Relationship Between Insulator Structure And Insulation Performance

A well-designed polymer deadend insulator body shape, electric field distribution, and surface geometry configuration significantly impact maintaining good electrical isolation conditions; these factors work together to determine insulation performance.

In engineering design, adjusting the geometric parameters of suspension insulator can optimize the electric field distribution, reduce the local electric field enhancement region, and thus improve the withstand capability of suspension composite insulator under different voltage levels. Some studies have clearly shown that adjusting the shape parameters of the composite suspension insulator timer can achieve a better structural electric field state under the same insulation distance conditions.

polymer suspension insulator Surface and internal defects also significantly affect performance. Common defects in basin insulators used in GIS equipment, such as surface depressions or small air gaps, can lead to localized electric field distortion. This distortion can cause electric field concentration under high voltage conditions, thereby reducing insulation levels and affecting the overall reliable operation of the equipment. Practical engineering evaluation methods even use finite element analysis to quantify the electric field changes caused by these design flaws.
