Multiconductor cables are comprised of two or more conductors contained within a single jacket. They can be constructed in various ways depending on different needs and environmental factors. Shielded and unshielded options are available. Thankfully, we stock a vast and diverse range of multicore cables to suit your application.

That includes products from trusted manufacturers in the industry, such as Lapp Group, Carol Brand / General Cable, and Olympic Wire and Cable Corp. You'll also find quality, cost-efficient multiconductor cables from our RS PRO line.

Browse our products below and filter your options by manufacturer, number of conductors, wire size, shielding, and more. Most product listings feature a PDF data sheet with more in-depth technical information. Be it a twisted shielded pair cable or another specification, you can then place your order online for quick, convenient shipping.

We've shared more information on this product's construction, applications, and available variants below. Get in touch with our friendly experts if you have any questions.

What are multiconductor cables?

As the name suggests, multiconductor cables are cables with at least two, or potentially many more, conductors for different purposes. They're also known as multicore wire or cable, typically in Europe. The core in multicore refers to the number of usable connections rather than the number of wires, however.

These cables are commonly used for control purposes in signaling, communications and broadcasting applications.

How are multiconductor cables constructed?

Each cable conductor within a multiconductor wire can consist of a single wire or a combination of several that aren't insulated from each other. Multiple combined wires are often referred to as stranded cable. They can be twisted in various ways such as pairs, triads, or concentrical arrangements, with an outer sheath containing and protecting them.

This outer layer can be produced from a range of materials, with the option of an aluminum sheath underneath for electromagnetic shielding. The jacket provides mechanical protection for the multiconductor cable. In some cases, individual cables within the multiconductor have their own jackets for protection too.

Some of these cables terminate in a multi-pin connector, while others split off into several connectors. The overall construction of a multiconductor cable can be determined by temperature, voltage, and environmental factors, as well as its required electrical performance. A multicore armored cable, for example, features steel wire below the sheath to make it even harder wearing.

Shielded vs unshielded multicore cable

The presence or absence of an aluminum sheath within the cable's jacket depends on whether electromagnetic interference is an issue in the cable's intended environment. In industrial settings for example, high-powered equipment may transmit electromagnetic frequencies which could interrupt the signal carried by your multiconductor cable. But you can negate this risk with a shielded cable. This can also be described as a multicore screened cable.

Conversely, unshielded multiconductor cables are usually easier to install and work with as well as being cheaper to buy. So, in applications where electromagnetic interference isn't an issue, it makes sense to opt for an unshielded cable.

What are the other variations of multicore wire?

Multiconductor cables can also vary in size to suit different applications. Their size is measured in American Wire Gauge (AWG) here in the U.S., with higher gauge numbers denoting smaller, thinner wires.

The insulation material used to reduce current leakage can also vary depending on its intended application. The jacket of a multicore insulated cable could be comprised of:

Ethylene Propylene Diene Elastomer (EPDM), which performs well in a wide temperature range.
Neoprene, providing resistance to oil, fire, and chemicals.
Silicon rubber, which is highly flexible.
Thermoplastic such as polyethylene, which offers good insulation with moisture and chemical resistance.
Mica tape, offering extremely high temperature resistance.
