Wiring conveyors belt

[anydream]

Hi all,
first of all I'm sorry for my english because I'm italian and English is not my mother language.
I have to define the wiring system for several belt conveyors (indoor) and motor fans (outdoor) for an industrial plant. I have already done this work in Italy but not in UK, so I'd like to share your opinion in regard of the types of cable to use.
Cables involved:
1) power cables (sectional area from 2,5mm2 to 6mm2 ) for DOL motors
2) power cables (sectional area from 2,5mm2 to 6mm2 ) for Frequency Controlled motors
3) Instrumentation analog signals 4..20 mA
4) limit switch signals (24Vdc)
5) Electrovalve (24Vdc)
Cables lenght will be up to 70m and mechanical impact could be classified "medium severity".
For point 1) the choice is between SWA cables and non armoured cables (more flexibles) in cable tray and tube (like H07RN-F).
For point 2) i think H07 is not suitable because I need shielded cables so SWA seems the best solution. Any alternatives? Are the SY cables suitable for power motors?
For point 3) SY Cables seem the best solution
For point 4 and 5) SY or CY or H07
I read (part of) the BS7671, but for now I miss experience in using BS cables.
Any suggestions will be appreciated.
Thanks, Andrea.

Don't use SWA for any vibrating, moving or rotating equipment of any sort, use SY instead.
Correctly terminated.
However, much of this kit may well be outside the scope of BS7671.
For the motors on inverters, check manufacturers data.

check he's location 7671 is out the window

So why is he asking about installing to 7671 & using cables to meet 7671?
The out of scope bit will actually apply in Italy anyway as it is an EN Std.

I thought he was asking about wiring in the UK :thinking:

My doubt about "SY cables" is that they have a 300/500 voltage rating and usually for 400V motors I used 600/1000V
I thought that all electrical installations in the UK were under the BS7671, why this wiring could be out of scope of BS7671?
P.S. I'm asking about wiring in the UK.

Exactly, you are right

 

[benji]

do you have a electrical installation to do in the UK or are just trying to gain information about UK electrics

I have to do an electrical installation in UK

 

[netblindpaul]

Is this an electrical installation as in buildings or are you designing and installing a piece of machinery?
If it is buildings then BS7671, if machinery EN60204-1.
There are no issues with SY at 400V if you choose the right stuff.
