Exclusive Features of Overvoltage Protection Device
2.1 This device is applicable to AC power system ranging from 3KV to 6KV. Equiped inside of cabinet with vaccum switch, it is to absorb overvoltage during operation. Meanwhile, it has complete function of lightning protection.
2.2 This is a device of combining vibrating-absorption of high frequency and voltage limitation of high amplitude valved type, which could limit overvoltage most effectively during operation as well as great function of lightning protection.
2.3 Based on compound module design, users do not need to design individually with complicated calculations and select model. And the error probability of insulation co-ordination of electrical design is reduced a lot.
2.4 Adopted four-star & three-phascombined connection, the device meets actual needs of most power grids and the protective ability between phases is very strong.
2.5 The device is of dry design, completely sealed structure, safety and durability and tight beauty.
