As time passes, the company keeps making improvement in each project and set up new and higher standards. Insisting on combining practicability and aesthetics, the company accentuates maintainability and aesthetics. All of its projects are promoted by local headquarters as models, whether they are super-large lighting substation projects in Pudong International Airport or light substation reconstruction engineering of small and medium-sized airports in East China, North China, Xinjiang and Central South China.
