The invention discloses a high-voltage-resistant power transmission pipeline material.The high-voltage-resistant power transmission pipeline material is prepared from, by mass, 100 parts of cement, 150-300 parts of ultra-fine aggregate, 5-50 parts of superfine powder, 15-40 parts of macromolecule emulsion, 0.5-1.0 part of water reducer, 0.05-0.1 part of defoaming agent and 0.02-0.08 part of fiber in a mixed mode.Through reasonable composition design, the prepared high-voltage-resistant power transmission pipeline material has the advantages of being high in strength and insulating performance, resistant to high temperature, good in durability, resistant to abrasion and chemical corrosion and high in permeating resistant and elasticity modulus and achieving easy heat dissipation; the problems that an organic polymer material of a traditional power cable dissipates heat slowly, the cable ages at high temperature, and insulation deteriorates can be effectively solved, the loss of power transmission is avoided, the using durability of the product is improved, and economic cost is lowered.
