The author introuduce the application on engineering surveying for overhead transmission line with RTGPS in Fujian mountainous area.

This paper introduced the replacement of surveying technique of overhead transmission line with the comparison between traditional surveying method and RTK surveying.

This paper introduces the method adopted to organize the database by using many kinds of data and the software adopted to manage these data in geographic information system for overhead transmission line.

To solve the faults caused by lightning stroke in 35kV overhead transmission lines, it is proposed to use shunt gap as the lightning protection.

Engineering Surveying Method of GPS in Aerial Power Transmission Line;

ArcGIS-based Value-added application development for 500 kV transmission line information management systems;

In the light of the difficulties in the replacement of tension-resistant insulator string of 500 kV transmission line,such as the difficult fix of working tool,the complicate procedure,the limited operation space and the difficulties in the dismantle of bowel plate,etc,a new idea of shifting the tension of transmission line by using of double interconnection plate was put forward.

In recent years, windage yaw flashover frequently occurs in 500kV transmission lines, and the frequency of such accident exceeds the receivable limit of power system secure operation.
