Buy 100' 30awg, silver or silver plated wire, ceramic plug's. Cut 90 wires of desired lenght. 30 wires place paralel (no twisting) inside heatshrink. Do the same with L and N(30 for L and 30 for N separate of course). Place all three heatshrinked wires inside larger heatshrink, conect to the plugs, and you are going to have as good as cord as any on the market!
