Static on the Radio? How Electrical Interference Can
(ARA) - Navigation and DVD systems, satellite radio and airbags
– have you ever thought about how many electrical cables are in
your car? It used to be just power windows and lights, but with
today’s sophisticated vehicles, the electronic systems have
multiplied.
The typical minivan has myriad electric motors, solenoids,
relays, switches and miles of magnetic-field-producing wiring
strung around its interior that control everything from the power
windows to the engine’s emissions system. All of these systems
operating in close proximity sometimes can cause electrical
interference that will make components malfunction.
“The more electronic devices you put in a vehicle, the more
likely they will interfere with each other,†says Erin Wright of
the systems protection group at Federal-Mogul, an auto component
specialist.
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.
