220kV Porcelain insulation outdoor termination
Product Descriptions
● The product uses high-strength porcelain sleeve which has the advantage of high mechanical strength, good stability, no aging, especially suitable for coastal and natural environment harsh areas.
● The product adopts the structure of big and small umbrella skirt, and the experiment has proved that this structure has excellent pollution resistance.
● It has a good sealing performance to prevent flooding, oil leakage and other possible defects.
● Porcelain insulator comes in two sizes. One specification is 1280mm high and 3150mm creepage distance, which is suitable for Ⅲ-level dirty areas. The other specification is 1400mm high and the creepage distance is 3906mm, which is suitable for Ⅳ-level dirty areas.
