90 kn Polymer Disc Insulator

90kN Polymer disc insulator – High Performance, Lightweight, and Built to Last 

The 90 kN Polymer Disc insulator is a new electrical component that is used on overhead transmission and distribution lines. It has a mechanical load rating of ninety kiloNewtons, which makes it a suitable insulator for medium to high voltage applications (with an even higher rating on the sheath). These insulators, when applied in excess of standard voltage / standard weather, provide an excellent performance. If strength, reliability, and resistance to harsh or extreme environments is a design requisite,90 kn Polymer Disc insulator is purpose solve. 

This tool is constructed of state–of–the–art composite materials including fiber-reinforced polymer (FRP), and silicone rubber. These allow for a novel electrical insulator –more representative of modern materials than traditional porcelain or glass insulators. This insulator benefits from high mechanical performance, excellent electrical insulation, and superior weathering resistance due in part to these properties. The resultant insulator is capable of meeting challenges in operating conditions across a wide range of global climates and terrains. 

Key Features 90 kn Polymer Disc Insulator

High Mechanical Load Rating (90kN): These are noted as ideal mechanical loads in tension and suspension string use. 

Lightweight: Far lighter than ceramic or glass, this reduces activity costs associated with shipping/transporting and erecting. 

Silicone Rubber Housing: Hydrophobicity – silicone rubber reduces surface leakage currents and potentially flashover.

Corrosion and UV resistance – allowing for extended life in coastal environments, industrial environments, desert environments, etc. 

Low Maintenance – Long service life beyond 25 years, minimal maintenance. Minimal inspection and cleaning.
