HV shielded cables -US

Post by octo27 » Jun 22 2015 12:17pm

Hello,

I'm looking to buy some high voltage shielded cables for connecting a 50kW induction machine to it's drive.

Something similar to these:

I'm having troubles in finding similar ones in the US. The ones from coroplast have infinite lead time, and I don't have that much patience :mrgreen: .

Could anyone please recommend me some cables?

Cheers,
octo

Meaning a motor/generator? What voltage/current?

Yes, meaning a motor/generator. I'm looking at 400V and 85A in a high temperature environment.

I'd rather get some thicker over-dimensioned cables and be on the safe side, especially since they will be quite short.

Thanks!

Here's one example, this stuff is recommended by Rinehart Motion Systems.

However, I don't know of any suppliers that will sell it by the foot, you may have to buy a whole drum of it.

Let us know if you do find some.

Maybe tell us some more about your application, but you could do a makeshift version by slipping a braided screen over regular cable, then something like heatshrink to hold it in place.

Grinhill,

Thanks for the reply. The link is promising. I'll contact the company and let you know how it goes.

A makeshift cable wouldn't be adequate for a high temperature environment.
