Professional anti-fouling design, excellent insulation performance: The creepage distance of the product has been increased to 432mm, which is much higher than that of ordinary 11kV insulators. The anti-fouling glaze surface is hydrophobic and resistant to accumulation of dirt. There will be no flashover faults in Class II and Class III polluted areas. The power frequency breakdown voltage is 150kV, ensuring stable power supply in polluted environments.
Reliable mechanical performance, strong resistance to weathering and damage: The cantilever breaking strength reaches 11kN, which can withstand external forces such as strong winds, icing, and conductor tension. The porcelain body is fired at 1350℃, with high density and excellent sealing performance. It is resistant to acid and alkali and corrosion, and suitable for a wide temperature range of -40℃ to +80℃.
Standardized structure, high installation adaptability: The product size is compatible with the common interface of 11kV distribution poles. It can be installed horizontally or vertically, and no additional customized accessories are required. The porcelain parts and metal accessories are bonded using a high-strength bonding process, with excellent sealing performance, suitable for various terrain and polluted scenarios such as plains, hills, and suburban areas for erection.

Urban-rural and township dirty-type 11kV overhead lines: Widely used in urban-rural junctions and beside township roads where dust and smoke are likely to occur, for 11kV overhead distribution lines.
11kV distribution lines around industrial plants: Applicable to 11kV distribution lines around chemical, building materials, metallurgy and other industrial plants.
11kV power grid in coastal and foggy areas: Targeted at 11kV distribution networks in coastal areas with high salt fog and in southern regions with frequent fog and high humidity, which are prone to condensation and accumulation of dirt. The product's water repellent and anti-fouling characteristics can effectively prevent the attachment of salt fog and water vapor, enhancing the line's anti-fouling ability and reducing power supply failures caused by harsh environments.
11kV distribution lines in agricultural planting areas: Applicable to 11kV distribution lines in greenhouse planting, livestock breeding and other agricultural planting areas, capable of withstanding dust and water vapor produced by agricultural production, and suitable for complex environments in fields and outdoors.
