One of the successfully implemented investment projects of AEDC JSC in 2017 is the modernization of the “Zholymbet” Substation with a capacity of 220/110/35/6 kV in the Shortandy District. The Substation was built in 1964 for the needs of the mining industry. At present, the Substation provides electric power supply to the village of the same name, two mines and the ore mining and processing mill of Kazakhaltyn JSC, and the most of the neighboring Ereimentau District as well.

Annually, the substation carries out modernization and reconstruction works replacing equipment. Last year, four oil breakers of MKP-110 kV were replaced with gas-insulated ones of VB-110 kV and a new telematics equipment was installed there: “Iset” Remote Station of the ARISSSCADA Software System. It is designed to collect, process and transmit remote signals and remote measurements to the dispatcher panel of the Central Dispatching Service of AEDC JSC and the Operative Dispatching Service of StepnogorskInterdistrict Electric Power Networks. Prior to the replacement, the “Compass” Remote Station was used, whichoutlived its usefulness over the years of operation.

The introduction of the modern equipment at the “Zholymbet” Substation is aimed at ensuring the reliability of electric power supply to consumers.
