We're talking about a Class 5 stranded bare copper cable here, 10 to 240mm² cross-section, with EPDM rubber insulation and jacket — it handles -40°C to +90°C continuous, max conductor temp hits +120°C, and the test votage is 1.0 KV, so it's built for heavy welding arcs without breaking down.

Most buyers in shipbuilding or automotive use it for connections between welding generators and hand-electrodes or workpieces, but we've also seen it on conveyor systems and welding robots, though it's not really suited for fixed installation in wet trenches — the rubber jacket is tough but not submersible.

We usually have stock on the common sizes like 35mm² and 50mm² in black or red, but custom colors take about 20 days or so — MOQ is typically 1000 meters per size, and we can do 500m coils or 1000m drums, whichever your warehouse prefers (check lead time on the 10mm², that one moves fast).
For documentation, every shipment comes with a COA from our in-house lab, plus third-party HPLC results if you need them — we've got ISO, CCC, CE, RoHS, and VDE certs on file, so you can send those straight to your compliance team without chasing us for paperwork.

Payment terms are T/T with 30% deposit and 70% against the BL copy, but for repeat orders over $50k or so our company can discuss a letter of credit — shippng form Shanghai takes about 25-30 days FOB, and we'll send you the packing list and SDS along with the invoice.

Actually, one thing buyers don't always ask: the EPDM insulation holds up better than PVC in ozone-heavy shop floors, so if you're running multiple welders in tight spaces, you'll get less cracking over time — it's a small detail but saves on replacements.
You can get it from 10mm² up to 240mm². We stock the common sizes, but if you need something in between, just ask.
It's certified ISO, CCC, CE, RoHS, and VDE, so you're covered for both domestic and international industrial use.
Yes, we offer black and red as standard, but we can match your custom color if you order a minimum quantity. Just let us know the shade.
For standard sizes and colors, we usually ship within 2-3 weeks. Custom colors or larger sections may take 4-6 weeks, depending on the order volume.
Absolutely, it's rated from -40°C to +90°C, with the conductor handling up to +120°C. The EPDM rubber also resists abrasion and keeps its flexibility in cold conditions.
