10kV vs 20kV
10kV and 20kV transformers are suitable for different power grids. If your power grid is 10kV, you should choose a 10kV transformer; if it is 20kV, you must choose a 20kV transformer.
In some areas with heavy power loads, using a 10kV transformer may lead to insufficient power supply capacity, low power quality, increased number of lines, and large occupation of space. In such cases, a 20kV transformer is an ideal choice.
20kV transformer is very ideal for new construction or upgrading of power distribution systems!
20kV Transformer Power Distribution Solution
One of the main applications of 20kV transformers is in data centers. Due to the significant growth in AI computing power requirements, the load density of data centers is increasing. To satisfy this necessitating expansion, the 20kV power distribution solution is an ideal choice to address this challenge.
Here is the 20kV transformer power distribution solution provided by OMEK Power for a 6-story data center with a total electricity load of approximately 18,000kW.
