Overhead Transmission Conductors

AAC is an efficient choice for overhead line installations, especially when design requirements do not require the higher strength or temperature ratings offered by ACSR (Aluminum Conductor Steel Reinforced), ACSS (Aluminum Conductor Steel Supported), or other conductors. Due to their lighter weight, AAC conductors result in lower costs per length and make installation easier, thereby enhancing productivity. Additionally, the simplicity of their fittings enhances efficiency. With their uniform design and all-aluminum construction, AAC conductors are naturally corrosion-resistant, enhancing their overall effectiveness.

AAAC is a reliable solution for overhead distribution and transmission lines, especially in coastal areas where corrosion can be an issue for the steel components in ACSR (Aluminum Conductor Steel Reinforced) constructions. By using AAAC conductors instead of single-layer ACSR conductors (ranging from #6 to #4/0 AWG), we can significantly reduce power losses in these lines. Additionally, the absence of a steel core in AAAC conductors eliminates the inductive effects associated with ACSR, ensuring reliable and efficient performance.

ACSR is widely used for overhead distribution and transmission lines. ACSR conductors are known for their cost-effectiveness, reliability, and favorable strength-to-weight ratio, making them a dependable choice. They combine the lightweight and good conductivity of aluminum with the high tensile strength and durability of steel. Their design allows higher tension, reduced sag, and, most notably, longer spans than most other types of overhead conductors.

ACSS is an effective solution for overhead transmission lines, addressing a range of challenges. It is particularly beneficial for reconditioning applications that require increased current while maintaining existing tensions and clearances. Additionally, ACSS is advantageous for new line applications, as it enables structural optimization by reducing sag. This technology is also suitable for new lines that must handle high emergency loadings and for lines affected by aeolian vibration.

T-2® twisted pair conductors are designed for use in overhead distribution and transmission lines that are susceptible to damage from wind-induced motion. They are available in two designs: all-aluminum (AAC/T-2) and aluminum conductor steel-reinforced (ACSR/T-2). These options effectively eliminate galloping, reduce aeolian vibration, and control conductor oscillation.

TW conductors, featuring trapezoidal aluminum strands, are designed to ensure maximum efficiency and reliability. The unique shape of these strands creates a smooth outer surface and enables a more compact alignment. This enables the construction of a conductor that either maintains the same aluminum cross-sectional area while reducing the overall diameter or retains the same overall diameter while increasing the aluminum cross-sectional area. This efficiency is further demonstrated by the conductor's reduced overall diameter, which reduces ice and wind loads. By maintaining the same diameter and increasing the aluminum content, we reduce power loss during day-to-day operations, resulting in a higher overall ampacity rating for the conductor and enhanced reliability for your electrical infrastructure.

ACSR/SD conductors are used for overhead transmission lines to control aeolian vibration. These conductors consist of a steel core surrounded by two layers of trapezoidal-shaped aluminum wires. The design includes a space between the core and the aluminum layers, which provides self-damping characteristics and eliminates the need for additional vibration dampers.

ACAR conductors are specifically designed for overhead distribution and transmission lines. These conductors are made entirely of aluminum but offer greater strength and longer spans compared to AAC conductors. ACAR cables offer high current-carrying capacity and enhanced strength while being lighter than other conductors.
