is made specifically to permit the use of smaller wire in cables
having a large number of wires and having adequate support
against adverse effects of vibration. The size of wire leads
supplied integral with parts shall be controlled by the speci-
fication for these parts.
3.1.34.1
Insulation on Conductors:
Insulation of the sleeve type may be used, provided its length
is sufficient to prevent slippage along the conductor to such
an extent as to expose a section of the conductor that should
be insulated. Insulation shall provide adequate dielectric
strength and adequate leakage resistance when the equipment is
operated under the designated service conditions. The mechanical
and electrical properties of the insulating materials and impreg-
nating compounds shall not be permanently impaired as a result
of being exposed to extremes of temperatures incurred in the
equipment. Rubber without braid may be used only when the insu-
lation is not depended upon to space or support the conductor,
or when a number of conductors are assembled in the form of
cordage and the assembly provided with a braid covering which
has been suitably varnished or lacquered. All conductor insu-
lation shall be of the non-combustible or slow-burning type;
that is, with the insulated conductor held in a horizontal po-
sition in still air, self-sustained combustion of the insulation
or lacquer shall not progress at a rate in excess of 1 inch in
1 minute.
Wiring (Internal):
3.1.35
Connections within the equipment shall be suitably supported in
3.1.35.1
such manner as to prevent breakage and eliminate change in fre-
quency or output owing to severe vibration and acceleration or
shock encountered under the specified service conditions. The
use of a flexible and a solid conductor in a continuous run with-
out a support at their junction is not acceptable. Solid wire
may be used in the equipment} provided such wire iS so insulated
or held in place that it does not fail or show excessive motion
when the equipment is subjected to the vibration and shock en-
countered under the specified service conditions.
