Customizable YVFB-36-19 Stranded Copper Wire with PVC Sheath - Bulk Supplier

Look, if you're running overhead lines or industrial equipement that takes a beating in tight spaces, this flat wire form factor makes a world of difference—it pulls through cable trays and conduit runs way easier than round cable of the same gauge, and PVC-on-PVC construction holds up nicely form -40°C right through to 150°C without getting brittle or gummy.

We're talking stranded copper with a 0.75mm² to 2.5mm² cross-section here, so you've got some flexibility in current carrying, and the tensile strength checks in at minimum 12.5 MPa with elongation north of 180%—that's better than a lot of commodity flat cables we see, so it won't snap on you during a tight bend instalation or if someone accidentally yanks it.

The voltage rating is either 300/500V or 450/750V depending on your exact configuration, and we usually run stock on the plum-shaped core arrangement for better flex life, but the parallel core is available too if your application prefers it—basically, just tell us your preferred color from the RAL range and we'll match it, but the dielectric strength at 18 MV/m minimum means insulation breakdown is pretty much not a concern in most industrial environments.

So the oxygen index at 26% means it won't support flame propagation easily, which matters for overhead runs in plenums or areas with fire code concerns, and we've got ISO9001, CE, and CCC certifications on file if your QC needs paperwork—thermal stability at 200°C for 50 minutes or so gives you a solid safety margin under sustained load too (usually 2-4 weeks lead time on custom colors, but we keep black and gray in stock).

One thing we've noticed handling thousands of meters of this stuff is that the 1.0×108 Ω·m volume resistivity holds steady even after repeated heating cycles—most buyers go with the standerd 300/500V rating for general industrial overhead use, though the 450/750V variant works better if you're pushing longer distances or have higher transient spikes in your circuit.

Not great for submersion application though—teh PVC sheath isn't really continuous water contact, so stick to indoor or protected outdoor runs if moisture is likely, and confirm the core arrangement you need before ordering since the moulding dies differ between parallel and plum shapes.
