Detailed Description

15KV Polymer Metal Oxide Gapless Surge Arrester with KEMA Specifications: 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. Product characteristic: 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 Applications: The zinc oxide arrester is mainly used to protect distribution transformer,cable connector and electrical equipment from being damaged by lightning impulse voltage and operating over-voltage. YongDe metal surge arrester since 1993 years. - - - - Type | YH10W5-15/41.2 | | | Rated voltage---------kV | 15 | 4/10S High current impulse kA | 100 | MOCV ----------------kV | 12.7 | Lightning impulse withstand kV | 110 | Nominal Current-------kA | 10 | Power frequency voltage withstand(dry/wet)kV | 28 | Residual voltage of steep impulse----at 5kA(kV) | 44.5 | 0.1S TOV--------------kV | 18 | 8/20S Residual voltage of lightning impulse current kV(Peak value)-----at 5kA(kV) | 41.2 | 1S TOV----------------kV | 17.25 | Residual voltage of switching impulse current kV (peak value)----at 1kA (kV) | 31.5 | 10S TOV---------------kV | 16.5 | 1mA D.C reference voltage (kV) | 21.2 | 1200S TOV-------------kV | 15 | Line discharge level | 1 | Creepage distance ----mm | 500 | 2mS long duration impulse current A | 400 | Material employed in series non-linear resistor | Zinc Oxide | - - - -
