[P]
Pair - two insulated wires of
single circuit associated together.
Pairing - the union of two insulated
single conductors through twisting.
Parallel Cable - two insulated
conductor's side-by-side in a cable.
PASP - Polyethylene Aluminum Steel Polyethylene. provides additional lightning and gopher protection.
PE - Polyethylene.
Peak Voltage - the maximum instantaneous
voltage.
Percent Conductivity - conductivity
of a material expressed as a percentage of that
of copper.
Periodicity - The uniformly spaced
cable impedance variations that result in addition
of the reflections of a signal. The distance between
them is the half wavelength most affected. Multiples
of that frequency is also affected. Even very slight
variations, which appear over and over in a construction
or installation, can have major effects on signal
integrity because of periodicity.
Permittivity - see dielectric
constant
PIC - Plastic Insulated Conductor. Provides strong insulation.
Pick - distance between two adjacent
crossover points of braid filaments. The measurement
in picks per inch indicates the degree of coverage.
Pitch - Nominal distance from
center-to-center of adjacent conductors within a
cable. When conductors are flat, pitch is usually
measured from the reference edge of a conductor
to the reference edge of the adjacent conductor.
Spacing.
Pitch Diameter - diameter of a
circle passing through the center of the conductors
in any layer of multiconductor cable.
