High Voltage Substation Lightning Arresters Manufacturers of 66kv Surge Arrester

High Voltage Substation Lightning Arresters Manufacturers of 66kV Surge Arrester 0.25kV~750kV 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. Surge Arresters' Technical Parameters:TypeY10W5-66/176Rated voltage---------kV66MCOV  ----------------kV52.8Nominal Current-------kA10Residual voltage of steep impulse----at 5kA(kV)2218/20μS Residual voltage of lightning impulse current kV(Peak value)-----at 5kA(kV)178Residual voltage of switching impulse current kV (peak value)----at 1kA  (kV)1371mA D.C reference voltage (kV)96Line discharge level12mS long duration impulse current A4004/10μS High current impulse kA 100Lightning impulse withstand kV325Power frequency voltage withstand(dry/wet)kV1400.1S TOV--------------kV79.21S TOV----------------kV75.910S TOV---------------kV72.61200S TOV-------------kV66Creepage distance ----mm2500Material employed in series non-linear resistorZinc Oxide Working condition:Environment temperature: -40--+40 degreealtitude:
