"Designed for overhead electrical transmission, distribution, and grounding systems where high conductivity, flexibility, and corrosion resistance are required, 2/0 Stranded Tinned Bare Copper Wire delivers long-lasting performance in demanding environments. Manufactured using soft temper stranded tin-coated copper conductors (hot dipped or electroplated with tin), this wire significantly improves resistance against oxidation and corrosion. Built in a 19-strand construction, it provides exceptional flexibility for grounding electrical systems, substation grids, and utility applications."
Corrosion-Resistant Tin Coating: Hot dipped or electroplated tin coating significantly improves resistance to corrosion, moisture, and oxidation.
Soft Temper Stranded Copper: Soft drawn (annealed) copper conductor provides high conductivity and excellent flexibility for grounding applications.
19-Strand Flexibility: Concentric-lay stranded design with 19 individual strands ensures smooth bending and handling during installation.
High-Conductivity Grounding: 2/0 AWG cross-sectional area offers low DC resistance (0.07949 Ohms/1000 ft) for overhead distribution and electrical system grounding.
Cut-to-Length Availability: Available cut by the foot to fit exact job requirements or on bulk reels for large utility projects.

2/0 Tinned Copper Wire is primarily used for heavy-duty grounding grids, bonding main service equipment, lightning protection, and direct-burial grounding loops where resistance to moisture and soil corrosion is critical.
The tin coating acts as a protective barrier against oxidation, corrosion, and chemical exposure, significantly extending the wire's lifespan in wet, underground, or outdoor environments without sacrificing electrical conductivity.
Yes. Because it is manufactured with soft-drawn (annealed) copper and stranded in a Class B 19-strand configuration, it bends much more easily than hard-drawn or solid conductors during installation.
Wire America supplies a broad inventory of tinned bare copper grounding conductors available cut by the foot or on master spools. Orders are typically processed and shipped within 1 to 2 business days, delivering directly to your shop or job site within 2 to 4 business days once in transit.
We ship your order from the closest regional distribution hub to your job site to keep transit times and freight costs as low as possible. Expedited shipping options are also available at checkout.
