MES of Western Siberia set on a perimeter substations 500 kv Pyt’-yakh (Khanty-mansiyskiy autonomous district – Yugra) metallic protection a height a 2,5 m with an additional overhead protection «Egoza» and nizhnim – for protecting from undermining, – executed from an armature
became. On all perimeter of substation on the special bars sensors are set with radial access control. At crossing of ray on the clock-house of substation a signal acts about unauthorized penetration on territory of energoob’ekta. For the operative informing

result of the executed works reliability of guard of energoob’ekta, providing the power supply of users of the Nefteyuganskogo district of Yugry is enhanceable. The cost of works exceeded 12 million roubles.Substation 500 kv Pyt’-yakh by power 1 252 MVA put into an operation in 1976
