Lightning Arresters

Lightning arresters are designed to prevent lightning surges (entering through the wiring) from damaging electrical wiring and appliances. Lightning arresters are sturdy. weatherproof, service-proven devices that immediately drain lightning surges harmlessly to ground. Installed at either the weatherhead or service-entrance box, lightning arresters discharge a surge in a fraction of a second. They will perform this protective function ova and over again, without any maintenance required, possessing the same long-life valve-type characteristics obtainable in higher-voltage distribution lightning arresters.

Proper selection and placement of lightning arresters permits the reduction in the insulation withstand strength of the major equipment in a station. This can have a significant impact on reducing the overall cost of the station. With their exceptional protection performance, lightning arresters are therefore the logical choice to protect the heavy investment in other capital equipment. They make a very attractive investment that improves both short-term and long-term profitability.
