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.

In modern building electrical systems, the performance of wires and cables directly affects the safety and reliability of the entire project. With the expansion of building scale and the increase in electrical load, the performance of traditional PVC insulated wires in high-temperature, humid, or high-load environments is gradually failing to meet the demands. At this point, XHHW wires (Cross-linked Heat and Water Resistant Wire) are used in building electrical systems due to their excellent heat resistance, moisture resistance, and insulation properties.

THWN/THWN-2 wires are widely used in industrial applications, have become the mainstream choice for industrial power distribution and control systems due to their excellent heat resistance, moisture resistance, and chemical resistance.
