Key features of the U120B Glass Electric Insulator:

1. Mechanical Strength: The U120B has a minimum mechanical failing load of 120 kN and a minimum mechanical residual strength of 96 kN, making it suitable for supporting heavy conductors and withstanding environmental stresses.

2. Hydrophobic Surface: Glass insulators naturally repel water, reducing the risk of surface leakage currents and flashovers in wet conditions.

3. Electrical Properties: It has a puncture voltage in insulating medium of 130 kV, dry lightning impulse withstand voltage of 110 kV for a single unit, and wet power-frequency withstand voltage of 40 kV for a single unit.

4. Aging Resistance: Glass does not age or degrade significantly over time, maintaining its insulating properties throughout its service life.

5. Dimensions: The insulator has a diameter of 255 mm for the insulating part, a spacing of 146 mm, and a nominal creepage distance of 330 mm.

6. Self-Cleaning: Due to their smooth surface, glass insulators are less likely to accumulate dirt and contaminants, which can otherwise lead to leakage currents.

7. Standards Compliance: U120B insulators are manufactured in accordance with IEC standards, ensuring quality and reliability.

8. Environmental Resistance: These insulators are designed to operate in temperatures ranging from -40°C to +50°C, making them suitable for various climatic conditions.

9. Zinc Coating: The metal parts have a zinc coating mass of not less than 600 g/m2, providing corrosion resistance.
