Double umbrella glass insulators Features:

Dood insulation performance: Double umbrella glass insulators have excellent insulation performance, which can effectively prevent current leakage in high-voltage power lines and ensure the safety and stability of power transmission.

High mechanical strength: high mechanical strength, able to withstand large tensile force and pressure, suitable for a variety of harsh environments.

Good corrosion resistance: the glass material has good corrosion resistance and is not easily affected by the external environment, which prolongs the service life of the insulator.

Smooth surface and easy to clean: the insulator surface is smooth, not easy to accumulate dirt, reducing the flashover accident caused by dirt.

Beautiful and generous: in appearance, double umbrella glass insulators usually show transparent or translucent state, beautiful and generous.

Double umbrella glass insulators Application:

High-voltage power line double umbrella glass insulators are widely used in high-voltage power lines to isolate high-voltage power lines from grounded parts such as towers and prevent current leakage.

Harsh environment: due to its high mechanical strength and good corrosion resistance, double umbrella glass insulators are especially suitable for harsh environments, such as seashore, chemical plants and other corrosive places.

Urban power grids: Double umbrella glass insulators are also widely used in urban power grids to improve the stability and safety of power transmission.
