ Оксид цинка Молния перенапряжения

Key words : 12KV Zinc Oxide Lightning Arrester,Metal Oxide Surge Arrester and so on We are the OEM manufacture.Founded in 1999,have 10 years experience in arrester,metal oxide surge arresters ,computer reactive power compensation devices,fall-type fuse,isolating switch,high voltage composite insulators,such as lightning protection products Lightningarrester is to protect electrical equipment in power system from damageof over voltage and high voltage. The product characteristic: Smaller in size,Light in weight,High withstand collision,Flexible installation, Particularly suitable for use in the switch cabinSpecial structure, the overall compression molding, no air gap, high sealing performance, moisture-proof explosion-prooflarge creepage distance , good hydrophobic, strong resistance to incompetence, stable performance and reduce operation and maintenanceHigh performance zinc oxide varistor, high-capacity, low-leakageReal with DC reference voltage, square-wave-pass flow capacity and high current tolerance is higher than the national standard The technology parameter: Type number YH10W-12Rated Voltage12KV(rms)Imax Continous operating voltage10.2KV(rms)1/10μs steep wave current impulse residual voltage42.2KV8/20μs Lightning impulse current residual voltage36KV30/60μs Operating impulse current residual voltage31.7KV2ms Rectangular current impulse withstand(A)Norminal discharge current250A(10KV)150A(5KV)4/10μs High current impulse withstand(KA)Norminal discharge current100A(10KV)65A(5KV)
