I am designing a cable reel for a mining application the voltage is 1000V AC and the current is 360 Amp and I am looking for a design for a slipring contact. The rotation is bidirectional. The rotating speed is very low about 1 rotation per hour. I could not find what I am looking for on Google maybe someone can give me some pointers. I have in mind a brass or bronze ring of 250mm diameter and 40mm wide with Tufnol dividers and spacers. Would a brass wiper contact be acceptable? For the spring action I am considering copper leaves.
