Based on findings like these, a minimum safety distance of 1/4 mile (1320 feet) might be considered prudent. And again, individuals with EMF hypersensitivity or other serious health issues may want to consider a much greater safety distance, perhaps a half mile, or even more. . The NESC requires vertical clearance between line conductors carried on the same supporting structure. If an angle exists at the MAXIMUM LINE ANGLE FOR THIS CONSTRUCTION IS 15 DEGREES. INSTALL UPPER POLE. . PURPOSE: To provide general construction requirements for representative wood pole structures and assemblies for 34. 5 through 69 kV transmission lines. After a brief description of IBRs and distance protection, the reported problems are classified based on their causes and effects. This method has been incorporated into short-circuit. . This article focuses on the feasibility study report of 35kV and below transmission lines and the design ideas encountered in the preliminary design, Problems and their precautions for analysis.
