70mm SWA Cable Support

[gtownspark]

Hi Guys

I need to cleat a 70mm 4core SWA cable along a 180m run in a tunnel below a castle to a new plant room, does anyone know what cable manufacturers recommend for spacing of cleats?

Table 4A onsite guide.page113. 450mm horizontally 600mm vertically. Cables over 40mm then manufacturers recommendation. I expect you have already come to this
conclusion?

Yeah I've already check my OSG but I don't know any cable manufacturers to contact today, so was hoping someone might already have an idea on the manufacturers recommendations.

try AEI cables.

According to Eland.co.uk. for 70mmm SWA 4 core the overall cable size is 37.7mm.

You'll get little to no cable sag on that 70mm cable with fixing spacings of 400 to 450mm on the horizontal plane...

Is it worth installing containment now in order to 'future proof' the cable run??

Just a thought.

Thanks guys, I spoke to the electric cable company in Peterborough in the end and they recommend 500mm spacing....360 cleats are on order!
