Medium Voltage 27kv 5ka 10ka Metal Oxide Silicone Surge Arrester

Medium Voltage 27kV 5kA 10kA Metal Oxide Silicone Surge Arrester0.28kV~500kV Surge Arresters' Characteristics: 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:TypTypeYH10W5-33/90Rated voltage---------kV33MCOV  ----------------kV27.5Nominal Current-------kA10Residual voltage of steep impulse----at 5kA(kV)97.58/20µS Residual voltage of lightning impulse current kV(Peak value)-----at 5kA(kV)90Residual voltage of switching impulse current kV (peak value)----at 1kA  (kV)68.71mA D.C reference voltage (kV)46.7Line discharge level12mS long duration impulse current A4004/10µS High current impulse kA 100Lightning impulse withstand kV200Power frequency voltage withstand(dry/wet)kV700.1S TOV--------------kV39.61S TOV----------------kV37.9510S TOV---------------kV36.31200S TOV-------------kV33Creepage distance ----mm1082Material employed in series non-linear resistorZinc OxideWorking condition:Environment temperature: -40--+40 degreealtitude:
