Multipair Extension Cable
Common extension wire types are made
up into standard multipair cables. Each
conductor is covered with a polyvinyl
jacket, nominal 0.38 mm (0.015") thick,
and the pairs are individually twisted.
Clear polyester film/plastic sheet tape
is then wrapped around the bundle of
twisted pairs. A stranded tinned-copper
drain wire is laid over the bundle, which
is covered with aluminum-backed
polyester film/plastic sheet tape to serve
as an electro-static shield. The drain
wire provides a simple mechanical
termination for the shield. The cable is
then covered with a jacket of polyvinyl
approximately 1.1 mm (0.045") thick.
As an added convenience, each
standard cable contains an extra
polyvinyl-clad stranded-copper
wire for use as a ground connection,
or to complete a communication or
signal circuit. Standard cables are
color-coded. The individual pairs
are marked 1-1, 2-2, etc., for easy
identification. Insulation will withstand
temperatures up to 105°C (221°F).
Note: Metric dimensions are approximate.
