Control system, protection up to 500kV
The main equipment such as protective devices, control devices (BCU) in protection - control panels used equipment from the leading manufacturers in the world such as Siemens/Germany, GE/USA, etc.,
Other accessories such as test blocks, clamps, intermediate relays, etc., are all used from reputable and qualified manufacturers and in accordance with the regulations of the Ministry of Industry and Trade, EVN, etc.,
Substation is used to convert voltage from one voltage level to another voltage level. It plays a very important role in the power supply system.
▪ According to the task, people are divided into two types of substations:
▪ Intermediate substation, also known as main substation: This station receives power from the 35-220kV system, turns it into a voltage of 22kV, 15kV, 10kV, or 6kV, sometimes down to 0.4kV.
▪ Distribution substation: This station receives electricity from the intermediate substation and converts it into appropriate voltage levels to serve the loads of factories, buildings, urban areas, workshops...
