1.Design:The "XI shed" refers to the shape of the sheds or skirts on the insulator, which resemble the Roman numeral XI. 

2.Function:

  1)These sheds increase the creepage distance – the path electricity must travel along the surface of the insulator before reaching the ground or another conductor. 

  2)Reinforcement typically means that these sheds are designed to withstand harsh environmental conditions and mechanical stress, improving reliability and longevity. 

3.Advantages:

  1)Increased Creepage Distance:The unique XI shape provides a longer surface path for potential leakage currents, enhancing the insulator's ability to prevent electrical discharges.

  2)Improved Performance in Contaminated Environments:The design helps prevent dirt and pollutants from accumulating, which is beneficial in areas with high pollution levels.

  3)Enhanced Mechanical Strength:The reinforced structure provides extra mechanical stability, making them more resistant to breakage due to environmental or mechanical stresses.

  4)Better Wet Performance:The shed design improves performance under wet conditions, reducing the risk of flashover events.
