Determining the Shape of a Custom Coil Cord

Determining the Shape of a Custom Coil Cord

The shape of a custom coil cord is one of the most important elements when designing this type of cable.

Custom coil cord is known for its flexibility, making it the perfect choice for applications that require a cable that can stretch and retract without putting additional stress on the wire. It has the ability to extend beyond the natural length at rest, which can be a real space-saving feature. These cords are flexible beyond simple extending and retracting in that they can also be pulled, bent, and twisted without experiencing the metal fatigue of a straight cable.

Coiled cable can be used to carry electrical currents as well as data and signal for telecommunications applications. This versatility makes coil cords ideal for use in environments that are often too rough for non-coiled cable. Coil cords are used in everything from equipment on industrial and construction sites to portable electronics, like sound equipment. With so many applications at so many different sizes, the shape of your custom coil cord is key to its successful performance.

Requirements Determine the Shape of Coiled Cable

If you’ve ever seen a telephone cord, you’ll recognize the shape of a coiled cable – curled in the middle with a section of straight cable at each end. While the specifications of the straight sections are important to the overall function of the cable, it is the coiled section that provides the cord with its unique benefits. The retracted length of the cord is how long it is at rest. This is the most common way to specify how long the cord should be. However, it is also necessary to communicate the full length the cord must extend to, so the engineers at your custom cable manufacturer are able to get a full understanding of the requirements of your cable.

The coil’s diameter is a key measurement when determining how far a custom coil cable should extend. In general, a coil with a larger outer diameter with stretch farther than a coil with a smaller outer diameter. When discussing your cable’s specifications with your cable manufacturer, retracted length, extended length, and outer coil diameter will provide a good starting place for the designer regarding the cable’s physical shape.

Fine-Tuning a Cable’s Performance

While you may be able to get pretty close to the final shape of your custom coil cable on your own, the cable’s construction and materials are best selected with the help of an experienced wire and cable manufacturer. Selecting specific fillers and jacketing materials can also add durability to the finished cord. Depending on how tough you need your cable to be, materials can include:custom coil cord

  • PU
  • PTEE
  • TPR
  • SVO
  • SJOW
  • Kevlar®
  • Spectra®
  • Teflon®

An expert cable manufacturer like Meridian Cable, learns everything they can about how your coil cable needs to function. This allows them to make the best recommendations on the materials and physical shape to ensure the finished cable meets the needs of your product or equipment. Rest assured that no matter what your application, a custom coil cord solution can be designed and produced to perfectly match your specifications.
