Tuling’s Copper Terminal Connectors
At Tuling, the copper grade we use to produce our copper terminal connectors has a minimum conductivity of 100% IACS which provides excellent conductivity. We manufacture our copper terminal Connectors with tin, nickel or other corrosion-resistant coating to meet ASTM B33 standards to make them super corrosion-resistant. We use heat-resistant thermoplastic insulation so our terminal connectors can operate at 105°C (221°F) temperatures.
Tuling fabricated most of the copper terminal connectors on customer request and specification with versatile options of sizes, configurations and terminal types.
