The invention provides a low-temperature-resistant high-voltage power transmission porcelain insulator and a preparation method thereof. The porcelain insulator comprises a porcelain part of the porcelain insulator. The porcelain part of the porcelain insulator comprises the following raw materials: aluminum oxide, calcined bauxite, potassium feldspar, a zirconium dioxide/kaolin composite material, fluorapatite, cerium oxide/lanthanum oxide-coated nano-boron nitride and a sintering aid. A reinforcing layer and a self-cleaning layer are sequentially arranged outside the porcelain part of the porcelain insulator. A coating for the reinforcing layer is prepared by mixing the following raw materials: nano-aluminum oxide sol, a cerium oxide/SiO2-coated graphene oxide composite material, aluminum dihydrogen phosphate, nano-attapulgite and nano-boron nitride. A coating for the self-cleaning layer is prepared by mixing the following raw materials: lanthanum/cerium co-doped titanium dioxide sol, nano-aluminum oxide sol, acicular wollastonite and tetrapod-like zinc oxide whiskers. The porcelain insulator prepared in the invention has good weatherability, is suitable for long-term use in extremely cold areas, and has strong anti-pollution performance and excellent mechanical properties.
