Core Advantages of Copper Power Cables and Wires
-
Exceptional Conductivity: Reaching 58 MS/m per the International Annealed Copper Standard, copper boasts conductivity 1.6 times higher than aluminum with 40% lower electrical resistance. It allows either smaller conductor sizes to save space or greater current carrying capacity at the same cross-section, effectively cutting energy loss during long-distance power transmission.
-
Superior Mechanical Performance: It features high tensile strength, outstanding ductility and excellent bending resistance. It avoids damage during installation, maintains stable contact resistance at joints, and ensures a service life of more than 30 years.
-
Excellent Corrosion Resistance: With a low oxidation rate, copper adapts perfectly to humid, acidic and alkaline environments. It is well-suited for underground, marine and chemical industry scenarios and requires minimal routine maintenance.
-
High Safety and Reliability: It possesses good thermal stability and strong overload capacity to lower fire hazards, guaranteeing steady power supply for precision devices and key facilities.
-
Easy Installation: Optimized flexibility facilitates bending, cutting and terminal connection, boosting construction efficiency and reducing overall installation costs.
