Kita-Iwaki powerline

The three-phase line Kita- Iwaki is a double-circuit power line for three-phase alternating current in Japan. It was built in 1999 and runs from the rear derailleur South Iwaki (南 いわき 開閉 所, Minami- Iwaki kaiheisho, 37 ° 22 ' 53 "N, 140 ° 48' 16" O37.381388888889140.80444444444 ) at Tamura for substation East Yamanashi (东山 梨 変 电 所, Higashi - Yamanashi handensho, 35 ° 35 ' 26 " N, 138 ° 47' 59" O35.590555555556138.79972222222 ) in Otsuki. The high-voltage line is currently operated with an electrical voltage of 500 kV, but can be changed in the future without major modifications to 1.1 MV.

As head of bundle conductors come with eight strands and 31.5 millimeters in diameter are used. The line is designed for a maximum current of 4 kA. She's moved to 108 meters high on average masts with three crossbars; the spans of trusses be 33, 32 and 31 meters (lower, middle and upper ).

There are two such paths: the first 190 km long route starts at the nuclear power plant, Kashiwazaki - Kariwa and runs the main line west Gunma (西 群 马 干线, Nishi- Gunma Opportunities and Combating ) from the rear derailleur West Gunma (西 群 马 开 闭 所, Nishi- Gunma kaiheisho, 36 ° 37 ' 22 " N, 138 ° 48 ' 6" O36.622777777778138.80166666667 ) at Nakanojō for substation East Yamanashi. It was built in 1993. The second, built in 1999 line with a length of 240 kilometers, consists of the main line east Gunma (东 群 马 干线, Higashi - Gunma Opportunities and Combating ) from the substation West Gunma for substation East Gunma (东 群 马 変 电 所, Higashi - Gunma hendensho; 36 ° 34 '46 "N, 139 ° 13' 26" O36.579444444444139.22388888889 ) with Kiryu and the main line south Iwaki (南 いわき 幹線, Minami- Iwaki Opportunities and Combating ) of West Gunma for derailleur South Iwaki. They also passed the derailleur Shin- Imaichi (新 今 市 开 闭 所, Shin- Imaichi kaiheisho, 36 ° 42 '46 "N, 139 ° 49' 57 " O36.712777777778139.8325 ) in Nikko, but which has no connection to this line features.
