19×0.25mm Tinned Copper Alloy Wire - Durable Grounding Wire is built to provide reliable performance in heavy-duty grounding and bonding applications. Composed of nineteen strands of 0.25mm fine tinned copper alloy wires, it offers enhanced flexibility, excellent corrosion resistance, and superior mechanical strength, ensuring stable conductivity and long-term reliability even in harsh environments.
This robust wire structure makes it ideal for use in electrical grounding systems, industrial equipment bonding, and protective earthing solutions.
19×0.25mm stranded structure ensures durability and high-current carrying capacity
Tinned surface resists oxidation and facilitates strong, consistent soldering
High mechanical strength supports rugged use and environmental stress resistance
Excellent flexibility allows easy installation in complex grounding layouts
Customizable strand counts, diameters, and spool sizes for industrial-scale projects
Grounding and earthing cables for industrial and commercial electrical systems
Bonding straps for equipment chassis and protective earthing solutions
Heavy-duty grounding networks in renewable energy installations
Shielding grounds in telecommunications and data center wiring
Automotive and marine grounding applications in high-humidity environments
