XHHW wires utilize XLPE cross-linked polyethylene insulation, boasting exceptional dielectric strength and chemical resistance. This allows them to maintain stable performance in harsh industrial environments, including high-temperature, high-humidity, and corrosive gas conditions. They operate stably for extended periods in dry or humid environments up to 90°C and withstand short-term temperatures up to 125°C, demonstrating excellent heat resistance. Furthermore, XHHW wires offer significant moisture and mildew resistance, maintaining good insulation even in coastal areas or underground installations. They also possess high mechanical strength and abrasion resistance, resisting the effects of tension, bending, and mechanical vibration, making them ideal for heavy-duty or high-intensity industrial applications.

Airport cables are specialized cables designed for the complex and demanding operating environment of airports, used to transmit power and signals under conditions of high security and reliability.
