The characteristic of the standard profile is that the leakage distance is higher than the value indicated for standard insulators in IEC 60305. The insulation part is designed with shallow and well spaced small ribs, which can be effectively self-cleaning by wind or rain.

The fog type profile is characterized by long and widely-spaced under-ribs so as to avoid arc bridging between adjacent ribs. It features a leakage distance/spacing ratio of around 3.2 and is particularly effective in coastal areas (Salt fog) as well as in polluted areas where a higher specific leakage distance is required.

Design of insulating part with open profile is marked by absence of under-ribs and extended diameter of disk, with no under-ribs so as to avoid the accumulation of solid pollution deposits (dust, sand)on its lower surface. Open profile reduces pollutant accumulation on the surface. This design is effective in desert areas with wind and sand storm also can solve ice-bridging problems. It is particularly adapted to suspension and tension applications in desert areas where wind is predominant and rain infrequent. It is also effective for dead-end strings in cases of extreme industrial pollution and can solve ice-bridging problems when it is alternated with other profiles in the string.

The design of the insulation part has two external ribs. The elimination of the under-ribs reduces pollution build-up, and the surface of the insulator can self clean by strong winds. And facilitate manual cleaning when necessary. This profile provides a leakage distance equivalent to the anti pollution profile and adapts to the most extreme cases of solid pollution. Insulators perform well in industrial pollution and saline soil areas.

Triple-shed Type glass insulator is a key component in transmission lines, characterized by three layers of umbrella discs separated from each other on the insulation body. Thanks to this open shed design, they not only achieve self-cleaning during wind and rain, making it difficult for contaminants to adhere, but also provide a longer creepage distance. This results in excellent pollution flashover resistance and stable electrical performance even in harsh environments such as heavily polluted areas, high altitudes, and coastal humid regions. Consequently, they are an important choice for high-performance transmission projects like Ultra-High Voltage (UHV) lines.

By connecting internal or external metal accessories (such as steel feet and flanges) to the grounding wire, reliable grounding can be achieved. The grounding function effectively guides lightning current, reduces line lightning damage, and protects the safety of lines and equipment. The glass surface is smooth and has low hydrophilicity, making it easy to remove dirt
