“Ekibastuz SDPP-1" named after B.Nurzhanov” LLP completed the investment project for modernization and expansion of open switchgear (OS-500 kW) worth 18 billion tenge (with VAT).
Modernization of 500 kV - outdoor switchgear will increase the reliability of power generation by power units of Ekibastuz SDPP-1.
In addition, 500 kV outdoor switchgear of ESDPP-1 is essential for the operation of National Power Grid (NPG) of Kazakhstan. Six major 500 kV overhead power lines which belong to “KEGOC” JSC and that ensure flows of electricity and capacity in the region including flows through interstate transmission lines connecting Kazakhstan and Russia move off from 500 kV OS.
The works on replacement of obsolete air-insulated switchgear to gas-insulated, measuring current and voltage transformers, disconnectors were carried out during the performance of construction and installation works in November 2012. Also works on expansion of 500 kV- OS for a separate connection of power unit No.8 were conducted. In order to avoid severe accidents including simultaneous disconnection of two power units, power units No. 5, 6, 7, 8 were divided by laying 500 kV cable lines for units No.5 and 7.
Up-to-date equipment such as gas- insulated switchgears, shunt reactors, microprocessor-based protective relay devices and automation, systems of monitoring and control over operation of electrical equipment and others were applied within the project.
Implementation of the project will increase the service life of electrical equipment, increase the reliability of power supply to consumers, as well as reduce operating costs.
