556.5 MCM Parakeet ACSR TP Aluminum Conductor Steel Reinforced Twisted Pair

Application:

ACSR/TP conductors utilizing AcuTech2 technology. This twisted pair technology allows our product to protect against the effect of aeolian vibration and ice galloping to which many transmission and distribution projects are exposed.

Also Known As:

556.5 MCM ACSR TP Aluminum Cable, 556.5 MCM Aluminum Reinforced Cable, Steel Reinforced Cable, 556.5 MCM ACSR TP Cable, Aluminum Twisted Pair Cable, 556.5 MCM ACSR TP Aluminum Conductors.

Features:

• ACSR/TP has developed into a preferred solution for utilities in regions where wind-induced problems such as aeolian vibration and galloping regularly prove to be detrimental to the integrity of their overhead transmission and distribution systems. The varying diameter of the twisted conductor facing the wind helps prevent buildup of resonant vibration in the line, and its figure 8 shape offers low torsional stiffness, which helps to mitigate the effect of motion-causing wind forces on the conductor.
• In addition, ACSR/TP conductors permit higher line tensions, which help reduce line costs by permitting lower sag and/ or longer spans. ACSR/TP has a lower ac resistance than a single conventional conductor with the same aluminum area, which means that ACSR/TP operates at lower temperatures. Another advantage offered by ACSR/TP is its compact design that can help optimize right-of-way costs for utilities. Finally, conventional tools used for ACSR conductors are also suitable for ACSR/TP products.

Construction:

• ACSR/TP consists of two ACSR conductors with long lay lengths twisted around each other. Class A zinc coating (ACSR/TP/GA2) is usually adequate for ordinary environments to protect the steel core wires from corrosion.
• ASTM referenced specifications include B230, B232, B498, B500, B606, B802, B803 and B911.
