Porcelain Electrical Insulators

The porcelain electrical insulators main purpose is to offer dependable electrical insulation and extend creepage distance.
These insulators are typically manufactured from ceramic (porcelain) or silicone rubber materials, and are collectively referred to as electrical insulators.
In overhead transmission systems, insulators perform two basic functions: supporting conductors mechanically and preventing electric current from flowing to ground.
They must be capable of withstanding flashover and electrical breakdown caused by environmental changes and varying electrical load conditions, as any failure may seriously affect the safety and service life of all of the transmission line.
Porcelain electrical insulators are characterized by high mechanical strength, low performance dispersion, and stable, reliable operation.
They maintain excellent mechanical performance under low-temperature conditions, offer outstanding pollution resistance, high seismic resistance, and low radio interference, ensuring long-term operational reliability.
Substation and Distribution Systems
In substations and power distribution systems, porcelain electrical insulators are widely used to support high mechanical loads, with voltage ratings up to 500 kV, meeting the stringent requirements of high-voltage and extra-high-voltage applications.
