Insulators are essential components used in electrical power systems to support and isolate live conductors from the supporting structure or ground. They play a critical role in ensuring the safe and reliable transmission and distribution of electrical energy. Insulators are primarily used in overhead powerline installations, substations, and various electrical equipment.
The main purpose of insulators is to prevent current leakage and maintain electrical insulation between the conductors and the supporting structures. They are typically made of non-conductive materials such as porcelain, glass, or polymer composites. The choice of material depends on factors such as voltage level, environmental conditions, and mechanical strength requirements.
