REVIEW

Application

The overhead line Polymer Tension Insulator PTI-1-400 is primarily used in power transmission and distribution networks due to its high performance and durability. Here are the key applications:

Applications:

● Overhead Power Lines:Used to support and insulate high-voltage conductors in overhead transmission lines, especially in tension or suspension locations.

● Long Span Installations:Ideal for insulator strings in long-span situations where mechanical strength and weather resistance are critical.

● Tension Guy Insulator:Employed as tension insulators in guyed transmission towers to withstand mechanical loads and environmental stresses.

● Switching and Substation Applications:Can be used in equipment and substations requiring tension insulators to support conductors or busbars.
