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.

They honor their product.
I've been dealing with Asurion for over a decade now. They're my first choice when making a purchase that I know I'm going to have around for a while. Asurion backs its product to the hilt. I purchased a mid-range priced printer about 2 1/2 yrs. ago along with a 3yr. warranty from Asurion to cover any unexpected 'surprises' that might happen to pop up. Fast forward to approximately 3 months ago, when my printer decided that it wanted to start acting up. The print quality was taking a nose dive; colors were beginning to drop out, showing streaks and fading. Clarity and sharpness are virtually gone. I contacted Asurion about the problem. I couldn't have found a nicer rep to deal with. She said not to worry and within minutes had the situation under control. She sent me all the information and pre-paid postage on how to pack and have my unit shipped to their repair facilities. In less than a week my unit was repaired and returned to me. However, this is not the end of the story. Within a few days, my unit was acting up again and doing the same thing it went in for. Again, I got hold of Asurion (Same great service, different girl). We repeated the same process as before, but this time the unit was there about a week longer. When I finally received the unit, I immediately hooked it up and put it through the numbers, testing everything. To be blunt, the print quality was worse than the 1st time it went in for service. After voicing my displeasure (basically having a hissy-fit), I regained my composure and contacted Asurion, again! This time they told me that since their techs were unable to resolve the issue and to not have me waiting any longer than I have already, they're going ahead and refunding the total amount I paid for the unit. Even though it was somewhat of a Pain-in-the-ASS to go through, I couldn't be happier. Within 48 hrs. I had my refund in hand and I turned around and purchased a replacement Printer. Moral to the story, have a contingency plan, Just in case. Check out Asurion: Great customer service - Nice people, very competitive pricing for their products and they honor their word by their actions. Highly recommend Asurion to anyone.

Great job by Asurion!
Asurion handled my claim quickly and efficiently. My return was picked up by UPS and an Amazon gift card for the full amount was received as promised. Very happy with the process.

Make sure you read the terms and conditions and don't let them off the hook
Asurion is counting on the fact that you don't know how to read. They made the claim process aggravating and as difficult as possible. I CAN read and had to review the terms and conditions with them on the phone and threaten to involve an attorney before they would honor the coverage. They tried to say my product was not portable, when the word "portable" is literally in the name of the product. Then they tried to say the the accidental drop was not covered, but it clearly states in the terms and conditions that an accidental drop and a cracked screen is a covered event. I buy the coverage almost every time I am offered it, but I will be rethinking that going forward and Amazon should consider finding a different company to issue the protection plans for their products because I fear this is the beginning of a lot of complaints. I have filed a claim in the past and it was very straightforward and easy, but they must have a new company managing the plans now, because it was anything but easy. If I was an older person who was not tech savy, or who just took someone's word at face value, I would be out the cost of my item and the protection plan. BUYER BEWARE
