First, the use of lightning arresters electrical one, is one of the widely used electrical. For arresters we all know some, this is not the lack of high-rise buildings. Arrester similar harmonic elimination, divided into many. CHINA Electrical boutiques to introduce you to several of the arrester model. Distribution arresters: used to protect distribution transformers, switchgear, box-type variable, cable head column switches and other small oil distribution equipment from atmospheric over-voltage and over-voltage damage. Plant arresters: used to protect power plants, substations equipment from atmospheric over-voltage and over-voltage damage. Parallel compensation capacitor arresters: vacuum switch for suppressing or less oil switch capacitor switching overvoltage generated renewed protect the capacitor bank from operating over-voltage damage. Its use: Ambient temperature -40 ℃ - + 40 ℃; altitude less than 2000m; power frequency 48Hz- 62Hz; seismic intensity of 7 degrees and the following areas; maximum wind speed does not exceed 35m / s; long applied to the arrester work frequency voltage should not exceed its continuous operating voltage.
