33KV 160KN Double-Umbrella Glass Insulator UG160B170/450

Product Overview

The 160kN double-umbrella disc suspension glass insulator UG160B170/450 and the 120kN version, UG120B/146/450D, are highly esteemed in both the Chinese and international markets, including Vietnam, Iran, and Algeria. These insulators are essential components in overhead transmission lines, providing crucial insulation and support for wires.

Structural Composition

Glass insulators consist of iron caps, tempered glass pieces, and steel feet, all bonded together with cement adhesive. They are available in various types, including standard, pollution-resistant, DC, spherical, aerodynamic, ground wire, and contact network types for electrified railways.

Key Features of Double-Umbrella Disc Suspension Glass Insulators

• Anti-Pollution Performance: The double umbrella structure ensures more uniform pollution distribution over the insulator's surface, reducing pollution flashover accidents in heavily polluted areas.
• High Mechanical Strength: These insulators can withstand vertical and horizontal loads, as well as additional loads from severe weather conditions like strong winds and snow.
• Longevity: With excellent pollution resistance and mechanical strength, these insulators offer a long service life, minimizing replacement frequency and maintenance costs.
