Catenary, SWA pole type

    I need to run some 6mm cable from my house up my garden. The only option (without digging up driveways and paths) is overground. I was thinking of placing a pole at one end and attaching some catenary cable back to the gable end of the house (at the other). I have two questions:

    Will this be acceptable for a 15-20 meter span, or is there a requirement for a pole inbetween?

    Is there a requirement for the type of pole I should use? I would like to get it up around 4-6 meters (it is over the back garden, no cars etc)


    thanks

    Unfortunately not. The house is out on it's own with no walls anywhere near it, the perimeter fence is miles away!

    It’ll look crap
    You’d be better off burying it.

    I agree with the others. It would look awful. I would far rather dig up the driveway and paths.

    Yeah, it might look awful but I really have no choice. The driveway and paths cost a lot and herself just wouldn't go for it.

    So, apart from it looking bad, is there anything technically unsafe? Is there any particular type of pole required or can use normal aerial type pole?

    Catenary wire and tie wrap the SWA to it

    Surface clipped or buried is the norm

    Use an impact mole to cross the driveway

    It’s a bad plan, end of.
    My advice: Talk to “herself”, save up the money, do it once and do it right.

    It can be done safety.

    Yes it’s called “an expensive pole” :D

    A pole for an arial is unlikely to be strong enough. I think that you will find that many electrical contractors will not be keen on putting their name to this.

    Yeah an impact mole is the best if you want to cross the driveway without cutting it.

    I'd advise against the overhead solution, it's going to look awful and it may sag over time.

    You still have to bust out the path at the house side to pick up the mole pipe.
    I've recently cut my path with a 4" diamond disc and burried 2 25mm pipes.

    Didn't take long to do and didn't take long to repair .

    Has anyone used that mole system?
    Expensive solution?
    Does the ground need to be pretty soft / no rock?
