What are the application scenarios for composite insulators?
Composite insulators, thanks to their lightweight design, strong resistance to pollution flashovers, and durability in harsh environments, are widely used in power systems and specialized power supply applications.

Porcelain insulators reduce the energy-intensive "high-temperature firing" process, while composite insulators utilize eco-friendly silicone rubber materials, lowering carbon emissions during production.

Used as either "suspension insulators" (for hanging conductors) or "strain insulators" (for securing conductors to towers), these are employed in 10kV–1000kV high-voltage and ultra-high-voltage transmission lines.

Key technical features of insulators: Critical metrics ensuring grid safety
It must withstand power-frequency withstand voltage, operating impulse withstand voltage, and lightning impulse withstand voltage at the rated voltage, ensuring that neither "breakdown" (where the insulation layer is punctured by voltage, leading to conductivity) nor "flashover" (where a conductive path forms on the surface, causing leakage current) occurs.

Power insulators can be categorized into three main types, each with distinct characteristics, advantages, and suitable application scenarios.

The "Insulation Guardian" of the Power System
Primarily used in scenarios such as high-voltage transmission lines, substations, and distribution equipment, its core function is to achieve electrical isolation between conductive elements and grounding bodies.

Insulator Performance Comparison
Insulators are critical insulation components in power systems, used to support conductors and isolate energized parts from non-energized ones. They ensure that current flows only through the wires, preventing leakage or short circuits.
