High-Purity Copper for Best Conductivity

Our factory produces the copper conductor cable as a general-purpose cable with high-purity copper conductors. This product works for power transmission, control circuits, and signal transmission. The product uses high-quality annealed or tinned copper conductors. It has electron-beam cross-linked LSZH polyolefin or PVC insulation and sheath. The copper in our product has a conductivity of 100% IACS and low resistivity. This gives very high power transmission efficiency. The product works from -40°C to +90°C. Our product is the best choice for low-loss electrical systems.

Oxygen-Free Copper and Anti-Corrosion Options

The copper conductor cable has three key strengths. First, the conductor uses oxygen-free copper with a copper content of over 99.95%. This gives the product excellent conductivity. Compared to aluminum, it greatly reduces line loss. Second, the conductor can be tinned on request. This protects the product from oxidation in high-temperature and humid environments. Third, we offer a very wide range of products. The product covers everything from control cables to power cables for one-stop shopping. Every product passes 100% conductor resistance and hi-pot tests. More than 300 partners trust our product.

Applications and Conductor Selection Guide

The copper conductor cable is used for power, control, and equipment connections. In solar farms, it works for high-current transmission from combiner boxes to inverters. It also handles inverter control signals. In distribution systems, the product connects main circuits between panels. In industrial equipment, it supplies power to motors, VFDs, and control cabinets. The copper conductor cable also fits building electrical, rail transit, and telecom base stations. Tinned copper is better for high-temperature, high-humidity, and coastal salt-spray environments. Bare copper is cheaper and works well for dry indoor areas. The same copper cross section carries about 1.3 times the current of aluminum. Copper also has lower contact resistance. This means lower long-term losses and better life-cycle cost. We offer custom conductor type, insulation/sheath material, cross section and core count, cutting, and printing. We can make it to GB, IEC, UL, and BS standards. We hold ISO 9001, ISO 14001, and ISO 45001. The lead time is 15 days after deposit.
