METAL OXIDE DC SURGE ARRESTOR
METAL OXIDE DC SURGE ARRESTOR
GENERAL SMC Metal Oxide DC Surge Arrestors provide surge protection for DC distribution systems in transit, industrial and mining applications. The arrestors can be mounted in rectifier substations at the DC feeder, on catenary poles, at the power rail or on a vehicle. The unit should be mounted as close as possible to the devise it is protecting. The arrestor and device should be connected to an appropriate sized ground for anticipated surge leads. Arrestor selection is based on line to the ground maximum continuous operation voltage (MCOV)
DESCRIPTION The DC Surge Arrestors utilize metal oxide technology, that has been proven in station and intermediate class arrestors. They are designed to operate in temperatures not exceeding 60°C. The arrestor housing is manufactured of impact resistance UV stabilized polyester glass compounds with the element encapsulated. The element’s encapsulated area also has a high dielectric sleeve for added protection. The unit is sealed with a stainless steel. cap. The conniption studs and mounting hardware are manufactured from corrosion resistance stainless steel. Energy discharge is 2.6kj/kV for current < 500 A.
