Insulators are fundamental to safe and efficient power distribution in utility networks. They prevent the flow of electricity into non-target areas, ensuring that power is transmitted through the designated pathways. Insulators come in various materials, including composite, glass, and porcelain. They're designed to withstand high voltages and adverse weather conditions, ensuring the reliability of the power transmission system. The choice of insulator depends on the voltage level, environmental conditions, and specific requirements of the utility network.
