ACAR (Aluminum Conductor Alloy Reinforced) Wire

Learn about the ACAR (Aluminum Conductor Alloy Reinforced) wire we have available for your projects.

ACAR Applications

Aluminum conductor alloy reinforced (ACAR) wire is used extensively for bare overhead transmission, whether it's for a primary or secondary distribution cable. Due to a higher strength-to-weight ratio, ACAR is preferred for a line design where strength and ampacity are central.

ACAR Specifications

ACAR is manufactured according to the following ASTM specifications:

  • B230: Aluminum alloy 1350-H19 for electrical uses
  • B398: 6201-T81 aluminum alloy for electrical uses
  • B524: Concentric-lay-stranded aluminum wire made from extra-hard aluminum alloy 1350-H19 and round aluminum alloy, which is reinforced for overhead electrical applications


This concentric-lay-stranded conductor consists of aluminum-alloy 6201-T81 wire and aluminum 1350-H19. Depending on the strength and current requirements, you can choose single or multi-layer ACAR conductors.

For equal weight, the aluminum conductor alloy reinforced offers more ampacity and strength than ACSR conductors. Ordinarily, 1350-H19 wire surrounds a 6201-T81 core. However, some designs have the 6201-T81 and 1350-H19 wire stranded in one layer.

ACAR Features

The 6201-T81 offers a higher strength-to-weight ratio, making ACAR conductors ideal for distribution and transmission applications where:

  • Conductors should have a higher strength than AAC
  • Conductors should have a lower weight than ACSR
  • Conductors should have higher current capabilities than AAAC and ACSR
  • Corrosion resistance should exceed ACSR conductors

Contact Peak Substation Services for ACAR Wire Needs

Quality, reliability, and peace of mind are among the largest considerations for any industrial customer or utility contractor. Fortunately, you have a proven resource with Peak Substation Services. Consider us your one-stop shop for electrical and structural materials packaging.

Peak Substation Services first opened in 2006. Since then, we have served hundreds of clients, helping them achieve successful substation projects. We have handled over 1,000 packages, and our staff team has more than 100 years of combined experience in substation packaging, distribution,design, construction, manufacturing, and procurement.

Count on us for comprehensive material take-offs from specifications and drawings. We also serve our customers with budget information, guide their purchases, and ship throughout the United States. Furthermore, our team is highly experienced in shipping high-voltage materials and parts as needed through our Product Sales department.

You gain value in many ways by partnering with us. The greatest benefit is that we trim the work hours required to coordinate and complete a project. We’ll also minimize your project's combined material costs by leveraging our vendor relationships and maximizing your purchasing experience.

Contact the Substation Packaging Experts

Peak Substation Services is a go-to resource for industry needs. With 1000+ fulfilled packages for clients, we offer electrical and structural materials packaging to industrial partners, utility contractors, and for utilities across the U.S. Our combined employee experience spans more than a century, making us a trusted provider for substation packaging, distribution, manufacturing, procurement, and construction. 

Get in touch with us for all of your electrical and structural packaging needs. As your packager of choice, we help you design, source, and receive your project supplies by facilitating purchase and delivery logistics. We also offer substation and transmission solutions that support material take-offs, including drawings and specifications, budgeting, and shipping.

Our packaging services save you valuable man-hours to reduce combined material costs and enhance vendor relationships and the purchasing experience. Because substations and overhead transmission lines follow strict construction schedules, a packager issues bill-of-materials to minimize the utility's and consultant's direct participation. Our team is responsible for pricing the entire order, including grounding equipment, bolts, and nuts.

Additionally, we provide premier product and component sales. We supply new and replacement parts, whether you're in the market for control cables, electrical switchgear, or other substation accessories. We've built strong industry networks throughout our 15+ years in the business, allowing us to leverage effectively when sourcing quality substation components.

Our expertise doesn't end there: You can also count on Peak Substation Services to deliver utility poles to finish your project. Wherever you are in the U.S., we'll ship your poles right when you need them.

Find what’s needed for your project at Peak Substation Services. We're always ready to serve you at our corporate office, located at 801 First Avenue North, Birmingham, Alabama. Send us a message, email us at, or call us at (877) 324-0909 to order reliable ACAR conductors or to receive a quote.
