Frequently Asked Questions (FAQ)
Q
What is the significance of the Z-twist note at the bottom of the table?
The note states that the outermost layer of the ACSR conductor is twisted to the right (Z). This standard direction of stranding ensures compatibility with installation fittings and prevents untwisting during tensioning.
Q
How do the Code Names and Old Code Names relate to each other?
The "Old Code Names" (such as MOLE, SQUIRREL, and GOPHER) are traditional, widely recognized industry terms for specific cable sizes. The modern "Code Names" (like 11-AL1/2-ST1A) provide structured technical detail, indicating the nominal aluminum and steel area ratios.
Q
What is the relationship between conductor size and maximum electrical resistance?
As shown in the table, larger sectional areas correspond to lower electrical resistance. For example, the small "MOLE" conductor has a maximum resistance of 2.7027 Ω/km, whereas the much larger "MOOSE" conductor has a maximum resistance of only 0.0547 Ω/km.
Q
How does the steel core affect the Nominal Breaking Load of the ACSR conductor?
The galvanized steel core provides the primary mechanical tensile strength. Conductors with a higher sectional area of galvanized steel or higher steel-to-aluminum ratios generally exhibit a significantly higher Nominal Breaking Load (measured in kN).
Q
What is the difference between the aluminum and steel wire structures in these cables?
ACSR conductors consist of outer aluminum wires for high electrical conductivity wrapped around a central galvanized steel wire core for high mechanical strength. The table details both the diameter and number of strands (No.) used for both materials in each configuration.
