As the pillar porcelain bottle is installed in the high voltage circuit, its basic performance should include the electrical performance. And since most of the pillar porcelain bottles are used in the open air, they must also have certain mechanical properties and corrosion resistance. Its electrical performance is mainly reflected in the insulation performance and electrical breakdown resistance of the pillar porcelain bottle . The former is well understood, and the pillar porcelain bottle itself is made of ceramics with excellent insulation properties, so the pillar porcelain bottle fully meets the needs in terms of insulation performance. The latter's resistance to electrical breakdown is mainly due to occasional sharp high voltage sparks, which can actually be called part of the mechanical properties. Porcelain pillars need to have sufficient pressure resistance to ensure that they will not be damaged by occasional electrical sparks. Its mechanical performance is mainly due to the pillar porcelain bottle installed in the open air environment, need to withstand the effects of gravity, wind, earthquake or other mechanical stress. The anti-corrosion performance is the basic performance of ceramics with pillars, the ceramic itself.
