Heavy-Duty Twin Core Automotive Cable for Reliable Power and Earth Connections

The 100m Roll of KEY 4B&S (20.29mm²) Twin Core Automotive Cable is designed for high-performance DC power applications where reliability, efficiency, and durability are essential. Featuring two insulated conductors within a single outer sheath, this premium twin core cable simplifies installation while providing a neat, professional wiring solution for automotive, marine, caravan, off-grid, and industrial electrical systems. Manufactured using Oxygen Free High Conductivity (OFHC) copper, it delivers superior current flow, reduced voltage drop, and dependable long-term performance.

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.

Premium OFHC Copper for Maximum Conductivity

At the heart of this 4B&S twin core automotive cable is high-purity OFHC copper, which provides lower electrical resistance compared to standard copper conductors. This results in improved efficiency, reduced heat generation, and better voltage retention across longer cable runs. Whether powering battery systems, inverters, chargers, or auxiliary equipment, the cable helps ensure stable and consistent power delivery.

The flexible multi-strand conductor design also improves durability in environments subject to vibration, movement, and temperature fluctuations. This makes it ideal for installations in vehicles, boats, caravans, heavy machinery, and renewable energy systems where long-term reliability is critical.

Ideal for 12V, 24V and 48V Electrical Systems

With a conductor size of 20.29mm² per core (4B&S), this cable is commonly used for medium to high-current applications requiring both positive and negative conductors within a single cable assembly. The twin core design reduces installation time while providing additional protection against abrasion and environmental exposure. It is suitable for modern 12V automotive systems, 24V commercial vehicle installations, and 48V lithium battery applications.

Common Applications Include:

  • Dual battery systems in 4WDs and touring vehicles
  • Caravan and camper trailer battery installations
  • Marine battery banks and onboard electrical systems
  • DC-DC charger and battery charger wiring
  • Solar battery storage and off-grid power systems
  • Inverter installations and auxiliary power distribution

Built for Harsh Australian Conditions

Manufactured to comply with AS/NZS 1125 conductor standards and AS/NZS 3808:2000 insulation requirements, this cable is designed to handle the challenges of demanding automotive and industrial environments. The V90 insulation offers excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation.

The twin core construction keeps positive and negative conductors neatly contained within a durable outer sheath, helping to reduce cable clutter and improve protection. This makes it particularly popular for long cable runs between batteries, chargers, solar systems, and auxiliary equipment.

Better than other flimsy trays
Color: Black, Size: Rectangle, Color: Black, Size: Rectangle
I got this to replace another flimsy valet tray I got as a gift. This one is way more sturdier, looks nicer, bigger, and has a nice feel.

Looks great, doesn't hold much so measure carefully
Color: Gray, Size: Rectangle
I got this organizer for my husband to keep his stuff by the door. While it's a little smaller than I'd hoped, it looks great in the entryway. It's super easy to snap together, but feels like the material could be damaged easily if you're not careful. He is able to store his keys, wallet, and sunglasses in it, and throws hit hat on top. Overall we are really happy with it.

Perfect
Color: Blue, Size: Square
Just what I needed. The size is perfect as I didn’t want anything too large to place my watches and other accessories inside near the corner of my desk. Its size is essentially 7x7, and the design is sleek compared to other organizer holders. I got the color in blue and it looks stunning with the rest of my setup. I’m unsure about other reviewers, but mine came safely and the leather walls are decently thick, so it’s not too flimsy when buttoned together which holds very securely. There are hole spaces at the bottom corners once assembled, so if you have super small items such as beads or really small jewelry, they could potentially fall out, but most of my items are large enough that won’t be of concern. If you have a wire charger near by, the holes could be used to charge your smartphone inside, which has its own practical usage. Overall, I’d definitely recommend it if you’re on a lookout for a sleek but compact organizer holder, and I personally will consider getting another one in the future for myself for other household belongings.

So immersive, easy to set up and affordable it beats our Phillips Hue set up!
If you want a stunning, immersive viewing experience this set it for you! It can sync with up to 5 Govee light strips or bulbs for and even more immersive experience too! We have 3 different Govee backlight set Ups and this is the best one. It levels up our gaming experience. I cannot imagine watching movies without one now. Theater experiences are lack luster in comparison. Definately watching their how to videos on proper set up and syncing using those funny orange foam pieces! It makes things so much easier! The difference in the color displays are amazing! We synced 3 Govee rbgic light strips and two govee bulbs to the system. We get so many compliments on how incredible the room looks. When combined with relaxation, music or oled videos it's like a sanctuary! It is better in some ways than the Phillips $500 Hue set up we have on another set. It's a good idea to leave some of the adhesive spots on the led strip unused and covered in case your TV dies or you get a new one. This adhesive strip is strong and not reusable. Our new TV died during a power outage. This strip came off fine but lost all it stickiness once removed. Hopefully you won't ever have to remove yours. This is definately a 100 out of ten for us!
