Exterior armoured cable
Former Community Member
I need to run an outside armoured cable to a pond pump. I will install all the necessary protection devices. My question is can the cable be laid loose on the ground between trees or attached to the trees. I dont really want to dig a trench all the way over a 40metre run. Thanks
Hmm. SWA can be laid surface, indeed it may be safer than shallow burial in a flower bed for example.
It does not mean it is always a good idea - rather depends on chance of rodent damage or gardeners strimmers.
If it is not permanent, note that pop festivals and film sets leave miles of soft skinned cable (usually rubber) around the place and apart from the odd RCD trip, it is surprisingly safe.
You can go overhead, either in SWA or in something lighter, note that long spans (more than ~ 10m for 2.5mm 3 core )need a support wire, and anything in trees needs allowance for the tree to both move and to grow, so more 'droop' than you may imagine.
It is also possible to plant vertical scaff poles between trees and catenary between them.
Probably a bit more info about the situation will help the decision process.
