69kV Horizontal Line Post Insulator (Polymer Type) – With Aluminum Gain Base

 

SEO 2

 

Designed for overhead transmission systems, the 69kV horizontal line post insulator is a durable polymer line post insulator.
It is made up of hot-dip galvanized steel end fittings, an excellent silicone rubber housing, and a bearing solid fiberglass core rod. In addition to being lightweight and simple to install, the design provides excellent mechanical and electrical performance.

This polymer-type insulator is excellent for applications needing high stability and long-term reliability because it is specifically designed to handle cantilever, tensile, and compressive loads.

 
 
Technical Description
Core Rod Diameter 70 mm solid fiberglass core
Structure silicone rubber housing, end fittings, and a cylindrical insulating core
End Fittings Hot-dip galvanized cast or forged steel
Base Type Aluminum gain base
Orientation Horizontal clamptop design, standard leak distance
Application 69 kV transmission lines installed on the cross-arms of poles or towers

Strong attachment on steel or wood cross-arms is ensured by the Aluminum Gain Base, which provides precise position and durable mechanical support.
