The invention discloses a clavate suspension-type porcelain insulator with steel caps of different shapes, comprising a solid porcelain body and metal caps sheathed on two end parts of the solid porcelain body, wherein five layers of ribs are arranged in the middle of the solid porcelain body with equal space, and five layers of ribs have same diameter; a pair of hangers extend outwards from the outer end of one metal cap axially, and a hanger extends outwards from the outer end of the other metal cap axially. The clavate suspension-type porcelain insulator can avoid bridge connection among ribs by rain or sleet and has favourable self-cleaning property, and creep age distance reaches 350 mm, thus strengthening pollution flashover preventing property; meanwhile, the solid porcelain body adopts high-strength batch formula, thus effectively improving mechanical tension breaking strength; mechanical tension rated strength can reach 45kN; the metal cap is in a cementing structure sheathedoutside two ends of the solid porcelain body so as to prevent from producing zero by insulation; lightning impulse withstand voltage is 140 kV, thus improving insulation property and performing an important role in lightning protection and line safe operation.
