Frequently Asked Questions (FAQ)
What is the difference between Nominal Area and Total Sectional Area?
Nominal Area is a simplified standard designator used for naming and identifying the conductor size. The Total Sectional Area is the precise mathematical sum of the cross-sectional areas of both the aluminum alloy strands and the reinforcing steel strands.
How does the steel core composition affect the Rated Strength of the conductor?
The steel core acts as the primary load-bearing element. Higher ratios of steel sectional area to aluminum alloy sectional area significantly increase the Rated Strength (measured in kN), making the conductor suitable for longer spans and high-tension installations.
Why is the Max D.C. Resistance specified at exactly 20℃?
Electrical resistance changes with temperature. 20℃ is the standard reference temperature used globally in electrical engineering to allow consistent, standardized performance comparison between different conductor designs and materials.
What is the significance of the stranding configuration (e.g., 54 Al / 7 Steel)?
The stranding configuration determines the flexibility, overall diameter, and mechanical behavior of the conductor. More strands generally offer better flexibility and resistance to fatigue caused by vibration, while fewer strands might offer a smaller overall diameter.
How does Linear Mass relate to shipping and installation?
Linear Mass (kg/km) indicates the weight of the cable per unit length. This value is critical for calculating logistics costs, reel capacities, sag tensions, and structural tower loading limits during overhead transmission line design.
