ACSS/AW (Aluminum Conductor Steel Supported)

Aluminum Conductor Steel Supported (ACSS/AW) wire provides corrosion resistance and improved ampacity. Learn how this wire from Peak Substation Services is ideal for your overhead transmission and distribution lines.

ACSS/AW Applications

ACSS/AW is mainly used in overhead transmission and distribution lines. Its meticulous design allows it to work continuously in environments of up to 250°C—all while retaining its strength.

ACSS/AW wire is robust, providing reduced conductor sag even with emergency electrical loadings. Pre-stretching the conductor during installation activates its self-damping capabilities. Additionally, the long-term aluminum creep doesn't affect its final sags.

Aluminum Conductor Steel Supported wire is ideal for reconductoring applications that require more current with existing clearances and tensions. It also serves new line operations that allow for structure economization because of lower conductor sag. Additionally, you can use this conductor for lines that experience aeolian vibration and in new line applications for high emergency loadings.

ACSS/AW Specifications

ACSS/AW conductors from Peak Substation Services meet or exceed the following ASTM specifications:

It’s also worth noting ACSS/AW strandings match B232 ASTM specification.

Construction

The ACSS/AW conductor consists of concentric-lay-stranded components. Its central core is made of steel strands, surrounded by one or more layers of aluminum 1350-0 wire. In addition, it features the "0" (soft or fully annealed) temper aluminum, which means the steel core primarily bears the conductor's mechanical load. The steel core wire is coated with aluminum to prevent corrosion.

ACSS/AW offers strength characteristics similar to ACSS; however, it features aluminum-clad steel core wire. As such, it delivers slightly higher ampacity and corrosion resistance. 

ACSS/AW Conductor Types

The ACSS/ AW spec sheet consists of these conductor variations:

Squab, Parakeet, Bittern, Rook, Canary, Starling, Gannet, Scoter, Junco, Lark, Brant, Eagle, Linnet, Drake, Mallard, Tern, Hen, Parrot, Lapwing, Falcon, Condor, Rail, Chukar, Mockingbird, Macaw, Roadrunner, Towhee, Cuckoo, Cardinal, Peacock, Bluebird, Ostrich, Kiwi, Ibis, Curlew, Dove, Bluejay, Finch, Flicker, Grackle, Redwing, Thrasher, Hawk, Joree Snowbird, Stilt, Canvasback, Grosbeak, Oriole, Flamingo, Nuthatch, Ruddy, Dipper, Egret, Martin, Teal, Bobolink, Pheasant, Wood Duck, Bunting, Plover.

It can be difficult to get the right cable for your project with all these different variations. However, you might have an easier time with the following checklist for reference:
