摘要： Insulating materials are provided, the insulating materials comprising a nonwoven web comprising a plurality of continuous spunbonded polyester bicomponent fibers. Each of the plurality of bicomponent fibers comprises a) from about 20% by weight to about 80% by weight of poly(ethylene terephthalate) in a core, and b) from about 80% by weight to about 20% by weight of poly(trimethylene terephathalate) in a sheath surrounding the core, wherein the amounts in percent by weight are based on the total weight of each of the plurality of bicomponent fibers. Also provided are electrical apparatuses comprising the insulating materials and a dielectric fluid, as well as a dielectic material comprising the nonwoven web impregnated with at least 10 weight percent of a dielectric fluid.
