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.

Perfect for High-Drive Dogs & Surprisingly Durable (six month review)
I use this ring ball for structured fetch and tug sessions with my high-drive German Shepherd mix (91 lbs. at 10 mon.), and it’s easily the best toy we’ve added to our routine. What makes it truly exceptional is how it allows my dog to engage in the full canine predatory sequence: • Chase: He locks in visually and bolts after the ring when I throw it. • Grab & Hold: He brings it back, pins it against my leg, and bites down firmly (the toy—not the leg!)—his way of acting out the natural catch-and-control behavior. • Unalive & Tug: We finish with a strong tug session, which satisfies his instinct to grip and shake—basically his version of “making the toy unalive.” • Settle & Chew: Afterward, he relaxes with a chew toy or eats—completing the full physical and mental cycle in a healthy, balanced way. Durability is outstanding—this toy stands up to intense tug sessions with no tearing or damage, even with a 91 lb powerhouse. My senior dog also joins in for double tug play, and it holds up beautifully to that too. I don’t leave this toy down for chewing—it’s not a chew toy. I use it specifically for fetch and tug, then put it away when we’re done. This keeps it exciting and extends its lifespan. My dog has other chew toys he can use freely throughout the day. This isn’t just another fetch toy—when thoughtful it provides a structured, instinct-satisfying experience that’s mentally enriching and physically engaging. If you have a high-drive or working breed, or a dog who thrives on interactive play, this ring ball is 100% worth it.

This baby "takes a licking and keeps on ticking"!
Pattern Name: Platypus
I have three Labs who LOVE playing tug of war with each other and their human family. I bought this stretchy plushie on a whim and it has become one of their favorites! Our pups pull HARD and this thing can TAKE IT without ripping or losing it's elasticity. It does have some holes and has lost an ear, but it is still functional - just a bit raggedy. ANY plushie that lasts more than a couple days with these ladies is a winner...and this one has been played with daily for several WEEKS at this point! If you have strong pullers who also like the soft, squeaky feel of a plushie, this toy is a sure bet.

It survived longer than others
Pattern Name: Pull Monkey, Pattern Name: Pull Monkey
My Maltese mix has destroyed every single one of his squeaker toys within a week. This is the only stuffed toy I've found so far that lasted almost 2 months before he successfully gutted and 3 months before it officially needed to be replaced. I mean, just look at the image and see the rough play it's been through. I do wish the squeaker was larger to help it survive just a bit longer but I am pretty happy with this toy and so is my dog. The rope arms and legs are great features as they slide through the body and really helps encourage tug play. The price is fair for the size and quality of the construction and is overall a pretty good purchase. I plan to buy a few more to keep as backup.
