变压器把电压转化为220千伏，然后从110千伏转化为10千伏。只有以这种方式，电力才能被配送到城市电力网。
Transformers convert voltage to 220, then from 110 to 10 kV and only in such form electricity is fed into the town network.
港灯的输电系统分别以275千伏特、132千伏特和66千伏特功率输电，配电则主要采用11千伏特和380伏特功率。
HEC's transmission system operates at 275 kV, 132 kV and 66 kV and distribution is effected mainly at 11 kV and 380 volts.
