U120BP Glass Insulators Powering the LEA 110kV Jilt - Rosiuta Project

As Romania modernizes its high-voltage transmission network, the demand for components that can withstand both industrial pollution and harsh weather has increased. The LEA 110kV Jilt - Rosiuta project is a vital energy corridor in Romania's industrial heartland. To ensure the long-term stability of this 110kV line, NOOA ELECTRIC CO., LTD. - China leading glass disc insulator manufactuer was selected to provide high-performance insulation solutions.

Project Name: LEA 110kV Jilt - Rosiuta (Overhead Transmission Line)

Country / City: Romania, Gorj County (Mătăsari / Motru region)

Voltage Level: 110kV

Project Type: National Grid Modernization & Infrastructure Reinforcement

Glass Insulator Supplier: NOOA ELECTRIC CO., LTD.

Main Insulator type: U120BP Toughened Glass Disc Insulators (Anti-Pollution / Fog Type)

1.Challenges in Gorj County

The Jilt - Rosiuta line operates in a demanding environment characterized by:

High Industrial Pollution: Proximity to the Jilt South and Rosiuta open-pit coal mines leads to heavy dust accumulation on insulators, increasing the risk of flashovers.

Difficult Maintenance: The hilly terrain of Gorj County makes manual testing of every insulator disk extremely time-consuming and costly.

Extreme Weather: The region faces significant temperature swings and heavy snow loads during Romanian winters.

2.NOOA Electric Solution: U120BP High-Performance Glass Insulator

NOOA ELECTRIC provided the U120BP series, specifically engineered for high-pollution zones.

Self-Shattering for Easy Inspection: Our toughened glass features a "zero-value" self-shattering property. If a unit fails, it shatters visibly, allowing maintenance crews to identify issues from the ground without expensive testing equipment.

Anti-Pollution Design: The "BP" profile offers an extended creepage distance, preventing the buildup of conductive paths from coal dust.

High Mechanical Strength: With a rated electromechanical failing load of 120kN, NOOA insulators provide superior safety margins for the 110kV towers.

Zero Aging: Unlike porcelain or composite materials, NOOA glass insulators maintain their dielectric strength throughout their entire service life.

NOOA ELECTRIC managed the supply chain with precision:

Technical Alignment: Coordinated with Romanian grid engineers to ensure 100% hardware compatibility.

Strict Quality Control: Every batch of U120BP underwent rigorous thermal shock and mechanical tension tests at our facility.

On-Time Delivery: Logistic coordination to the Gorj site ensured the project met its strict "grid-window" installation schedule.

Commissioning Support: Provided technical documentation for the successful integration of the strings.

Status: The project was completed with zero safety incidents and passed all Romanian National Grid (Transelectrica/Distribuție) standards.

The LEA 110kV Jilt - Rosiuta project stands as a testament to the reliability and technical superiority of NOOA ELECTRIC glass toughened insulators. By solving the unique challenges of the Romanian energy sector, NOOA Electric has proven once again that our glass insulators are the ideal choice for heavy industrial and high-voltage applications worldwide.
