Someone’s running overhead lines for a temporary indutrial setup or outdoor lighting string, and they need conductor that won’t go brittle in -40°C or soften at 150°C—that’s where this RVV-53-7 fits, basically a flat PVC-sheathed stranded copper cable with low-smoke zero-halogen jacket.
We’ve got it in 0.75mm² up to 2.5mm² cross-section, usually 300/500V or 450/750V rating depending on what you tell us, and core arrangement can be parallel or plum shape—teh plum shape actually sits flatter against a pole or conduit, so installers tend to prefer it for overhead runs.
Tensile strength is ≥12.5 MPa with elongation at break ≥180%, which means it’ll take a fair bit of pulling without snapping, and volume resistivity holds at ≥1.0×10⁸ Ω·m at 20°C; dielectric strength is ≥18 MV/m, so you’re not worrying about arcing in damp conditions.
Bulk pricing kicks in around 500 meters or so—typical MOQ for custom colors or strand counts is 1000 meters, and lead time is usually 15-20 working days unless our company have stock, which we often do on black and white jackets. Most buyers ask about oxygen index—it’s ≥26%, so it passes most fire codes for indoor-outdoor transitions.
Also, it’s certified ISO9001, CE, and CCC, but we don’t ship this for direct burial or continuous submersion—the PVC sheath is tough but not wet environments long-term. Shore hardness is 65±3 A, so it’s flexible enough to coil on a drum but won’t kink easily.
Our MOQ is 1000 meters, but we can adjust the length per your project needs—just let us know the exact meterage when you order.
Yes, we include all three certifications—ISO9001, CE, and CCC—with every batch. Just request them in your order, and we'll attach the copies.
Standard lead time is 7-15 days after deposit. If you need it faster, we can prioritize production for a small surcharge—contact us for details.
Yes, it's designed for overhead applications. The LSOH rating means it emits low smoke and no halogens when burned, which is key for safety in enclosed or populated areas.
Absolutely. You can choose any color or adjust the strand count within the 0.75mm² to 2.5mm² cross-section range. No extra charge for standard options, but custom colors may need a larger minimum run.
