Here are some key details:
1.Design: These insulators are designed with a sufficient creepage distance to prevent electrical leakage. They are simple to build and require very little maintenance.
2.Applications: They are used for the high-voltage distribution line. They have the flexibility to be utilized in both vertical and horizontal orientations.
3.Voltage: The increased size, weight, and cost of pin insulator put a limit to its use above 66kV. Therefore, the suspension insulators are used for high voltage work.
4.Types: High voltage pin insulators include P-6T (M), P-10T (M), PQ-10T (M), P-15T (M), P-20T (M), PQ-20T (M), P-35T (M) and other models.
