The Conical Insulator is a durable and reliable electrical insulator designed to provide excellent support and insulation for bus bars and conductors. Manufactured using high-grade DMC/SMC materials, it ensures mechanical stability, high dielectric strength, and long-lasting performance in harsh electrical environments.
Widely used in panels, switchgear, substations, and distribution systems, conical insulators play a key role in enhancing safety, reliability, and efficiency of power distribution networks.
Description
A Conical Insulator is a high-strength electrical insulating component designed in a cone shape to provide mechanical support and electrical insulation for bus bars, conductors, and switchgear assemblies. Its conical structure ensures stability under mechanical stress and fault currents, making it ideal for low and medium voltage applications.
Usually manufactured from DMC, SMC, or epoxy resin, conical insulators are used in panels, substations, and distribution systems where safe and reliable insulation is essential.
