Aluminum Conductor Steel Supported Electric Cable
Electrical cables come in different types and sizes manufactured for different services. But one thing for sure is that they all have the capacity to transmit electric current, but the consistencies of the service varies from one cable to another. At Nassau Electricals we have a wide range of cables to cover same similar needs but we never compromise on quality so you can be sure of smooth power or data transmission when you opt for our products. On this post am going to share with you about an Aluminum Conductor Steel Supported (ACSS) cable. The ACSS cable is a concentric lay strand electrode which may have one or many layers of annealed and hard drawn 1350-0 of aluminum wires, all these centralized round a core of steel. For the ACSS wire and cable product, at a normal operating environmental condition the mechanical load is ofachieved from the steel core; because the aluminum when in a fully annealed stage will not contribute more on building the mechanical strength. An appropriate coating has been done on the steel core wires through the galvanization, aluminum cladding or the mischmetal alloyed coating to protect the steel core wires from corrosion.
The coating on the steel wires is selected based on the type of environment the ACSS cable will be exposed to alongside the operating temperature ratings of the conductor. ACSS wires and cables have the capacity of performing at high temperature conditions of up to 250 degrees without losing its mechanical properties; and the long term creeping of aluminum does not affect the final sagging tension performance of this cable.
Materials used in making this electric cable is tested and proven with the following Technical Standards:
• B-500 ; -a zinc aluminum mischmetal alloyed coating, a galvanized (zinc-coating) and the aluminized (aluminum
coated) core of stranded steel wire inserted for use in the Aluminum Conductor Steel Reinforced (ACSR).
• B-609; -An annealed with intermediate toughened round aluminum wires, which are suitable for use in
electrical purposes such as the stranding to conductors or the solid single electrode which can either be bare or
• B-802; -a rounded, Zn-5Al-MM alloyed coating, a steel core wire having three classes of the coating used for
the mechanical support in the manufacturing of aluminum electrodes, steel reinforced.
• B-803; -a rounded, high strength, Zn-5Al-MM alloy-coating, and a steel core wire having only one class of Zinc-
5% aluminum-mischmetal coating (MA3) used as the overhead electrical conductor.
• B-856; -a rounded wire concentrically laid and stranded aluminum conductor, steel reinforced (ACSS) for use
as an Overhead Electrical Conductor.
• B-958; -a rounded, ultra high strength and extra high strength, class A coating Zn-5Al-MM alloy-coating, steel
core wire for overhead electrical conductors.
Features of ACSS cable
• ACSS electrical cable have the ability to perform in areas of high temperatures of up to 250 degrees with no
loss of strength, as compared to ACSR which is only limited to temperatures not exceeding 100 degrees.
• The Zinc-5% aluminum – mischmetal alloy coat, helps in protecting the cable wires from corrosion. The use of
steel material also makes the cable much strong.
• This cable gives a higher current carrying capacity than an ACSR of the same equal size, and reduces the
sagging effect considering the transmission tower height.
Applications of the ACSS cable
An ACSS cable is designed for use as an overhead power transmitting cable line alongside the high temperature line, when a connection is done over the existing line connection. The benefits of ACSS make it preferable in applications requiring an increased current carrying capacity, with prevailing tensions alongside the clearances.
