SY Cable? Thoughts?

[cliffed]

Seen so much of it used,it’s easy to install,I personally don’t like it.
It’s something that’s happened over the years,all because of fast fix,cost issues I presume.
In my day it was either Swa,trunking,conduit,flexible conduits,the skill of sparkies slowly being put to the bottom of the ladder.

Are you saying you have SY in a constant flexing motion on a machine here or am I reading this wrong?
You are also saying you install a pvc outer sheath cable in an environment where it is subject to oil?

The difference I would suggest is a cable flexing 1000 - 10,000 times before breakdown and 10million and also a pvc degrading within 2-5 yrs or lasting 20yrs subject to and nature of the chemical oils.

Are you providing a machine that requires costly services every few yrs after warranty of a machine runs out or one that will last, trust me I know the difference just from a visual inspection.

Yes, to the first part, your right it does get damaged tbefore other cables.
All the machines mentioned have been bought with SY, we haven’t put it in, only replaced like for like.
The rotating part I mentioned was the rotating platform contain the nip rollers way above a fiom extrusion machine. The platform rotates slightly more than 360 degrees, but due to some clever mechanical linkages, the cable only travels 180 degrees. The atmosphere up there is very hot and greasy from the plastic.

I run it in Unistrut quite a lot. No particular reason!

I think for mechanical strength it can’t be beaten.
The way it attaches to its special glands makes it very strong. I use it for power leads on portable machinery, people tend to try and more machines with unplugging them, which of course would pull cab.emour of a normal gland.

Do you happen to know how much the orange (or is it green?) Rexroth Indramat cable is?
