These insulators are designed for high-tension applications and must meet strict electrical standards. The rod must insulate electricity along its length, and the insulating layer must be firmly attached to prevent any electrical conduction. The insulating cover provides protection against weather, UV rays, ozone, and mechanical stress, and ideally, it should be flexible, halogen-free, and flame retardant.
There are different types of composite insulators for various uses, such as suspension, pin composite insulator, cross-arm, post, bushing, and electric railway insulators.
Advanced molding techniques are used for shed and housing, ensuring a sturdy connection between the core and end fitting. These insulators are lightweight, compact, and resistant to bending and torsion, making them easy to transport and install. They are designed to resist punctures and maintain structural integrity, making them suitable for use in highly polluted areas. They provide reliable electrical insulation for overhead line suspension or tension, offering durability, strength, and ease of installation.
