Abstract
The invention discloses a pin-type porcelain insulator for a line. The pin-type porcelain insulator for the line comprises a zinc sleeve and a porcelain part, wherein an umbrella skirt is arranged on the outer surface of the porcelain part; a brown glaze layer is arranged on the surface of the porcelain part; a step hole is formed in the bottom of the porcelain part; the bottom of the step hole is connected with the zinc sleeve through a cement adhesive; the porcelain part is fabricated by a one-stage molding process; and the overall height of the porcelain part is 246mm. The pin-type porcelain insulator for the line is molded once; (compared with an existing PW-33-Y pin-type porcelain insulator for the line, the weight of each pin-type porcelain insulator is reduced by about 5KG); the pin-type porcelain insulator is good in heat dissipation performance; the creepage distance is increased by about 10%; the cost is reduced; and installation is portable under the condition that the mechanical property and the electrical property are ensured.
Description
technical field [0001] The invention relates to an insulator, in particular to a line pin type porcelain insulator. Background technique [0002] Overhead transmission lines, bus bars of power plants and substations, and external live conductors of various electrical equipment must be supported by needle-type porcelain insulators and insulated from the earth (or ground) or other conductors with potential differences. Both use PW-33-Y line pin type porcelain insulators. The PW-33-Y line pin type porcelain insulators have upper and lower structures, which are complex in structure and difficult to manufacture. Contents of the invention [0003] The purpose of the present invention is to provide a line pin type porcelain insulator to solve the problems raised in the above background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A line pin type porcelain insulator, comprising a zinc sleeve and a po...
