Embodiment 1
[0021] A parallel bundled wire, comprising a single wire composed of a conductor and an insulating outer layer wrapped around it, and the single wires are bonded to each other through the surface of the insulating outer layer and arranged in parallel in a straight line;
[0022] The conductor is an aluminum alloy carbon fiber composite conductor, which is prepared according to the following method:
[0023] Step 1) Put the graphite into a crucible, place it in a muffle furnace for calcination, and under the protection of nitrogen, calcine at 700°C for 3 minutes, take it out, crush it into powder, and obtain modified graphite;
[0024] Step 2) Add modified graphite, carbon fiber, and nano-silica (particle size: 50nm) to the high-speed stirrer in turn, stir for 5 minutes at 1000 rpm, then preheat to 100°C, let stand for 5 minutes, and then immerse in the double In the phenol A type epoxy resin, the modified carbon fiber is obtained by pulling it out in the form of strands throug...
