The PVC inner sheath of YCY cushions the cores, keeps the braid round so its coverage stays uniform, and adds a second barrier against moisture and chemicals.<\/p><div class=\"svg\"><svg

Keep the braid continuous up to the gland; do not open it further than necessary.\n3. Segregate screened control cables from unscreened power cables on trays, or use a metal divider.\n4.
