In this Letter, we report the dielectric breakdown properties of a nano-composite, which is a potential electrical insulation material for cryogenic high voltage applications. The material is composed of a high molecular weight polyvinyl alcohol and nano-sized, {\em in-situ} fabricated titanate particles. The dielectric breakdown strengths of the filled materials, measured at liquid nitrogen environment, indicate a significant increase of the strength compared to unfilled polyvinyl alcohol. Nanometer sized particles can be adopted as voltage stabilization additive.
