Anatomy of a Cable
Multiconductor Cable
Multiconductor cables are a common cable style used for a variety of applications, such as security systems,
home theater audio and thermostats. Let’s explore the components of standard multiconductor cables.
Conductors
Conductors can be solid or stranded and are
made of a variety of materials that eciently
transfer electricity. For most applications,
pure copper is the ideal choice because it has
low resistance at a cost effective price. For
more unique applications, such as exposure
to humid conditions, a material like tinned
copper offers additional advantages.
• Solid Conductors: Allows for clean,
lower-risk terminations at a cost
effective price.
• Stranded Conductors: Greater
exibility reduces the risk of
breakage, for smoother and
more ecient installations.
Ripcord
Used to cut back the jacket to expose the
wires of the cable – reducing the risk of
cutting the wires inside. This makes
splicing and terminating cables easier
during installations.
Jacket
Colored material coating that covers
all of the cable’s components. The jacket
provides physical protection and contributes
to a cable’s re and outdoor ratings.
Insulation
Plastic coating that covers the conductor
and separates it from other cable
components. The material type and
thickness help to determine the cable’s
electrical characteristics.
Shielding
Multiconductor cables are either shielded
or unshielded, depending on the level
of interference.
• Shielded: Reduces electrical interference
and other potential disruptions to
signal integrity. A drain wire completes
the electrical circuit from the shield,
optimizing performance.
• Unshielded: A cost-effective solution
for everyday cabling needs. Optimized
for environments with very little
signal interference.
