Glass cloth insulation is particularly suited for applications involving high temperatures due to its ability to withstand elevated heat levels without degrading. This type of insulation can typically handle temperatures well above those managed by standard plastic or vinyl insulations. Its composition makes it resistant to thermal degradation, ensuring durability and performance in extreme conditions.

In contrast, vinyl and plastic insulations have lower heat resistance and may start to melt or lose their insulating properties at elevated temperatures. Rubber insulation, while able to withstand moderate heat, does not provide the same level of thermal stability as glass cloth. Therefore, glass cloth insulation is the preferred choice in high-temperature installations, ensuring safety and reliability in electrical systems exposed to extreme environments.
