ABSTRACT:
An electrically insulating, overcoated bulky sleeve is disclosed comprising a tubular sleeve prepared from bulky (i.e. low density, high surface area) continuous filament yarns and an overcoating. When an electrical conductor is positioned therewithin, the large surface area of the bulky yarns of the interior of the sleeve provides an intimate fit for an expanded range of conductor diameters. For applications where a void-free impregnation of the sleeve interior between the overcoating and the conductor is desired, the large interior surface area of these sleeves can promote retention of the impregnation composition. The overcoated sleeve can be expandable, deforming to allow pull-back and return or fold-over, and/or conforming to accept transitions in conductor diameter. The overcoated bulky sleeve can be employed in a method for electrically insulating a conductor, which method may further include an interstitial impregnation step.
