Plate Brazed

Do you have an idea on how to make this work?
I'm trying to build a homemade wind turbine and I'm going to have the turbine itself on a 1-1/4" galvanized pipe as the mast on top of a 50' lattice tower. I'm wanting to be able to run the power cable down the pipe to the pivot point to avoid chaffing of the wire on the tower as it turns in the wind. What I had planned on doing was brazing a bearing to the bottom of the pipe and the bearing would be attached to a plate about 3' down inside the lattice tower. From there the wire would pass through the bearing pivot point and would pass through support rings every so often down the tower to keep it from flopping around in the wind but keeping it free to twist with the turbine. When I tried to do the brazing the bearing burned up before it was ever hot enough to melt the braze. Any ideas on how to make this or something similar work? Any ideas or thoughts would be greatly appreciated! Thanks for your time.
There are swivel type connectors available. I would run the cable down the center inside the pipe. That takes the wind out of the picture. Then, mount the swivel connector near the base of the pipe, and run the rest down the center of tower. The swivel connector is a 360 degree sliding contact type connector, and would be perfect for your application.
