Nooa Electric U120BP Glass Insulators for Romania

The Cornetu-Tigveni section traverses challenging mountainous terrain characterized by high humidity, fluctuating temperatures, and difficult access for maintenance. The project faced several critical "pain points":

Extreme Environmental Exposure: High altitude and mist in the Carpathian region increase the risk of flashovers.

Maintenance Constraints: High-speed highway environments make frequent maintenance dangerous and costly.

Aging Infrastructure: Existing local lines were insufficient to handle the increased load required by modern highway technology.

Reliability Demands: Any power failure on a major international highway poses significant safety risks to transit.

The Solution: U120BP Glass Insulators

To address these challenges, our U120BP high-strength toughened glass insulators were selected. These insulators are specifically designed for high-voltage environments where mechanical tension and electrical insulation are paramount.

Key Features:

Self-Shattering Property: Allows for easy visual inspection—if a unit fails, it shatters but maintains mechanical integrity, eliminating the need for complex testing.

High Dielectric Strength: Superior resistance to electrical puncture compared to porcelain.

Anti-Pollution Design: The "BP" (Bell-type) profile provides an extended creepage distance, ideal for the foggy conditions of Section 3.

Final Commissioning: Passed all dielectric and mechanical load tests on the first attempt.

Project Results & Impact

The successful application of U120BP Glass Insulators in the Sibiu-Pitesti Highway Section 3 project demonstrates NOOA Glass Insulator's superior reliability and economic value. This project serves as a benchmark for high-stakes municipal and transport infrastructure, proving that NOOA glass insulators are the ideal choice for demanding environments globally.

Q1.What is the special function of the "BP" design of the U120BP insulator? 

A1: "BP" stands for Bell-type, which has a greater creepage distance. It is very suitable for the foggy and humid mountainous environment and can effectively prevent pollution flashover.

Q2.What help does the "self-breaking" characteristic of tempered glass insulators offer for maintenance?

A2: Tempered glass has Self-Shattering properties to maintain mechanical integrity This enables maintenance personnel to easily identify faulty units through ground visual inspections without the need for complex testing equipment, thereby significantly reducing maintenance costs and the risks of live-line operations.

Q3.Compared with traditional porcelain insulators, what advantages does this product have? 

A3: This glass insulator has a more outstanding resistance to electrical breakdown (high dielectric strength)
