Overview of the Composite Insulators Market
The  global composite insulators market plays a critical role in ensuring the efficiency, safety,
and  reliability  of  electrical  transmission  and  distribution  systems.  Composite  insulators  are
manufactured using advanced polymer-based materials such as silicone rubber and fiberglass-
reinforced plastics. These materials offer superior electrical insulation, mechanical strength, and
environmental resistance when compared to conventional porcelain or glass insulators.
Composite insulators are widely used to isolate electrical conductors, prevent leakage currents,
reduce flashovers, and ensure uninterrupted power flow across high-voltage networks. Their
lightweight  nature,  ease  of  installation,  and  low  maintenance  requirements  make  them an
attractive alternative for modern power infrastructure projects.
