Single-Core Copper Wire OEM Service

Single-core copper wire is a true workhorse in electrical systems across industries, thanks to its top-notch conductivity, heat resistance, and long-lasting performance. But let's be honest-off-the-shelf cables rarely tick all your boxes, whether you're wiring a data center, building industrial gear, or supplying residential electrical parts.

At Zhejiang Zhongjing Cable Co., Ltd., we've spent 15 years getting really good at one thing: making single-core copper wires that are exactly what you need. No generic, one-size-fits-all stuff here. Every wire we make is tailored to your technical specs, the local rules of your target market, and what your business needs to grow.

We work with all kinds of clients worldwide-from small businesses testing new products to big EPC firms handling massive utility projects. Got a specific need? Like ultra-thin conductors for precision gadgets or corrosion-proof coatings for marine use? We'll turn that need into a high-quality cable that helps you stand out from the crowd.

The conductor is the heart of any single-core copper wire, and we never cut corners here. You call the shots on every detail:

• Copper Type: Need super-low resistance for sensitive electronics? Go with 99.99% pure oxygen-free copper. Worried about rust in damp or industrial spots? Tin-coated copper has your back. For everyday power transmission-think home wiring or office grids-high-conductivity electrolytic copper is affordable and gets the job done.
• Structure & Size: Solid cores are great for straight runs, like wiring inside walls. If you need flexibility-for robots or car wiring-fine-stranded wires bend easily. Sizes range from tiny 0.08mm² up to 240mm², so we've got every scenario covered.
• Insulation & Protection: Pick the right covering for where the wire will live. PVC is budget-friendly for home appliances. XLPE handles heat up to 125°C-ideal for engine bays or solar setups. PTFE resists chemicals, making it a must for factories or oil rigs. For busy places like airports or schools, LSZHis safer. Add flame-retardant layers for risky areas or UV-resistant covers for outdoor use to make them last longer.

A great product deserves to look like yours. We help turn your wires into moving billboards for your brand:

• Cable Branding: We'll laser-print your logo, product code, voltage, or certifications right onto the wire's cover. It's scratch-proof, so your brand stays visible even after years of use.
• Packaging That Works for You: Choose from branded reels or coils-we'll print your company name, logo, and contact info clearly. Need labels in multiple languages? No problem-English, Spanish, German, Arabic, Hindi, Thai… whatever your market speaks. We'll also throw in a custom installation guide with safety tips for your region, so your customers have an easier time using your products.

We know how stressful it is when a great product gets held up by certifications. That's why we handle compliance from day one:

1. Global Standards: Our wires meet tough international rules like IEC 60228, UL 1581, VDE 0295, BS 6346, AS/NZS 3000, and BIS-so you know they're quality.
2. Local Rules: Whether it's the EU's RoHS/REACH, California's Prop 65, Saudi Arabia's SASO, or Thailand's TIS, we make sure your wires check all the boxes. No extra work for you to adjust to local laws.
3. Paperwork Ready to Go: Every order comes with full test reports and certification copies. They're ready for project approvals, customer checks, or customs-no delays, no hassle.

Tell us what you need: where the wire will be used, your target market, specs like size or insulation, and how you want your brand to look. We'll handle the rest.

We're more than just a manufacturer-we're your partner in making cables that help your business win.
