How thick is the insulation of XHHW 500 kcmil conductors?

The insulation thickness of XHHW (Cross-Linked High Heat Water-Resistant) 500 kcmil conductors is specified to be 1.65 mm. This is important for ensuring that the conductors can withstand the operational conditions they are designed for, including temperature and moisture resistance. XHHW is designed for use in wet or dry locations and has properties that allow it to perform well under various environmental stresses, making the insulation thickness a critical parameter for maintaining safety and ensuring compliance with electrical codes.

The specific thickness of 1.65 mm provides adequate protection, enhances the durability of the insulation, and contributes to the overall performance of the electrical system. Understanding the insulation characteristics is crucial for electricians and engineers in assessing the suitability of cables for specific applications, ensuring both safety and efficiency in installations.
