Energy workers will update the equipment of the largest energy hub in the Nizhny Novgorod region Posting in CHAT: Russia The branch of PJSC "Rosseti" - Volzhsky MES has begun replacing the support rod insulators (OPI) of disconnectors and busbar supports at the 500 kV Nizhegorodskaya substation. The purpose of the work is to prepare the electrical installation for the upcoming autumn-winter period. As a result, the reliability of power supply to consumers in the mountainous part of Nizhny Novgorod and the central regions of the region will increase. Energy workers will replace 28 OSI units with modern Russian-made analogues. This equipment is intended for insulating and fixing busbars or live parts of devices on grounded metal or concrete structures. Climatic and weather factors have a negative impact on the state of the ASI. Timely replacement of faulty and expired insulation helps prevent technological breakdowns. The capacity of the 500 kV Nizhegorodskaya substation is 1,004 MVA. Eight power transmission lines with voltages of 220 and 500 kV connect the power facility with the Cheboksary hydroelectric power station, 500 kV Luch, 220 kV Nagornaya and Zarechnaya substations. In total, it is planned to replace 807 OSI units at the Volga MES facilities as part of the 2024 repair campaign. Source link Source link
