Technical Code of Exploration and Surveying for 220kV and Lower Level Overhead Transmission Line

Issue Date: June 04, 2008 Implementation Date: November 01, 2008
Issued by the National Development and Reform Commission of the People's Republic of China

1 Scope
This code specifies the basic technical requirements for exploration 220 kV and 110kV overhead transmission lines engineering.This code is applicable to the geotechnical engineering, survey and engineering hydrological exploration of 220 kV and 110 kV overhead transmission lines that are newly built and modified. The exploration of overhead transmission lines engineering at a voltage level below 110 kV may refer to the relevant requirements of this code according to the actual conditions.
