About the Project:

630KVA substation
Our client approached us with the requirement of improving their eletrical system , and Construction of 22KV 630KVA transformer substation and connection line in Binh Duong Province, Vietnam. These constructions were to bring the factory power system with higher capacity as factory expand production. What’s more is that these improvements must be made without interfering with current operations. Of course, we were happy to help!

We were engaged to tackle the detail design and make relevant documents with EVN. In addition we also managed the schedule and optimised the costs for the work, which is due to be completed at the end of 1/11/2021.

Why Quang Anh for construction of 22KV 630KVA transformer substation?

From our initial discussions with our client, we were keen to demonstrate our expertise and experience in this field, having worked on substation constructions projects previously.
We are also well-versed in working while plants remain operational, and have a great deal of experience when it comes to meeting international safety standards. We were delighted to be chosen for this project with our client citing their reasons as our specialist capability working in Electrical, as well as our capacity as a consultancy and construction firm to effectively take on the project with our in-house expertise.

630KVA substation

We are delighted that this project is well underway. And we can confirm that construction of 22KV 630KVA transformer substation and connection line to meet safety standards are taking place while the plant remains operational, exactly according to our client’s requirements. Projects like this are right up our street – we love them!
