Study on the Application of Pressure Grouting Composite Resistance Reduction Technology in the Transmission Line Grounding Engineering

Transmission line tower grounding is the most basic protection technology of current transmission line lightning protection.According to the current transmission line tower grounding resistance reduction technology requirements, this paper studies a new type of transmission line grounding resistance reduction technology, namely pressure grouting composite resistance reduction technology. Firstly, the structure of the device and the principle of resistance reduction technology are introduced. Secondly, based on the actual project, the advantages and effects of the grounding resistance reduction technology in the aspects of grounding resistance reduction, structure construction and economic cost are demonstrated. In order to provide reference for similar engineering applicatio.
