    1. No, wrap the mica tape directly around the conductor and then add insulation.2. To prevent damage to the mica when the insulation is squeezed after wrapping, consider wrapping it with one layer of CV tape (two layers for NA models, one layer for NB models).3. You can wrap it with a layer of polye

    Steel tape is a ferromagnetic material. When steel tape is used for armoring single-core cables, magnetic lines of force pass through the tape during operation. Because both ends of the tape are grounded, forming a loop, current flows through it, causing the cable to heat up and reducing its current
