Taking the project of 500 kV GIL pipeline in Nanqiao substation as an example,this paper compares the GIL expansion joint without and with vertical regulation in terms of technique,construction period and economy by analyzing and calculating.The results show that by setting vertical expansion joints,the foundation bearing capacity will be fully utilized,and the construction difficulty,construction period and cost will be reduced,thus achieve a high comprehensive economic benefit.
