Purpose of post insulators

 Purpose of post insulators are supporting and insulating wires or conductors in the electrical systems. Post insulators are one of electrical insulator used on transmission and distribution power lines.

Purpose of post insulators

Purpose of post insulators has main two types in the electrical systems
◆ Line post insulator: used on transmission and distribution power lines
◆ Pin post insulator: used on distribution overhead lines
◆ Station post insulator: used in substations, stations, electrical equipment
◆ Hollow core post insulator: used in substations, stations and transformers etc.

Purpose of post insulators is used in electrical systems consisting of porcelain units and end fittings or silicone rubber weathersheds and end fittings.

Post insulators can be divided into porcelain insulators and polymer insulators for electrical systems.

Porcelain post insulators can be used with high mechanical strength and long service life and avoid be destroyed by the animals.

Polymer post insulators can be used in any contamination level environment with self-cleaning for overhead power systems.

Purpose of post insulators plays two roles of supporting and insulating for transmission and distribution systems with good mechanical and electrical properties.
