Hollow Core Insulator Market Segment Insights


Hollow Core Insulator Market Material Insights


The Hollow Core Insulator Market is segmented based on material into polymer, porcelain, and composite. Of these, the polymer segment is likely to account for the highest market share in 2023 and is expected to be the leading segment for the duration of the forecast period. The increased demand for lightweight, high-durability insulators in various applications, such as power distribution and transmission lines, has seen widespread adoption. Demand for polymer insulators is on the rise also because they offer higher electrical resistance, require lower maintenance, and are more cost-effective than porcelain insulators that have been traditionally used in the power industry.There is high demand for the porcelain segment, too, because they have been popular in the industry for the last many decades as they have high electrical insulation, mechanical strength, longer and maintenance-free life, and perform well under extreme weather conditions. However, growth is likely to be curtailed in some of the sub-segments because of the increasing adoption of polymer insulators because of their added advantage of lower costs. In the meanwhile, the composite segment is likely to register steady growth because they combine the benefits of the other two segments, that is, it has high mechanical strength and offers superior insulation.There is increased demand for composite insulators because they heighten the performance of high-voltage applications, making them very popular in the segment. The  Hollow Core Insulator Market is expected to grow at a substantial rate during the period from 2018 to 2023 as the need for more reliable and efficient power distribution, and transmission has increased because of the increased usage of electricity in a variety of forms in the present times, and with greater emphasis on reduction of carbon emissions and adoption of renewable power sources, such as solar and wind power.
