早在1917年,宜兴已经开发和使用电力。在旧社会宜兴的电力事业发展和其它建设事业一样,经受了漫长和曲折的历史过程。解放后,特别是十一届三中全会后,在中国共产党的正确领导下,宜兴的电力事业由小火电、小规模,逐步发展到220千伏的大电网供电,供电网架由110千伏和35千伏混合网架逐步过渡到以110千伏为主的供电网络,再由一乡一线向一乡一变发展。1978年,我市仅拥有35千伏以上变电所7座,主变容量72350千伏安,其中:110千伏变电所2座,主变容量6300千伏安;35千伏安变电所5座,主变容量9350千伏安。110千伏线路2条/53.1公里,35千伏线路11条/120.351公里,10千伏线路23条/1025公里。配电变压器1193台/135845千伏安。
As early as 1917, Yixing has developed and used electricity. In the old society, the development of the power industry in Yixing, like other constructions, has undergone a long and tortuous historical process. After the liberation, especially after the Third Plenary Session of the 11th CPC Central Committee, under the correct leadership of the Communist Party of China, Yixing’s power business has gradually expanded from small thermal power to small-scale 220 kV power supply. The power supply grid consists of 110 kV And 35-kilovolt hybrid grid gradually transition to the 110-kilovolt-based power supply network, and then from a rural line to a rural change. In 1978, the city only has 7 substations above 35 kV, with a main transformer capacity of 72,350 KVA, of which 2 are 110 KV substations with 6300 KVA main transformer capacity and 35 KVA transformer substations The 5, the main transformer capacity of 9350 kVA. 110 kV lines 2 /53.1 km, 35 kV lines 11 / 120.351 km, 10 kV lines 23/1025 km. 1193 distribution transformers / 135,845 KVA.
