Introduction

Belden® multi-conductor cables are manufactured in a wide
variety of gage sizes, dimensions, insulation materials, shielding
configurations, and jacketing materials including Plenum and
High-Temperature versions. These cables meet the technical
requirements of many different types of systems. In fact, Belden
offers one of the broadest lines of UL Listed, NEC and CEC
multi-conductor cables available from any single source.
　

Applications for multi-conductor cables include computers,
communications, instrumentation, sound, control, audio, and
data transmission. Each of these cables is designed to protect
signal integrity under critical conditions by reducing hum, noise,
and crosstalk.
　

To assist you in selecting the proper cable for your application,
both the suggested working voltages and the maximum temperature
ratings are indicated for each applicable product in this section.
　

Most of our multi-conductor cables are available from stock. Many
of these are available off the shelf from distributors. If you have a
new or unusual application or you cannot find a multi-conductor
cable in this catalog section that meets your technical requirements,
contact Technical Support at 1-800-BELDEN-1.
　

Multi-Conductor Cables Packaging
Belden’s unique UnReel® cable dispenser is available for many of
the multi-conductor products listed in this section. The letter “U”
before the specified put-up length denotes UnReel packaging
