Electrical inspectors involved with aerial high voltage facilities frequently have to determine whether electrical conductors are in compliance with the National Electrical Safety Code (NESC).
The National Electrical Safety Code® (NESC®) occasionally references other standards. For example, ANSI Z535.1-1991 through ANSI Z535.5-1991 inclusive are referenced many times within the NESC.
In Part 3 (July/August issue) we determined the height of our structures and the strength of our structures and foundations to comply with the National Electrical Safety Code® (NESC®). The last step in the design of a high-voltage overhead line up to 50 kV to comply with the NESC is to design the guying.
