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