We're actually going with the YH model welding cable for the machine tool line and motor assembly stations, and the main reason is the custom color and size options—our company can get it in orange or custom, and they'll do 4/0 AWG or 70mm² without a minimum that kills us.
The 450/750V rating is fine for our welding machines, and the conductor resistance runs from 0.17 to 1.91 Ω/km depending on size, which is tighter than most generic cables we've tested, and that matters for consistent arc stability at the tool end.
We usually have stock on the common sizes like 2/0 and 50mm², but if you need the 120mm² version, confirm lead time—it's typically 20 days or so, and the 259 to 2146 strand count gives it that flexibility we need for tight cable trays.
For the trust side, they've got ISO, CCC, CE, and VDE certs, and the ASTM/IEC60245 standdard is what we've been using for years anyway, so the compliance paperwork is already locked in with our quality team.
One thing—these cables aren't great for continuous flexing in robotic arms; the rubber insulation (EPDM/CPE sheath) handles -20°C to 90°C fine, but the stranding is more about current capacity than cycle life, so keep that in mind for any moving parts.
Also, the current rating varies form 165 to 496A by size, but we're ordering the 3/0 AWG for the main feed, and the 25mm² for teh smaller tools, and they'll do custom lengths with no upcharge on the cut fee.
The YH cable is ISO, CCC, CE, and VDE certified, meeting ASTM/IEC60245 standards. All certifications are internationally recognized, so you can use them for export without issues.
Yes, we offer custom colors besides the standard red, black, and orange. The MOQ for custom colors is typically 500 meters, but we can discuss it based on your needs.
Lead time for 1000 meters of 4/0 AWG is usually 10-15 working days after order confirmation. If you need it faster, we can prioritize production for an additional fee.
You can choose either pure copper or aluminum alloy. Pure copper gives lower conductor resistance (down to 0.17 Ω/km) and higher current rating (up to 496A), while aluminum alloy is lighter and more cost-effective.
Store it in a cool, dry place away from direct sunlight, ideally at temperatures between -10°C and 40°C. This keeps the rubber and EPDM/CPE sheath in good condition for the rated -20°C to 90°C range.
