KEY 100m 4mm (1.84mm²) Twin Core Automotive Cable: Premium 22A Twin Core Wiring for Demanding DC Applications

The 100m Roll of KEY 4mm (1.84mm²) Twin Core Automotive Cable acts as the backbone of reliable low-voltage electrical systems. Engineered with 1.84mm² Oxygen Free High Conductivity (OFHC) copper conductors, this 100m roll delivers consistent power transmission for automotive, marine, and off-grid setups. Unlike standard general-purpose wires, this cable is built to resist vibration, temperature extremes, and environmental stress, ensuring your electrical accessories operate at peak 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.

Superior Conductivity with OFHC Copper

At the core of this cable is 99.9% oxygen-free copper. This high-purity material offers superior electrical conductivity compared to recycled or standard tough pitch copper, resulting in lower voltage drop over long cable runs—critical for maintaining the efficiency of fridges, pumps, and DC-DC chargers. Furthermore, OFHC copper resists embrittlement over time, maintaining flexibility and structural integrity even in high-vibration automotive environments.

Engineered for Heat and UV Resistance

Australia’s harsh climate demands insulation that can survive the elements. This cable features V90HT (High Temperature) PVC insulation, rated to 90°C, preventing the jacket from softening or melting in hot engine bays or enclosed canopies. The UV-stabilised black outer sheath provides a durable barrier against sun damage, oil, and grease, making it an excellent choice for external trailer wiring, solar interconnects, and exposed chassis runs.

Safe for 12V, 24V, and 48V Systems

While perfectly suited as 12V automotive cable, the high insulation breakdown voltage allows for safe operation up to 120V DC. This makes the cable highly versatile for 24V commercial vehicle wiring and 48V lithium battery systems found in modern caravans and off-grid homes. By handling higher voltages safely, it ensures future-proof installations for evolving energy needs.

Streamlined Installation

Professional installers and DIY enthusiasts alike value the easy-strip outer sheath and clearly colour-coded Red and Black cores, which minimize polarity errors and speed up termination. The twin-core construction provides a neat, single-cable run, eliminating the mess of taping separate wires together and offering additional mechanical protection against chaffing.

Key Features

  • High-Purity OFHC Copper: 1.84mm² conductors ensure maximum conductivity and reduced resistance.
  • High Current Capacity: Rated for 22A (subject to de-rating) to support heavy-duty accessories.
  • V90HT Insulation: Withstands continuous operating temperatures up to 90°C.
  • UV-Stabilised Sheath: Resists cracking and fading in direct sunlight.
  • Wide Voltage Range: Suitable for 12V, 24V, and 48V DC applications (Max 120V).
  • Compliance: Meets AS/NZS 1125 and AS 3808 standards; RoHS compliant.

*Typical de-rating factors apply based on ambient temperature, bundling, and run length; ensure cable sizing accounts for voltage drop in your specific installation.

Secure Your Electrical Connections

Don't compromise on your wiring infrastructure. Equip your workshop or project with the KEY 4mm (1.84mm²) Twin Core Automotive Cable for a professional, long-lasting finish. Whether outfitting a 4WD for touring or wiring a marine console, this cable delivers the durability and performance required for critical DC circuits.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.
