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.

Inexpensive and Effective
Size: 3 Fl Oz (Pack of 1), Size: 3 Fl Oz (Pack of 1)
I’ve struggled with dry sensitive skin and eczema my entire life and this is now my ride or die facial moisturizer. It’s so much less expensive than luxury brands that I have tried and works better. It absorbs so well, leaves no residue, and a small amount goes a long way. I will say, if you have an active eczema flare it can sting a tiiiiny bit but that’s an eczema thing. It causes zero irritation or inflammation there’s just some sensation as it goes on. Vanicream as a brand in general is soooo eczema friendly. Life changing.

This stuff works nicely
Size: 3 Fl Oz (Pack of 1)
So I don't typically leave reviews, but I feel like this lotion has been fantastic to me. I typically don't use lotion because I hate the feel, but my face really needed it. I have dry/oily skin. My skin gets gross and flaky, yet it's pretty oily. I've always dealt with it. I decided to go ahead and buy this stuff because I couldn't take my dry skin. It helps soooo much and you barely need any. I use a dime sized amount and really focus on my problem areas. It lasts all day, not too thick and not too watery. Not greasy at all for me and soaks in very nicely. Again, it lasts all day and I don't need touch ups, even on bad skin days. I don't ever break out and it's never clogged my pores, but to be fair I've never really had skin that's broken out much before. The one thing I did notice, before using this stuff I started noticing more fine lines around my eyes/forehead. I've been using this stuff for about a year and you can barely see them anymore. I have haven't changed my diet, it's pretty atrocious honestly, so I really feel this lotion has worked wonders on its own. Also I still have a decent amount left in the bottle and I bought it almost a year ago. I'm going to try their body lotion next. Hope this helps, or at least give it a whirl!

My rosacea approves
Size: 3 Fl Oz (Pack of 1)
I have Rosacea, dry, sensitive, reactive skin and perimenopausal skin. My rosacea products tends to dry my already dry skin and this has been been a great moisturizer. My skin looks dewy, dullness and dryness have improved in just 2 days; I haven't reacted with sting and redness like I usually do and when I wake up I still have a dewy not greasy face even though I sleep on my sides and toss and turn all night. Definitely going to buy again since the bottle size is good, a lil goes a long way and does not make my face react like the CeraVe.

Your makeup won't get ruined! ❤️
Size: 0.47 Ounce (Pack of 1)
I'm new to skincare and I didn't know we were supposed to wear sunscreen! 😱 Turns out it's arguably the most important step of skincare. First, I like the texture of this sunscreen. It's not greasy, it's velvety and smooth. It feels nice on my skin. I used this for the first time yesterday, and I just want those of you to know who are considering buying this, it applies well against makeup! That was one of my main concerns. I did my skincare with this sunscreen as a final step, then put on my makeup. The sunscreen acted as a primer, honestly, so I skipped primer. When I reapplied the sunscreen hours later, my makeup didn't smear! Instead I had a nice, healthy glow to my skin. I actually think it enhanced my makeup; my makeup seemed to last longer than usual. If you find yourself to be TOO glowy after a while, just apply a bit of translucent powder and your makeup will stretch even longer. Bonus: It fits nicely in your purse! Good for people like me with a million things they insist on carrying around.

Daily Staple Sunscreen
Size: 3 Fl Oz (Pack of 1)
I’ve been really impressed with this sunscreen—it’s become a daily staple for my face and hands. The SPF 70 gives great peace of mind, especially with regular sun exposure, and it feels lightweight rather than heavy or greasy. It absorbs quickly and doesn’t leave that thick white cast, which is a huge plus for everyday wear. On my face, it layers well under makeup without pilling, and on my hands, it doesn’t feel sticky or transfer onto everything I touch. I also appreciate that it holds up well throughout the day without needing constant reapplication (unless I’m outside a lot). Overall, it’s a reliable, high-protection sunscreen that’s comfortable enough to use every day.
