1. What qualifications are required for the installation of fire protection systems in Class A explosion-proof areas? 2. What qualifications are required for a 10KV substation? It would be great if you could provide the document evidence; thank you very much!

For Class A explosion-proof areas and 10KV power distribution, **Grade I construction enterprise qualifications** are required；
