25kV Railway Composite Polymer Insulator For Train Insulation

These insulators are commonly used in overhead transmission lines, particularly in areas where durability and resistance to harsh conditions are crucial. The "double" aspect might refer to either a twin-unit configuration or the use of double composite materials for enhanced strength and reliability.

This type of insulator is crucial for maintaining the integrity of power lines by providing excellent electrical insulation and mechanical support.

Suspension-Type: This refers to the way the insulator is mounted. It hangs (or suspends) the conductor from a supporting structure, such as a transmission tower, allowing for better distribution of mechanical loads.

Double Composite: This indicates that the insulator is made up of two composite materials, typically involving a core material (often fiberglass or similar) and an external housing made of silicone rubber or other weather-resistant materials. The use of composite materials makes these insulators lightweight, durable, and resistant to various environmental factors like pollution, moisture, and UV radiation.

Polymeric based Composite insulators are extensively used for overhead rail electric traction system; these silicone rubber insulators play an important role in the traction electrification which supply power to the locomotives of train.
