Mv Composite Metal Oxide Surge Arrester Without Gaps

mv composite metal oxide surge arrester without gapsMain features:1. The Core column applied winding structure, Polymer Housed core pillar molded on the core column, with almost no internal air gap, and outstanding sealing performance Simple in structure, small in size and light in weight. 2. Polymer Housed with silicone rubber, explosion-proof ZnO varistor as the core component is largein flow capacity.3. International standard IEC 60099-4 and ANSI 62.22, and with high reliability. With fully insulated tops, the product can be applied to the complete cabinet installation, which can reduce the designing size of cabinet. 4. Products with detachment device can provide signals for quitting operation when failure occurs,avoiding arrester explosion, and it is maintenance-free. 5. Polymer housed products with a six CTI level, creepage distance meets the requirements of IV level in heavy pollution areas.Technical Parameters:TypeYH10W5-18/49.54/10µS High current impulse kA100Rated voltage---------kV18Lightning impulse withstand kV150MCOV ----------------kV15.3Power frequency voltage withstand(dry/wet)kV38Nominal Current-------kA100.1S TOV--------------kV21.6Residual voltage of steep impulse----at 5kA(kV)53.31S TOV----------------kV20.78/20µS Residual voltage of lightning impulse current kV(Peak value)-----at 5kA(kV)49.410S TOV---------------kV19.8Residual voltage of switching impulse current kV (peak value)----at 1kA (kV)37.81200S TOV-------------kV181mA D.C reference voltage (kV)25.5Creepage distance ----mm596Line discharge level1Material employed in series non-linear resistorZinc Oxide2mS long duration impulse current A400Material of housingsilicon rubberSurge Arrester Drawing:Environment temperature: -40--+40 degreealtitude:
