Description
Product Overview
The CHIYODA EcoFlex Series is the Budget option for industrial electrical transmission, engineered specifically for high-amperage secondary voltage connections from welding power sources to torches, holders, and ground clamps. Built with 100% pure plain annealed copper, this professional-grade cable delivers maximum electrical conductivity to ensure a stable, highly efficient arc during rigorous fabrication applications.
Beyond standard metalworking, CHIYODA EcoFlex cables are globally sought after for alternative high-power applications—including battery banks, solar arrays, power inverter wiring, and marine audio installations—thanks to their legendary mechanical durability and extreme bending flexibility.
Core Performance Advantages & Selling Points
-
100% Pure Copper Conductor Core: Manufactured exclusively with ultra-fine, stranded plain annealed copper wire to transmit high current volumes efficiently with minimal voltage drop.
-
Advanced Dual-Layer Rubber Insulation: Features a unique high-dielectric Neutral Ethylene Propylene Rubber (EPR) white inner layer, paired with a rugged, wear-resistant Black Chlorosulphinated Polythene Rubber (CSPE) outer sheath.
-
Engineered for Brutal Environments: Highly resistant to dragging abrasion, oil pooling, grease, ozone degradation, severe UV exposure, and intense radiant slag heat.
-
Outstanding Mechanical Flexibility: The dense array of multi-stranded 0.19mm micro-wires ensures effortless handling, reducing hand wrist fatigue for operators manipulating heavy leads all day.
-
Strict Eco-Conscious Compliance: Fully certified and compliant with modern international environmental and safety protocols, meeting RoHS Directive 2002/95/EC, REACH standards, and CE guidelines.
