“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.”

Key Features & Benefits: 2/0 Stranded Tinned Bare Copper Wire

• 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.
