If you're looking for a balance between high electrical conductivity and mechanical strength, you've come to the right place. Learn about the aluminum conductor steel-supported/trapezoidal wire available at Peak Substation Services.
Applications of Steel Reinforced ACSS/TW Wire
The aluminum conductor steel-supported trapezoidal wire is specifically engineered for overhead distribution and transmission lines. It has excellent tensile strength and can work continuously up to 250 ºC. In addition, the cable exhibits reduced sag under emergency electrical loads and boasts superior self-damping characteristics. It's also immune to long-term aluminum creep effects.
This cable is available as an equal-area and equal-diameter conductor. This means you can go for the equivalent ampacity in a smaller conductor diameter or increased ampacity in an equal-diameter conductor.
The wire also provides numerous design benefits for new line construction. These include reduced tower costs, decreased sag, and excellent self-damping properties. Moreover, the cable is corrosion-resistant and applicable in coastal areas with saline conditions. It also works with a higher operating temperature.

Specifications of the ACSS/TW Wire
This popular conductor coincides with or exceeds these ASTM specifications:
ACSS/TW Construction
The ACSS trapezoidal wire is characterized by a concentric-lay-stranded design. Its central core consists of steel strands encircled by one or more layers of aluminum 1350-0 wire with a minimum average conductivity of 63 percent.
The steel core primarily handles the conductor's mechanical load due to the soft or fully annealed tempered aluminum wire. Safeguarding the steel core against corrosion is the zinc-5 percent aluminum-mischmetal alloy layer. Peak Substation Services also offers variants like high-strength, aluminum-clad steel core and aluminized steel core.
ACSS/TW Features
There isn't much difference between the ACSS/TW wire and the conventional ACSR/TW conductors. However, the former has an edge in several ways.
First, ACSS TW cables incorporate a zinc-5% aluminum mischmetal alloy coating. This allows them to reach operating temperatures up to 250 °C. In addition, the cable's minimum average conductivity is 63 percent International Annealed Copper Standard (IACS) for their annealed 1350-O aluminum wire, which improves their current carrying capacity.
The design of ACSS/TW wire places little to no mechanical load on the annealed aluminum wire, which minimizes the impact of aeolian vibration. With ACSS/TW wire, you don't have to worry about long-term creep, and the equal area design delivers equal ampacity with about 10 percent less diameter.
At the same time, the smaller diameter reduces the effect of emergency electrical loadings. You can opt for an equal-diameter conductor, increasing aluminum area by approximately 20 to 25 percent. This will lower the AC resistance by about 15 to 20 percent and enhance its current-carrying capacity by about 10 percent.

ACSS TW incorporates a steel-reinforced stranded steel core with a metallic coating. The core provides mechanical support, while the corrosion-resistant coating maintains its integrity.
This conductor features an electrical aluminum 1350 round wire. It's annealed (heat-treated) and can have intermediate tempers.
The cable has a coated steel-supported Zinc-5% Aluminum-Mischmetal alloy for aluminum conductors.
ACSS/TW uses a steel-reinforced high-strength steel core coated with the Zinc-5% Aluminum-Mischmetal alloy for aluminum and aluminum alloy (aluminum-clad steel).
ACSS TW is a compact concentric-lay-stranded aluminum with a coated steel-supported core.
A cable's size determines its current-carrying capacity and resistance. Choose larger options like Santee and Powder (2627.3 kcmil and 2153.8 kcmil, respectively) if you intend to carry more electrical current and minimize power loss. On the other hand, the smallest varieties are Linnet and Oriole, each 336.4 kcal.
The right cross-sectional area means the wire can efficiently transport the electrical load without voltage drop or overheating. Santee boasts the largest cross-sectional area at 2.2268 in², meaning it has better material conductivity and higher ampacity than Linnet, which has 0.307 in².
You also want to consider the wire's mechanical integrity and ability to withstand stresses like tension and wind loads. The standard, high, and extra-high strength stats are indicated on the specific product descriptions, so choose one that aligns with your environment.
Compare the aluminum wire stranding to determine your cable's flexibility and mechanical durability. Generally, a wire with a lower stranding is more flexible and suitable for applications with tight bends.
