Long DC runs or long AC runs on ground mounted systems

… do you know any good suppliers of large SWA like this. can't see CEF doing it too cheaply!!

Have a look at:

Industrial SWA Cables

I bought some 10mm 4-core recently and they were a pound a meter less than anyone else. (And it didn't have mud all over it and the end hacksawed off )

16mm 2-core £3.40/m Not sure how it compares. TLC is £4.05.

Evel cables also used to be good, but their web site has been ‘closed’ for ages.

CSE, last time I got a quote for SWA, was expensive.

My wind turbine is connected with 450m of 3 core 16mm SWA (the turbine output is 3-phase wild AC). Putting it in was pretty easy even from a 500kg drum held just off the ground on a scaffold frame. I'd also suggest avoiding joints.

Get U MY WIND TURBINE !!! lol 450mtrs wots volt drop on that?? oh yeh is it that far cause u have a big garden or u nicked a supply from the local wind farm ps NO JOINTS always trouble (in the end)

Oh don't apologise It's not ME who's flogging cable - that was a link to an internet reseller I use. I don't know if I misinterpret it, but they do appear very cheap.

Just got a price out of interest from our rep at CEF and we get it at £3.18/m , with our early settlement discount it would be £3.10/m .
Reckon you could batter your suppliers down even more !:6:

I'm looking at 4 core, cos I'm running two strings. (the run is for the DC)
the internet guys above came out at about £2700 for 400m

What's your dc voltage? Have you considered redesigning the strings to increase the voltage so you can drop a cable size? Could save a thousand quid.

Maybe even one string on two core? Or are you already maxed out on Vdc?

 

[moggy1968]

The problem is the differing orientations of the panels so I need to run it on 2 trackers, so the strings have to go back to the inverter.

 

[beefheart]

just been quoted £3.04 /m for 16mm 2 core local wholesaler is cable getting cheaper by the day?

 

[SolarCity]

Maybe the Chinese have stopped buying it all

My local supplier told me cable prices went up 6% last week!
