system contains a specially engineered silicone formula that hardens when exposed
to extreme temperatures. As it hardens, the
cable forms a protective layer around the
copper conductor that allows for the circuit
to maintain integrity when under attack.
Comtran introduced a new version of
the VITALink in June. Prior to that, this
circuit integrity cable had to be installed
in conduit, known as VITALink CIC (circuit
integrity in conduit) cable. The newly introduced VITALink circuit integrity (CI) listing
allows the cable to be installed without the
use of conduit - a unique feature. "It's making our existing product more versatile,"
Contractors like using a circuit integrity
cable without conduit because it saves
them time, space and money on labor. If
there's no conduit, there are no conduit fill
restrictions. Also, the VITALink CI is easy to
install and does not require special tools or
training, Braley-Purewal says. The product
is wet-rated and sunlight resistant. It does
not require a termination kit and installs
in accordance with the National Electrical Code (NEC).
Compared to CIC cables that are installed
in a raceway or conduit and listed as an
"electrical circuit protective system" or
"fire-resistive cable system," CI cables are
installed in free air without any protection
of a conduit or raceway.

UL-approved manufacturer that makes its
products in the United States.
Since its inception, the company quickly
grew to be one of the primary manufacturers of data and communication cable in
the Northeast. In 2001, Comtran became a
