Final answer:
The wire code identification system does not convey information about the wire's insulation material. It includes the wire's gauge, voltage rating, and temperature rating. High-voltage power lines are not wrapped in insulating material but held aloft by insulating connectors.
Step-by-step explanation:
The information not conveyed by the wire code identification system is the wire's insulation material. The wire code system typically includes the wire's gauge, voltage rating, and temperature rating. The gauge of a wire is a measure of its diameter, with higher gauge numbers indicating thinner wires. This affects the wire's current-carrying capacity, with larger diameters having greater capacity. The American Wire Gauge (AWG) is a standardized system used in the United States. Wire insulation is important but is not specified by the wire gauge system. Resistance and resistivity of a wire are affected by the wire's material, length, and cross-sectional area, but not directly by the wire code identification system. High-voltage power lines are indeed held aloft by insulating connectors, but contrary to what might be implied by the question, these wires themselves are not insulated; they are bare and rely on air and distance for insulation. Therefore, the statement concerning high-voltage wires being wrapped in insulating material is false.
