Key Selling Points
- Unique double-umbrella structure greatly increases creepage distance and improves pollution flashover performance.
- Effectively prevents ice bridging and rain flashover in heavy rain, freezing and high-humidity areas.
- Open profile reduces dust and dirt accumulation, lowering maintenance frequency.
- Damaged insulators can be easily identified from the ground, reducing inspection cost.
- Made of high-quality tempered steel fittings with hot-dip galvanizing, durable and corrosion-resistant.
Product Description
Premium Double Umbrella (Double Shed) Disc Suspension Glass Insulators are specifically engineered for overhead transmission lines in heavy pollution, high humidity, heavy rain and icing environments — addressing the core pain points of grid instability in harsh weather conditions. Compared with standard insulators, the unique double-shed design delivers a longer creepage distance and superior antifouling performance without increasing the overall string length. It effectively suppresses flashovers caused by salt fog, industrial dust, rain cascading and ice accumulation, making it an ideal choice for coastal areas, industrial zones and severe weather regions in Southeast Asia, Africa and other global markets. Compliant with IEC 60383 international standards, these insulators are available in the U70D, U120D, U160D series. Crafted with high-quality tempered glass discs and hot-dip galvanized steel caps & pins, they ensure stable electromechanical performance and an extended service life. The built-in self-shattering feature simplifies maintenance, allowing for quick and efficient inspection without the need for complex equipment.
