3.3.8 Insulation. Insulation, if required, shall be as specified on the applicable specification sheet.
3.4 Components. The cable may include components such as:
a. Shielded single conductors, shielded twisted pairs, shielded twisted triplets, etc. Unless
otherwise specified in the applicable specification sheet, all shielded components shall be
insulated by a component jacket, applied over the shield, to prevent electrical noise and stray
ground currents.
b. Nonshielded twisted pairs, twisted triplets, etc. When specified in the applicable specification
sheet, a component jacket shall be applied over the twisted assembly.
3.5 Design and construction.
3.5.1 Component twisting (cable lay). Twisted components of the finished cable after being laid up
shall have no residual twist on the individual wires. The length of lay shall be between 8 and 16
times the pitch diameter of the layer in the component. Fillers may be used, as needed, to permit
compliance with the roundness requirements specified herein and to modify diameters to fit components
to the finished cable. At the option of the manufacturer, binder tapes (see 3.3.4) may be applied over the
components to assist in further cabling operations.
