What types of insulators are commonly used in overhead distribution lines, and how do they impact equipment choice?
2025-08-13The choice of insulator type is crucial for a distribution line's performance and safety. The most common types are:
-
Pin Insulators: Used for voltages up to 33kV, they are simple and cost-effective, mounted on the cross-arm with a pin.
-
Shackle Insulators: Used for low-voltage distribution lines, they are mounted horizontally on poles or cross-arms and are ideal for handling changes in line direction.
-
Suspension Insulators: While more common for high-voltage transmission, smaller suspension insulator strings are sometimes used in distribution to provide flexibility and better performance.
The type of insulator dictates the specific tools and accessories required for installation and replacement. For example, installing pin insulators requires different clamps and fittings than working with suspension strings. Our product line includes a wide variety of specialized tools, from lifting slings and winches to conductors and accessories, ensuring that our customers have the right equipment for any type of insulator or project, regardless of its specific design requirements.
