This study aimed to evaluate the ampacity and costs of different high voltage underground cable methods (cylindrical duct bank vs. square tunnel). The standards of Metropolitan Electricity Authority (MEA) of Thailand innovative approach to reduce road impact were used. Simulations for 115 kV cables showed that the maximum ampacity for cylindrical duct bank method was 523 A (flooding), and 509 A (non-flooding) while that of the square tunnel method was 445 A (flooding), and 405 A (non-flooding). Costs analysis were $573,446 per circuit for the cylindrical duct bank method and $404,363 per circuit for the square tunnel method.

Celem tego badania była ocena obciążalności prądowej i kosztów różnych metod podziemnych kabli wysokiego napięcia (cylindryczny zespół kanałów vs. tunel kwadratowy). Wykorzystano standardy Metropolitan Electricity Authority (MEA) Tajlandii, innowacyjne podejście do zmniejszania wpływu na drogę. Symulacje dla kabli 115 kV wykazały, że maksymalna obciążalność prądowa dla metody cylindrycznej wiązki przewodów wynosiła 523 A (zalanie) i 509 A (bez zalania), natomiast dla metody tunelu kwadratowego wyniosła 445 A (zalanie) i 405 A (niezalanie). powódź). Analiza kosztów wyniosła 573 446 USD na obwód w przypadku metody z kanałem cylindrycznym i 404 363 USD na obwód w przypadku metody z tunelem kwadratowym.
