like h3ll it will, ntl cabled through garden, not at 18" min but at 1.5 inch guess what im alway chopping through it when im gardenin.
ntl said well can you not dig so deep ..na cable should not be there so they sleeved it and put it back at 1 inch deep to top of sleeve.
......
like telephones the cable does have milivolts or rens as bt call them, these are so little danger thats its safe to cut through no problem etc.
use of such small non amped volts is to speed the rate of which signals pass through and thats about it.
wouldnt worry at all about cable tied to gas pipe unless its causing strain damage.
BT do not call them RENs, that it the ringing equivalence number.
NTL and most other Telcos will clip their cable to anything and everything. I suggest the OP either gets on with his life or considers himself thankful it has not been pushed inside the hedge or laid on the surface of his driveway.
In my day my BT colleagues considered a clip an unnecessary contrivance and a delay between the job and the caff.
I would suggest if it look reasonably neat leave well alone. If you call out NTL they will propably make it look 10 times worse.
is that not influenced by voltage within the line itself, ie most domestic properties have a ren of at least 3 in which after that is exceeded the telephones may not ring at all !!! been there and done it exceeded ren long time ago.
as i say eitherway voltage so so small that it posses no risk, im sure cable works the same way where milivolts are used to speed teh signal transfer to customers homes/property. again i have hacked through cable a couple of times without any problems and the repairers just joint the cable as it is(one one repair joint allowed on cable)
