The Importance Of Metal Oxide Surge Arresters


SMC metal oxide surge arrest provides a level of surge protection from a DC distribution system in mining and industrial applications. These are designed to be mounted along a metal and pointed up on substations, DC feeders, centenary poles, power rail and substations. A complete ground is able to establish a connection of less than 5 ohms. 

The arrester’s utilize metal oxide technology that’s been proven in the transportation industry. They’re designed to operate at temperatures not exceeding ± 2°C in the housing is manufactured out of an extremely strong impact resistant and UV stabilized polyester glass compound. Full elements can be encapsulated within the device and the unit is fully sealed with a stainless steel cap. Connecting studs and mounting hardware are also built with a corrosion resistant stainless steel. Any energy discharge capacity of the device offers support for less than 500 apps or 2.6 KJ. 

The devices are extremely important to maintaining power in a rail system and for protecting a wide range of equipment. The arrester can be installed to deliver a maximum continuous operating voltage and a level ground for a wide range of electronic components. Though the stabilized components are the highly resistant compounds in construction, we can establish a greater quality for the arrester and a more sustained level of protection for electronics in the future. Operating any type of sensitive electrical equipment or required rail equipment at high voltages will ensure that you will also need to be running using proper grounds and surge arresters for protection.

These are devices that can prevent downtime, save lives, prevent accidents and save equipment. If you are interested in getting the best in surge arresters for your business, contact us today to learn more.
