insulators

 Why are insulators made this way?

2 Minutes of Electricity

The electrical insulators shown in the picture, especially those with a wavy or curved design, are designed this way for important technical and architectural reasons. 

The main reason behind this design is to reduce electrical leakage and distribute electrical voltage more efficiently across the insulator's surface.

1. Reducing Electrical Leakage:

The wavy or curved design of insulators divides the insulator's surface into small, interconnected sections. 

This technique reduces the voltage across each section, preventing excessive electrical charge buildup in any given area.

2. Resistance to Environmental Influences:

Rain and Dust: The wavy design helps prevent water or dust from accumulating on the insulator's surface.

 If water or dust is present on the insulator's surface, it can lower its electrical resistance and increase electrical leakage.

 The curved design facilitates water drainage and reduces dust retention on the surface.

 3. Increased Service Life:

Improved Durability: The corrugated design distributes electrical stresses and voltages better across the insulator surface, reducing the likelihood of damage or failure under high voltage.

4. Improved Electrical Performance:

Reduced Local Voltage: The corrugated design reduces the concentration of electrical voltage at specific points, reducing the likelihood of sparking or damage to the insulator due to voltage spikes in specific locations.
