Last Data Update: 09/30/2024 U.S. Electric Power Transmission Lines This feature layer depicts electric power transmission lines in the United States. Transmission Lines are the system of structures, wires, insulators and associated hardware that carry electric energy from one point to another in an electric power system. Lines are operated at relatively high voltages varying from 69 kV up to 765 kV, and are capable of transmitting large quantities of electricity over long distances. Underground transmission lines are included where sources were available. 138 Kilovolt Transmission Line Data currency: 09/30/2024 Data modification: none For more information: Electricity Explained For feedback, please contact: [e-mail]本要素图层（feature layer）已归档，将不再进行更新与维护。最后数据更新日期：2024年9月30日。 美国电力输电线路（U.S. Electric Power Transmission Lines） 本要素图层用于呈现美国境内的电力输电线路。输电线路是指在电力系统中用于将电能从一处输送至另一处的杆塔、导线、绝缘子及相关配套金具组成的系统。此类线路运行电压相对较高，范围为69千伏至765千伏，可实现长距离大容量电力输送。若有可用数据源，则包含地下输电线路内容。 138千伏输电线路（138 Kilovolt Transmission Line） 数据现势性：2024年9月30日 无数据修改记录 更多信息请参阅：《电力详解》（Electricity Explained） 如有反馈，请联系：[e-mail]
