Zhenglan Expands Oxygen-Free Copper PVC Insulated Cable Series with 15 New Low Voltage Models

We are pleased to announce a major expansion of our PVC insulated cable portfolio. Following strong global demand, we have added 15 new low voltage cable models, all built around our signature 99.99% oxygen-free copper (OFC) conductor and high-grade PVC insulation. This brings our current PVC insulated cable range to a total of 15 newly released SKUs covering building wire, power cable, armoured cable and control cable.

Why Oxygen-Free Copper Matters

Oxygen-free copper is produced through a deoxidation process that removes almost all oxygen from the copper, resulting in a conductor with higher conductivity, lower DC resistance and far better resistance to embrittlement than ordinary recycled copper. For buyers of low voltage cables, this means lower energy loss, more stable power transmission and longer service life — a decisive advantage in projects where performance and safety cannot be compromised.

New Models at a Glance

Key Highlights of the New Range

• 99.99% oxygen-free copper conductor for high conductivity and low power loss.
• Premium PVC insulation and sheath with excellent dielectric strength and moisture protection.
• Rated voltage 0.6/1kV, 450/750V and 300/500V to suit building, industrial and underground applications.
• Armoured options (SWA / STA) for direct burial and mechanically demanding environments.
• Shielded control cables for anti-interference signal transmission.
• Full compliance with IEC and GB standards, with CE, RoHS and ISO 9001 certification available.

OEM and Customization Support

In addition to standard stock models, we offer complete OEM and ODM services. Customers can specify conductor size, number of cores, sheath colour, printing and packaging. Our in-house R&D and QC teams ensure every cable meets the required standard before shipment, and our production capacity exceeds 500,000 meters per month to support large and repeat orders.

Reliable Global Supply

Our cables are exported to more than 40 countries across Asia, Africa, the Middle East, Europe and South America. With a stable raw material supply chain and rigorous testing on every batch, we help importers, distributors and contractors shorten lead times and reduce procurement risk. Bulk orders, mixed containers and private-label programmes are all available to match your market.
