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.

Fabulous product! Made my skin feel soft!
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
This product goes on smooth and a little goes a long way. I used it today for the first time and was very pleased that it held up to my sweating in the heat doing farm work! It doesn’t bother my very sensitive skin, in fact it is quite soothing. A little goes a long way. With about a quarter size amount I was able to do both arms and my face. I was outside for several hours and didn’t burn like I usually do. It is basically unscented which is nice and isn’t sticky.

Works well and neutral scent. Has white cast.
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
Not a bad sunscreen. I wore it yesterday at a water park, reapplied every 1-2 hours, and didn’t get burned. Works well as a sunscreen and has a very neutral scent, which I appreciate a lot. However, like most mineral sunscreens it feels a bit heavy and definitely has a white cast. I’m pretty pale and still had a hard time getting it to blend in. It’s priced well, available at many super markets, offers good protection, and the neutral scent means I will continue using it (I stopped using some other sunblocks because of the scent alone). Just know it feels heavy and has a white cast.

Favorite Mineral Sunscreen
Size: 5 Fl Oz (Pack of 1), Set name: Tube - 5 oz.
This is my go to mineral sunscreen. It's very effective at protecting your skin from the harsh UV rays. It great to use for any water based activities, since it stays on your skin regardless of how wet it gets. I'm also able to use it under my eyes without it irritating them. Though it does leave behind a white cast after applying, but I personally don't mind it.

My favorite mineral sunscreen for Hawaii
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
My favorite mineral sunscreen for Hawaii. I just got back from a week in Maui. I took 3 different brands of mineral sunscreen. For Maui it has to say mineral to be allowed. Of the 3 the Blue Lizard was our favorite. It went on white but rubbed in the quickest. We applied in our room before going out for several hours and never got a burn the entire week. I only reapplied once on a hike. Would recommend Blue Lizard!

Great for very sensitive skin!
Size: 3 Fl Oz (Pack of 1), Set name: Tube - 3 oz.
Use this every day. It's my primer. Lol I have extremely sensitive skin to the point where one wrong move lands me in the ER. This worked for me. Slight greasiness but works well for me as I can't wear foundation. This at least hydrates and protects. Love it.
