Cathodic protection station - SKZ

The station is designed for electrochemical (cathodic) protection of underground metal structures (gas pipelines, oil pipelines, public utilities, etc.) from electrochemical corrosion. The station provides reliable stable operation under the influence of climatic factors of external environment at relative air humidity not exceeding 98%. The operating mode of the station is prolonged, continuous. The station is designed for operation in electric networks of TN-S and TN-C-S systems according to GOST R 50571.1-2009, while combining the functions of zero protective and zero working conductors in one conductor is allowed when the station is supplied by a branch line from a high-voltage line of electric networks of TN-C-S system with voltage up to 1 kV, while TN-S must have a separate third conductor as a zero protective conductor. The station is designed according to the block principle. The units are placed in a metal case. The casing provides protection degree IP34 according to GOST 14254-96.
