Frequently Asked Questions

What is the standard compliance for AAC conductors?

These AAC (All Aluminum Conductor) products are manufactured and tested in accordance with the IEC 61089 international standard, ensuring high quality and reliability for overhead power transmission.

What are the advantages of using Type A1 AAC?

Type A1 aluminum conductors offer an excellent strength-to-weight ratio, high conductivity, and superior corrosion resistance, making them ideal for urban and coastal power distribution.

What does the "Z" twist direction signify?

The "Z" twist indicates that the outermost layer of the stranded aluminum wires is twisted to the right. This is a standard engineering specification for conductor stability and compatibility with fittings.

How is the maximum resistance calculated?

The maximum resistance is measured at a reference temperature of 20°C. It determines the electrical efficiency of the conductor; lower resistance leads to lower energy losses during transmission.

Why is Nominal Breaking Load (kN) important?

The Nominal Breaking Load indicates the maximum tensile force the conductor can withstand before failure, which is critical for calculating safety factors in line tension and sag designs.

Can AAC conductors be used for long-span transmission?

AAC is primarily used for relatively short spans in distribution lines. For very long spans requiring higher mechanical tension, conductors like ACSR (Aluminum Conductor Steel Reinforced) are typically preferred.
