Transmission Lines

This feature class/shapefile represents electric power transmission lines. 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. The following updates have been made since the previous release: 1,166 features added.

本数据集的要素类/形状文件代表电力输电线路。输电线路由一系列结构、导线、绝缘体及其相关硬件组成，用于将电能从一个点传输至另一个点，构成电力系统。线路运行在相对较高的电压下，电压范围从69千伏至765千伏不等，能够在大范围内长距离传输大量电能。当有资源可用时，还包括地下输电线路。自上次发布以来，已进行了以下更新：新增1166个要素。
