introduction:

Composite Post Insulator refers to an insulating device constructed from a combination of advanced polymeric composites, such as epoxy resins or silicone rubbers, reinforced with fiberglass materials, typically in the form of a fiberglass rod core.
Designed for use in electrical power systems, particularly in transmission lines and substations, these insulators serve the critical function of supporting and isolating the conductors from the ground or other metallic components, thereby ensuring that electric current flows solely along the intended conductive path, preventing leakage or short circuits.
The use of composite materials imparts several advantages over traditional porcelain or glass insulators, including higher mechanical strength, better resistance to environmental factors like pollution and moisture, lighter weight, and ease of installation and maintenance.
