Core wrap.
(1) The core shall be completely covered with a layer of nonhygroscopic and nonwicking dielectric material. The core wrap shall be applied with an overlap.
(2) The core wrap shall provide a sufficient heat barrier to prevent visible evidence of conductor insulation deformation or adhesion between conductors, caused by adverse heat transfer during the jacketing operation.
(3) Engineering Information: If required for manufacturing reasons, white or uncolored binders of nonhygroscopic and nonwicking material may be applied over the core and/or core wrap.
