From time to time I need HV shielded cable typically 50 or 70mm 1/0 2/0. Looking for more suppliers, ones that respool as I don't need that much 50-100 ft at a time.
I've made my own by buying shielding braid, and slipping it over the wire or cable as needed. For example www.wireandcableyourway.com/belden-8669-8-9-awg-hook-up-wire-braided-tinned-copper is 0.5" diameter. Various sizes are available from wire suppliers like Belden.
If it's big enough, you can strip scrap/surplus RF transmitting coax cable (RG-8, RG-11, RG-58, RG-59 etc.) and slide its braided shield over your own cables. You need the /U version with a braided copper shield; cheap TV coax only has a foil shield and won't work.
You can wrap thick wires or cable bundles with aluminum or copper foil. Companies like www.tapejungle.com/categories/foil-tape.html sell copper adhesive tape that is good for this purpose.
Finally, you can route your cables in metal conduit. I did this on my LeCar EV for the 2/0 cables that run under the car between the front and rear battery boxes. It provides both shielding and protection from road debris.
If you do a good enough job with your shielding, even the AM radio will work! :-)
