The invention relates to the technical field of porcelain insulators, and particularly discloses a primary glaze dipping process of a special head umbrella for ultrahigh-pressure suspended porcelain, which comprises the following steps: S1, preparing glaze into glaze slip from the following raw materials in parts by mass: 10-20 parts of microcline, 10-20 parts of albite, 5-15 parts of high-plasticity clay, 7-12 parts of kaolin, 10-14 parts of calcined talc and 4-10 parts of wollastonite; 15-25 parts of quartz powder, 6-10 parts of zirconium silicate and 2-6 parts of aluminum oxide; and S2, putting the head part and the umbrella part of the blank into the glaze slip, and glazing the head umbrella of the blank at one time in a glaze dipping manner. The glaze slurry used for glaze dipping is contained in the glaze dipping tank, during glaze dipping, the blank is placed uprightly, and the glaze spraying device is arranged below the blank and used for sucking the glaze slurry in the glaze dipping tank and then spr
