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.

This is one “under the radar” gem!!
Size: Large, Color: Coral
This is one “under the radar” gem!! Very strong internal squeaker and way tougher than it looks. My big 125lb Shepard-Husky mix gave it heck, then made it his new buddy. He’ll occasionally give it the business but on the whole, it’s surprisingly tough and my big boy loves it. Nice price!!

Cute but small

Cute stuffy and has not yet ripped. While my dogs plays with it, the toy is a bit small for him. For reference he is 120lbs.

My Puppy Loves this Indestructible Dragon
Size: Large, Color: Pink, Size: Large, Color: Pink
My puppy (8 month old black lab mix) loves, loves, loves her dragon. She has had it for 2 months now. It is one of her favorites and gets daily rough play time. It's her go-to toy for fetch and tug games, as well as just general mouthy play. The squeaker gave out after about 4 weeks, but she would binge squeak for prolonged periods (kind of like chomping on gum) so it was almost a blessing when it went silent. She still chomps on it, but at least now I don't have to hear it. Other than the fact that it's a little grungy and bedraggled from so much loving, it is still in amazing shape. The seams and fur are all still intact. There are no visible holes, rips, or weak spots. I love Chew Guard Technology. This dragon replaced her goDog Iguana (from PetSmart) that developed a tear in the fur after about 4 months of heavy use. (It was superficial, just the outer fur layer and not the innards, but we disposed of it before she could eat more fur.) She can be pretty rough on her toys and I can never predict if any given toy will last minutes or months. The goDog stuffies definitely fall into the "months" category, even with rough daily use. Edit: The dragon lasted about 6 months of intensive, hard play before it developed a small tear in the fur. I patched it a couple times, but once my pup discovers a weak spot, it's the kiss of death for any stuffed item. We had to dispose of the dragon (so sad) to keep her from eating any more of the fur. We replaced the dragon with the goDog Chameleon, which is still going strong. I think we will go back to the dragon for our next toy because it's just so darned cute. We gave the dragon to my niece for her golden retriever puppy who is very chew-happy. That dragon is also doing well. You've just gotta love that chew-guard technology. This is one tough toy.

Indestructible Toys My Dobermans ❤️
Size: Large, Color: Mesh Green
Actually Respect! goDog Is a Lifesaver The variety of size and colors are phenomenal 😇 I have two Dobermans — serious, determined power chewers — and I’ve spent years trying to find toys that survive even a few days. I’ve tried the big brands (Kong, Goughnuts, Jolly Ball, you name it) — and while some toys last a little while, almost everything eventually ends up shredded, de-squeaked, or in pieces. goDog toys are the ONLY plush toys my Dobermans won’t destroy. We own multiple goDog toys now — dragons, dinosaurs, lizards — mostly in the large size (perfect for Dobermans), but even a few medium-sized ones hold up surprisingly well. Here’s what’s amazing: • They love them — actually carry them around, toss them, chew them gently, and squeak them happily. • They do not rip them apart — no matter how much tugging, chewing, or wrestling happens. • Large sizes are best for Dobermans (and other big breeds) — but even mediums survive for calmer play sessions. • No ripped seams, no stuffing everywhere, and no destroyed squeakers after months of use. What makes goDog toys different? The secret is their Chew Guard Technology — • A reinforced, high-strength inner mesh layer under the soft plush • Double-stitched seams • Durable yet flexible material that somehow resists punctures, tears, and brutal shaking The outside stays soft and fun, but the inside is built like armor. It’s NOT a super hard rubber or rough canvas — it still feels like a cuddle toy, but it’s engineered to survive serious chewing. Materials include: • Durable polyester plush • Chew Guard inner lining (high-tensile mesh fabric) • Reinforced stitching • Non-toxic squeakers • Safe for dogs to play with long-term Real Owner Advice: • Always size up if you have a heavy chewer — large sizes are a must for Dobermans or similarly strong breeds. • Medium sizes are fine if you supervise or your dog is more moderate with toys, but the large toys are built tougher overall. Final Thoughts: If you have big dogs, strong jaws, or just tired of wasting money on destroyed toys — goDog toys are a must. No other plush-style toy even comes close. My Dobermans will destroy almost anything… but they treat their goDog toys like treasured companions. No holes, no rips, just happy dogs. Follow me here on Amazon for more honest, dog-tested reviews! Like this review if it helped — I’ll be uploading even more proven tough toys and pet essentials soon!
