Automotive Wire

Aluminum core with orange insulating sheath for automotive cable conductors

Automotive wires are the most inconspicuous yet important automotive parts. All the commands that owners give to their cars are delivered through these cables. Modern automobiles are filled with a variety of electronic devices that form a huge, distributed system. Every signal generated by the computer while driving has to be transmitted through the cable harness, and the importance of the wiring harness system is just like the human nervous system.

Description of the Automotive Cable

ZMS cable offers customers a wide range of automotive wires and cables to choose from, and we can also select the right automotive wire connector for the cable program. They can be used for a wide range of automotive applications and systems, such as automotive fuse blocks. Automotive mains wire is a type of wire used for automotive applications. KVCABLE also sells the highest quality automotive wire loom – PVC automotive wire, which is typically used in under-the-hood or cabin applications.

Layout of automotive wires within the automotive structure

What are the different types of automotive wires? Cross-link automotive primary wire comprises three kinds of wire: Type GXL Wire. GXL wire features a thin wall or thickness and is used mainly for trucks and trailers. There are also types of SXL wire and type TXL wire.

As shown, the best wire for automotive is SXL wire. SXL is your standard cross-linked auto electrical cable that is mostly used in industrial general circuit wiring. Since it is the golden standard of industrial auto wiring, it is also often called “primary automotive wire.” SXL cables produced by ZMS possess excellent abrasion resistance.

Different Types of Automotive Wire Technical Size



SWG DIAMETER (Millimeters)


AWG DIAMETER (Millimeters)


10 Gauge Wire

0.1280 in

3.251 mm

0.1019 in

2.588 mm

Very thick wire. Often used by silver smiths using forging or welding techniques. Good for chokers, stiff bracelets, rings.

12 Gauge Wire

0.1040 in

2.642 mm

0.0808 in

2.052 mm

Still very thick wire, still hard to bend intricately by hand. Good for chokers, stiff bracelets, even wire-sculpted rings.

14 Gauge Wire

0.0800 in

2.032 mm

0.0640 in

1.626 mm

Heavier Wire. Good for chokers, stiff bracelets, even wire-sculpted rings.

16 Gauge Wire

0.0640 in

1.626 mm

0.0508 in

1.290 mm

Heavy Wire. Commonly used for chokers, heavy-duty clasps

18 Gauge Wire

0.0480 in

1.219 mm

0.0403 in

1.024 mm

Med-Heavy Wire. Good for making clasps, chokers, wire sculptures.

20 Gauge Wire

0.0360 in

0.9144 mm

0.0319 in

0.8128 mm

Medium wire. Size most often recommended for creating wire-jewelry using wire jigs and other wire sculpturing techniques. Good for making heavy-duty earwires and lightweight clasps because it’s still pretty easy to work with but strong as well. Dead soft is best, as thicker wire starts getting harder to bend. About 19 feet of 20 gauge wire to the ounce.

22 Gauge Wire

0.0280 in

.7112 mm

0.0253 in

0.6426 mm

Medium-Fine Wire. Very versatile size because it is pretty thick but most beads (like crystals and stone beads) can fit on it. Dead soft is a good way to go with this wire. Good for making earwires, headpins, and rosary style wrapped links. One ounce of 22 gauge has about 31 feet of wire.

24 Gauge Wire

0.0220 in

0.5588 mm

0.0201 in

0.5105 mm

Fine wire. Good for beads that have small holes in them such as pearls. Half-hard is good in this size as it adds a little bit of body and strength to a slender wire. Good for making rosary-style beaded links. In an ounce of 24 gauge there is about 48 feet of wire.

26 Gauge Wire

0.0180 in

0.4572 mm

0.0159 in

0.4039 mm

Very fine wire. Good for beads that have small holes in them such as pearls. Half-hard is good in this size as it adds a little bit of body and strength to a very slender wire. Good for making rosary-style beaded links. In an ounce of 26 gauge wire there is about 76 feet of wire.

28 Gauge Wire

0.0148 in

0.3759 mm

0.0126 in

0.3200 mm

Extremely fine wire, not much wider than a human hair. Mostly used for wire crocheting and wire knitting. Hard to handle, tendency to get tangled.

The above wiring harnesses can be divided into battery wires and high-voltage wires respectively. New energy vehicles generally use a voltage resistance level DC greater than 60V less than 600V. Coaxial cable, low voltage conductor, voltage resistance level DC <60V or AC <25V, etc. At the same time, the low-voltage wire mentioned here is one of the most used wires in the car. The role is to provide low-voltage power for all electrical appliances in the car, as well as the role of signal transmission.
