Heavy-Duty 3B&S Automotive Cable for Reliable High-Current Power Distribution

When dependable power transfer is critical, the 100m Roll of KEY 3B&S (26mm²) Black Single Core Automotive Cable delivers the performance professional installers demand. Manufactured using Oxygen Free High Conductivity (OFHC) copper, this premium automotive cable provides exceptional conductivity, reduced voltage drop, and long-term durability in demanding automotive, marine, industrial, and off-grid environments. Designed to support high-current applications across 12V, 24V, and 48V electrical systems, it offers the ideal balance of flexibility, strength, and electrical efficiency.

About KEY Tubing & Electrical

KEY Tubing & Electrical (KTE) is an Australian-owned manufacturer with over 60 years of industry experience supplying electrical, cable, tubing, and custom-engineered solutions to industries across Australia and around the world. Based in South Australia, KEY is known for its commitment to quality manufacturing, rigorous quality standards, and reliable products designed for demanding automotive, electrical, industrial, and resource sector applications. KEY continues to support Australian industry with a strong focus on performance, durability, and dependable engineering.

Superior Conductivity with OFHC Copper Construction

Unlike conventional automotive cables, this 26mm² single core automotive cable utilises high-purity OFHC copper to maximise current flow and minimise resistance. The reduced impurity content helps lower heat generation under load, improving overall system efficiency and reducing energy losses. Whether powering a dual battery setup, feeding a DC-DC charger, or supplying current to a high-capacity inverter, this cable helps maintain stable voltage delivery throughout the system.

OFHC copper also offers enhanced resistance to hydrogen embrittlement and mechanical fatigue. This makes it particularly suitable for installations exposed to constant vibration, temperature fluctuations, and harsh environmental conditions commonly encountered in 4WDs, caravans, commercial vehicles, marine vessels, and industrial equipment.

Designed for High-Current 12V, 24V & 48V Systems

The substantial 26mm² conductor size, commonly referred to as 3B&S automotive cable, is ideal for applications requiring dependable high-current performance over longer cable runs. Rated for a maximum DC voltage of 120V, it is perfectly suited for modern vehicle electrical systems, lithium battery installations, inverter circuits, auxiliary battery banks, and renewable energy systems. The cable's low-resistance construction helps minimise voltage drop, making it an excellent choice for demanding power distribution applications.

Common Applications Include:

  • Dual battery systems in 4WDs, caravans and camper trailers
  • Battery interconnects and auxiliary battery wiring
  • DC-DC charger installations and lithium battery systems
  • High-current inverter and solar power systems
  • Marine electrical systems and battery banks
  • Commercial vehicle, fleet and industrial power distribution

Built to Australian Standards for Long-Term Reliability

Manufactured to comply with AS/NZS 1125 conductor requirements and AS/NZS 3808:2000 insulation standards, this cable delivers dependable performance in demanding environments. The durable V90 insulation provides excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation through chassis rails, conduits, and tight engine bay spaces.

The black outer sheath allows clear identification for negative earth and grounding circuits while maintaining a professional appearance in automotive, marine, and industrial installations. Supplied in a convenient 100-metre roll, it is an economical solution for workshops, auto electricians, fleet maintenance operators, and large-scale wiring projects.

Works great in my setup
I got this for my work desk, and it does exactly what it's advertised to do: it holds my laptop (which is 16 inches). And it doesn't wobble and shake whenever I type on my external keyboard (I use a Unicomp Ultra Classic, which uses buckling springs, so I'm putting a decent amount of force into each keypress - if a stand is not stable, it will be immediately obvious to me), and I can even move my mouse underneath the stand without running into any problems. (Before, when my laptop was sitting directly on the desk, it was annoying how it made me move my keyboard around and inhibited my range of mouse movement, but now I can place my keyboard right where I want it and use my mouse as I please.) The stand feels very sturdy and well-constructed, and it keeps my laptop at eye level. Height-adjust would be nice, but I have yet to find a good quality adjustable laptop stand, so I'll just use books to adjust it if the need arises. The box it comes in is also quite nice. This thing freed up desk space where I needed it and is unlikely to ever fail (there are no moving parts), so I wholeheartedly recommend it to anyone looking for a laptop stand.

Beautiful design
Simple, functional and beautifully designed, I'm glad I bought it. (not a five starts just because I thought it was higher, but again, my fault for not reviewing the specs first)

Not Your Average Laptop Stand
One of the things that I always worry about with stands for my computer is how sturdy they will be. If they aren't sturdy, they aren't really worth having. This is super sturdy -- I don't feel any bounce or flex when I work on it. It's also super well made and looks good sitting on my desk. Both of those things make this one of the best stands that I've used. I just wish it were adjustable.
