Mistletoe 556MCM, Electrical Wire Roll Surplus, 21.72 mm Dia, 0.743 kg/M Weight, 74.7 kN Breaking Strength

The Mistletoe 556MCM All Aluminum Conductor (AAC) is a bare overhead transmission cable. It features 19 concentrically-lay-stranded aluminum conductors, typically conforming to ASTM B231 for aluminum 1350-H19 wire. This conductor type has a nominal cross-sectional area of 556,000 circular mils. Each of the 19 strands typically measures 0.171 inches in diameter, resulting in an approximate overall cable diameter of 0.855 inches (21.72 mm). The nominal weight of the cable is approximately 0.499 pounds per foot (0.743 kg/m). Electrical characteristics include a DC resistance of approximately 0.0933 ohms per 1000 feet (0.306 ohms/km) at 20°C. The rated breaking strength is typically 16,800 pounds (74.7 kN).
