METAL OXIDE SURGE ARRESTERPolymer housed for outdoor applicationFeatures Better Electrical performance & reliability Ease of Installation-Light weight & smaller size Better Operating conditions Explosion & shatter proof & less mechanical damage to nearby equipments Better performance in polluted environment Vandalism resistant Free from Moisture ingress Higher safety Higher mechanical strength Insensitive to UV radiation High resistance to Ozone & Corona Excellent Tracking resistance Performance Data System Voltage Rated Voltage (kV):0.1-275 Nominal discharge current (kA) High current capability (4/10us) kA Energy Class : Energy absorption Capability kJ/kV Short Circuit (Pressure relief) kA:40 Standard in accordance with:IEC60099-4 Porcelain housed for outdoor application  For protection of transformer & switchgear. Highly non-linear MOV. Explosion Proof - Pressure Relief Design. High energy handling capacity. Glazed brown Porcelain Housing. Corrosion proof Aluminum alloy metal flange. Suitable for Ambient -400C to +550C. manufactures effective surge protection device with the modern technology of highly non-linear Zinc Oxide Varistor blocks and thus diverts natural lightning surge and switching surge to earth and simultaneously clip off any follow on current. Our station class arresters are designed to provide maximum safety to personnel and sub-station equipment even at the enormous short circuit duty. Research and Development is an ongoing process at Elektrolites with the active collaboration of experts in the industry.
