Abstrak: Saluran transmisi udara umumnya menggunakan konduktor jenis ACSR (Aluminium Conductor Steel Reinforced) yang memiliki batas temperatur kerja yang diizinkan sebesar 90 o C. Permasalahan utama dari penggunaan konduktor ACSR adalah timbulnya andongan dan tegangan tarik. Andongan dan tegangan tarik dapat meningkat akibat arus saluran, tekanan angin dan temperatur lingkungan. Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh arus saluran, temperatur lingkungan, dan tekanan

Hasil penelitian ini menunjukkan bahwa andongan dapat meningkat sebesar 0,00012% akibat pengaruh 1 Ampere arus saluran, 0,415% akibat pengaruh 1 o C temperatur lingkungan, dan 0,0002% akibat pengaruh 1 m/s kecepatan angin. Tegangan tarik tidak berubah apabila dipengaruhi kenaikan 1 ampere arus saluran, tetapi dapat meningkat 0,000001% apabila dipengaruhi1 m/s kecepatan angin. Sebaliknya, setiap kenaikan temperatur 1 o C, tegangan tarik berkurang 0,0407%. Abstract: Most overhead transmission lines use with a type of ACSR (Aluminum Conductor Steel Reinforced). This conductor has a limited temperature up to 90 o C. At present, the need for electricity is increasing rapidly. The need for reliable electricity transmission is demanding. Problems associated with the transmission lines are sagging and tension of conductors. The sagging and tension can be increased as a result of current flowing transmission line, wind pressure, and temperature. The effect of internal and external factors are investigated by using caternary method. Therefore, in this research results show that an increase in 1 ampere of current this conductor can increase sagging as much as 0,00012%, and an increase in 1 o C of temperature can produce sagging as much as 0.415%, while an increase in 1 m/s of wind speed can yield a sagging of 0.0002% .Meanwhile, there is no effect of the amount current flowing in transmission line to the increase of tension, but the increase of tension mainly effect by the increase 0.000001% because 1 m/s of wind speed, in temperature an increase 1 o C of temperature in decrease tension 0.0407%.
