Desain Pemodelan Andongan Dan Ketegangan Untuk Saluran Transmisi 275 Kv Menggunakan Metode Catenary
This research develops a method for determaining catenary sag and tension analysis on 275 kV transmission line conductors. Catenary method is a function of the weight equation conductor, wires maximum tensile stress, long-span, and the maximum sag of the conductor. Processing methods was is used to determaine the value of the sag and tension with the design of the model using statistical software Autocad, as well as determining the value of sag and tension of the influence of temperature conductor due to the current flow and ambient temperature using data conductor types A1/SA1A (ACSR/AS), the results of this research for the same tower height is obtained sag of 6.86 m, with a value of 4610.83 kg tension and conductor length of 401.06 m, for the not same tower height is obtained sag of 8.14, with a value of 4612.84 kg tension and conductor length of 401.06. Any increase in the current then sag value will increase, when the minimum current generated sag value of 6.9828 m, when the maximum current the resulting sag value increases to 8.44 m. While the value of tension obtained will be reduced, when the minimum current value of the tension is 4531.57 kg, when the maximum current value of tension is 3749.728 kg, Any increase in ambient temperature sag value will increase, when the minimum temperature is 20 the resulting sag value of 6.8621 m then when the maximum temperature is 40 the resulting sag value increased to 7.793492 m, While the value of the tension will decrease, when the minimum temperature value amounted tension 20 4610.538 kg, when the maximum temperature is 40 tension value of 4062.345 kg. The combination of temperature due to current flow and ambient temperature of the sag value obtained is greater, it can be seen that the temperature difference of 50 sag value is 9.43 m, while the tension value is 3362.057 kg.
