U160BL/170 Standard Suspension Glass Insulator
The U160BL-170 standard suspension glass insulator is a 160kN class disc suspension insulator designed for overhead transmission lines and high voltage power transmission systems. It provides reliable electrical insulation and mechanical support between conductors and transmission towers, making it suitable for standard operating environments with normal pollution levels.
Manufactured with tempered glass and high-strength metal fittings, the U160BL-170 suspension glass insulator offers stable mechanical performance, excellent outdoor durability, and easy maintenance characteristics. The transparent glass structure allows operators to visually identify damaged units after failure, improving inspection efficiency during transmission line maintenance.
The U160BL-170 glass disc insulator is commonly used by power utilities, EPC contractors, and transmission equipment suppliers for new line construction, grid expansion projects, and replacement applications where a reliable standard suspension solution is required.

The U160BL-170 provides a balanced solution between electrical insulation performance and mechanical strength for general transmission applications.
Compared with some traditional insulation solutions, glass insulators allow easier failure identification through visible glass damage, helping reduce inspection time.
U160BL-170 is mainly used in overhead transmission lines as a suspension component that provides electrical insulation and mechanical support between conductors and towers.
160kN refers to the mechanical failing load rating of the insulator. It indicates the maximum mechanical force the product can withstand during standardized mechanical testing.
U160BL-170 is a standard suspension glass insulator designed for normal environmental conditions, while U160BP-170 is an anti-pollution version designed for areas with higher contamination levels.
The selection depends on the local pollution severity level. For coastal areas with high salt contamination, anti-pollution glass insulators with increased creepage performance are generally considered.
Yes. U160BL-170 can be supplied for utility projects, EPC contracts, and distributor orders with customized packaging and project support.
