Detailed Description

24 KV Gray MOA Electronic Polymeric Polymer Lightning Arrester Used in Substation Introduction: YongDe Surge Arresters can be applied to a variety of systems including substation equipment, AC-DC converters, railway power system and power distribution units ranging from 0.25kV to 765kV systems. These surge arresters demonstrate excellent protection properties. YongDe surge arresters incorporate YNR elements (YongDe Non-linear Resistor ZnO Elements) with superior non-linear voltage-current characteristics, high quality and reliability. Metal oxide type surge arresters offer such special features inherent in the gap-less structure, such as a quick response to surge voltage, high energy dissipation capability, safe operation, compactness / lightweight and freedom from pollution. Features: 1. Compact and Lightweight 2. Extremely Safe Pressure Relief Performance 3. Superior Performance against Environmental Contamination 4. Directly Molded Structure 5. Compliance with International Standards(IEC60099-4) 6. Simple Support Structure 7. Manufactured at Advanced ISO-9001 certified facilities Specifications: Model:YH10W-24 Specifications 1.ISO9001 quality management system 2.Own test laboratory 3.To provide the corresponding product components 4.The technical performance is accordding to IEC60099-4 and IEEE(ANSI)C62.11 Main Technical Parameter Rated voltage r.m.s: 24kV Nominal discharge current:10kA Maximun continous operating voltage(Uc)(kV):20.4kV Residual voltage at: 1/4 s lightning current impulse residual voltage(kV):78.1 8/20 s lighting current impulse residual voltage(kV):71.0 30/60 s switching current impulse residual voltage(kV): 59.6 Long duration current impulse withstand: 2ms rectangular current(A):250 Operating duty: 4/10u s high current impulse(kA):100 Creepage distance(mm):800mm Dimension:405*211mm - - - - Type | YH10W5-24/66 | | | Rated voltage---------kV | 24 | 4/10S High current impulse kA | 100 | MOCV ----------------kV | 19.5 | Lightning impulse withstand kV | 150 | Nominal Current-------kA | 10 | Power frequency voltage withstand(dry/wet)kV | 50 | Residual voltage of steep impulse----at 5kA(kV) | 71.5 | 0.1S TOV--------------kV | 28.8 | 8/20S Residual voltage of lightning impulse current kV(Peak value)-----at 5kA(kV) | 66 | 1S TOV----------------kV | 27.6 | Residual voltage of switching impulse current kV (peak value)----at 1kA (kV) | 50 | 10S TOV---------------kV | 26.4 | 1mA D.C reference voltage (kV) | 34 | 1200S TOV-------------kV | 24 | Line discharge level | 1 | Creepage distance ----mm | 824 | 2mS long duration impulse current A | 400 | Material employed in series non-linear resistor | Zinc Oxide | - - - -
