The glass insulator aerodynamic U120BP-146M is an excellent insulator product designed to cope with extremely harsh operating conditions such as ultra-high voltage, heavy pollution, and strong wind environments. It integrates innovative aerodynamic umbrella design on the basis of traditional anti fouling insulators, achieving breakthroughs in electrical performance, mechanical strength, and environmental adaptability. It is a flagship solution for protecting the safe, stable, and efficient operation of important transmission channels.
Product Features
Aerodynamic Umbrella Design
The contour of the umbrella skirt has been optimized by fluid mechanics to enhance the effect of rainwater erosion and effectively reduce pollution deposition;
In areas with strong winds, it can reduce the rate of pollution accumulation and improve operational efficiency.
Excellent anti fouling performance
Suitable for Class III and above polluted areas (such as chemical industrial areas, coastal areas, and desert edges);
Long creepage distance and high flashover voltage under wet and dirty conditions.
Zero value self explosion characteristic
Tempered glass insulators will automatically break (self destruct) after deterioration (such as internal cracks and aging), making it easy to inspect and identify;
After self explosion, the iron cap and steel feet still maintain a certain mechanical strength to avoid disconnection accidents.
Maintenance free advantage
No hidden defects, no need for regular cleaning or preventive electrical testing;
Transparent glass body facilitates visual inspection of the internal condition.
High mechanical and electrical strength
Good tensile strength, able to withstand composite loads such as wire tension, icing, wind vibration, and earthquakes;
Stable electrical performance, uniform voltage distribution, and reduced risk of partial discharge.
Application scenarios
High voltage/relatively high voltage AC transmission lines (mainly 110kV and 220kV)
Areas with frequent sandstorms, industrial pollution areas, and coastal high salt spray areas
Important transmission channels that are sensitive to line quality and maintenance costs
