Line Surge Arrester Solutions

Enhance System Reliability

Every lightning strike, insulator flashover, or switching surge adds wear and tear to valuable equipment. Momentary interruptions caused by lightning can disrupt our day-to-day activities and pose a risk to large facilities, such as manufacturing plants and hospitals. Protecta*Lite® line surge arresters improve line reliability, reduce costs, and extend the life of transmission assets.

Protecta*Lite is designed and configured to prevent lightning from flashing over line insulation. The lightning surge is safely diverted to the ground in a controlled manner, and the resulting voltage is limited to a level below the insulation strength. Available for applications ranging from 2.4 kV to 765 kV, Protecta*Lite safeguards overhead lines with a product line that includes both non-gapped line arresters (NGLA) and externally gapped (EGLA) line arresters.

Externally Gapped Line Arresters

The EGLA, which consists of a series varistor unit (SVU) and a series gap, is the most recent addition to our line of surge arrester solutions. Its design can be especially advantageous for compact towers and EHV or UHV networks because it eliminates the need for a direct line-to-ground connection. Consider integrating an EGLA during the design stage of the transmission project to create an effective defense mechanism to protect your grid investment.

Hubbell designs, tests, and manufactures unique EGLA designs for your specific application. Hubbell can customize an EGLA design for your system voltage and preferred mounting style. Choose an EGLA solution for the benefits of added protection for your line and less hardware for your crews to assemble.
