The insulator is one of the electrical insulation equipment used to preserve and isolate the conductors under voltage. This electrical insulation is necessary for power systems to provide reliability.
Application of insulators in the electrical industry
The main application of insulators is in electric substations, transmission lines, and electrical panels, where different insulators with unique shapes are used according to the atmospheric conditions, pollution, humidity, tolerable voltage, conductor weight, and other similar cases.
Application of insulation in high voltage systems
In power transmission lines, it is necessary to isolate the conductor under voltage from the column (tower); high voltage insulators are used.for this isolation The main task of high voltage insulators is to isolate the conductor from the tower without having a leakage current. Also, the insulators must withstand the mechanical force applied by the weight of the conductor and the incoming forces due to atmospheric conditions.
The type of high voltage system insulators
Insulators used outdoors for transmission lines and power stations are made of porcelain, glass, and composite materials. According to the voltage and environmental conditions, they use insulators with suitable materials.
