Electromagnetic interference (EMI) is a persistent concern in newer vehicles with multiple electrical systems. This is the disruption of one electronic device caused by a nearby electronic device. “Static on the radio is a common example of EMI. Something is interfering with the system, and the signal is disrupted,” Wright explains. This disruption could be troublesome if it interferes with a critical system.
There is now an innovative new component available for auto manufacturers that will alleviate this problem. TwistTube 2470, developed by Federal-Mogul, offers an effective way to shield car wiring systems from electromagnetic waves. The first textile-based EMI product, it can be easily wrapped around wires to provide lightweight and flexible protection from electromagnetic interference and other damage.
Until recently, most manufacturers used a foil-based product to protect wires. But it was difficult to install and the material’s lack of flexibility and frequent tearing often left cables exposed. The new complex engine environment demanded a better solution.
“TwistTube 2470 is flexible, lightweight and tear-resistant, and therefore easy to install,” says Wright. “It also extends the life of components because it does a good job of protecting cables from abrasion,” she adds.
TwistTube is durable as well and was developed with the harsh engine environment in mind. Unlike similar foil-based products, it can withstand extreme temperatures and is not affected by typical automotive fluids.
The newest version of TwistTube is currently being used to prevent EMI in a wide range of vehicles. For more information, go to www.federalmogul.com.
