Numerical Analysis on Surface Temperature of Polluted Porcelain Insulator by Laser Cleaning
2020 5th Asia Conference on Power and Electrical Engineering (ACPEE), 2020The fouling phenomenon of the insulation equipment outside the substation will affect the safety and reliable operation of the substation. Traditional cleaning methods have been unable to meet the requirements.

Vacuum Evaporation of Porcelain Mixture in Production of Porcelain Insulators
Glass and Ceramics, 2005The process of vacuum evaporation of porcelain mixtures on vacuum presses and the ways for improving the production of porcelain insulators are considered. A calculation of unit molding pressure is proposed; the pressure distribution along the press and depending on the moisture of the mixture is indicated.

Investigation of Porcelain Insulators at High Altitudes
Transactions of the American Institute of Electrical Engineers, 1946The use of high voltage apparatus in military aircraft made it necessary to obtain flashover data on capacitor bushings at altitudes up to 50,000 feet. Some of the more pertinent data are presented in this paper which gives a-c and d-c flashover voltages for porcelain bushings having spacings of 5/8 inch to 2 7/8 inches from cap to ring. The tests were

Machine molding of porcelain pin insulators
Glass and Ceramics, 1999A new method for molding porcelain pin insulators used as insulation for cables of low-voltage power lines is suggested. A machine for molding TF-20 inslators is described. A set of technological equipment for mini-production units of low and medium capacity is presented. The technical parameters of the set of machinery are given.

A solution of the porcelain insulator problem
Journal of the American Institute of Electrical Engineers, 1921MANY YEARS ago porcelain insulators on transmission lines began to crack in great numbers. In the earlier cases a few disks in many strings had cracked before the transmission engineers had discovered the condition. Indeed, there was at that time no reason to believe that insulators would deteriorate in any way.

Development of the Porcelain Insulator
Transactions of the American Institute of Electrical Engineers, 1931Porcelain insulators have been manufactured and used for the transmission of high-tension electric power for forty years. The first designs were of the single-piece and multipart cemented pin type. Necessity for higher safety factors against flash-over and increase in operating voltages demanded a rapid increase in the size of the insulators.

Dielectric behaviour of polluted porcelain insulators
IEE Proceedings - Generation, Transmission and Distribution, 2001The dielectric behaviour of polluted porcelain insulators is investigated by means of experimental tests and simulation methods. The elaboration of the experimental results, using well known mathematical models of polluted insulators, leads to the identification of the arc constants.

Corrosion Behavior of Galvanized Steel for Porcelain Insulator’s Pin in HVAC Transmission Line
Key Engineering Materials, 2019The corrosion behavior of galvanized steel in corrosive media of simulated concrete pore solution (SPS) with and without NaCl has been studied for applying it to porcelain insulator’s pins in high-voltage alternating current (HVAC) transmission line.

Countermeasure against explosion of gas insulated porcelain bushing
IEEE Transactions on Power Delivery, 1989In order to investigate countermeasures against the explosion of gas-insulated porcelain bushings, full-scale explosion tests using actual porcelain bushing shells were conducted. Suitable countermeasures are gas volume reduction, gas pressure reduction, and elastic lining methods.
