Insulation & Its Role in Line Optimization Studies

Transmission line projects face different challenges than in the past. Greater emphasis on environmental impact, aesthetically pleasing designs, public acceptance, lowering costs and minimizing right-of-way widths all must be considered while still maintaining a safe, robust, and reliable system. Porcelain, glass and composite insulator strings have stood the test of time but the advent of alternatives such as line posts, braced posts and composite insulated cross-arms allow for different head designs to better manage these challenges. This presentation reviews the optimization study process and discusses the considerations that must occur to lead to an optimal design for 138 kV & 240 kV lines.
