Optimized umbrella structure and anti-flashover capability: XHP-70 (U70BP) adopts an innovative streamlined three-umbrella structure, with the deep-angled large umbrella skirt (bell-shaped umbrella) design being its core feature. This structure effectively blocks rainwater bridging and maintains a high insulation resistance in adverse weather conditions.
High mechanical strength and long-term reliability: The product's rated mechanical load reaches 70kN. It is manufactured using high-strength porcelain materials and is equipped with a reliable ball socket connection structure and high-quality metal accessories. This ensures the structural integrity under extreme wind loads, ice loads, and long-term vibration, providing long-life, maintenance-free mechanical support for the lines.
Economy and adaptability: As a standardized product, XHP-70 (U70BP) combines high performance with good economic efficiency. It is an ideal choice for new lines and the upgrade of old lines for anti-flashover.

High-pollution area high-voltage overhead power transmission lines: Widely used in industrial heavily-polluted areas such as chemical parks, steel mills, and mines, as well as 10kV and above AC overhead power transmission lines in coastal salt-spray areas and suburban dusty areas, to solve the problems of traditional insulators being prone to pollution flashover and insulation performance degradation.
High-humidity, heavy fog and high-altitude power transmission lines: Applicable to rainy season areas, mountainous areas with heavy fog and high humidity, and high-voltage power transmission lines above 1000 meters in altitude.
Special environments and line renovation projects: Particularly suitable for high-altitude areas, foggy and humid areas around reservoirs, and anti-pollution flashover technology renovation projects of existing lines.
