We manufactures a wide range of line surge arresters to meet each application’s unique requirements. All  surge arresters are qualified to the latest version of IEEE C62.11 or IEC 60099-4. The EGLA product line is qualified to the latest version of IEC 60099-8. Lightweight, easy to handle polymer arresters are exclusively used for all Hubbell line arrester applications. Several design types are available to meet varying isokeraunic levels and mechanical requirements for each client’s specific needs. Hubbell line surge arresters are installed in various environments across the world and continue to improve system reliability.

This web listing represents a sampling of typical configurations. ProtectaLite Arrester assemblies can be customized for all distribution and transmission lines.Selection of arrester MCOV size is based upon the maximum continuous voltage that is applied across the arrester in service (line-to-ground). For arresters on effectively grounded neutral systems, this is normally the maximum line-to-ground voltageExample: 84 kV on a 138 kV system. For ungrounded or impedance-grounded systems, the MCOV should be at least 90 percent of maximum phase-to-phase voltage.For more information about arrester selection, please contact your Hubbell Power Systems representative.
