The present application relates to a thermal insulation felt with thermal shock resistance and a preparation method thereof. A thermal insulation felt with thermal shock resistance has a layered structure, and includes a glass fiber layer with filler and a thermal shock-resistant coating, in which the thermal shock-resistant coating is coated on one or two sides of the glass fiber layer with filler. The filler is hollow glass bead or aerogel SiO.sub.2. The thermal shock-resistant coating is obtained by coating a thermal shock-resistant coating material on one or two sides of the glass fiber layer with filler and then drying and solidifying. The thermal shock-resistant coating material, based on a weight percentage, includes 10-50% SiO.sub.2, 5-60% ZnO, 5-40% Al.sub.2O.sub.3, 5-15% poly tetra fluoroethylene, 5-35% silane coupling agent and 15-50% phosphate.

A high-voltage alternate current electric cable [is provided. In the electric cable,] having at least one metallic electric conductor is surrounded by at least one extruded insulating layer. The insulating layer includes from 1 wt % to 30 wt % of a void-containing filler. The filler is made of particles having an average diameter up to 50 pm dispersed in an insulating polymeric material.
