The paper considers the possibility of using high-voltage power cable
channels for transmission of information in power engineering. It is s
hown that the analog information attenuation along the core-sheath pat
h for cables of 35 and 110 kV is 1-0.5 dB/km. Attenuation of the sheat
h-armour path is 1.5-2 dB/km. When using a binary code, the allowable
length of the channel core-sheath for 110 kV cables at an information
transmission speed of 100-250 kbaud is 30-5 km. Copyright (C) 1996 Els
