1. Basic concepts and technical features of XHHW Wire
1.1 Definition and naming analysis
The "XHHW" in XHHW wire represents several core characteristics of this type of wire:
X (Cross-linked): refers to the insulation material of the wire being cross-linked to form a stable three-dimensional mesh structure.
HH (High Heat-resistant): indicates that the product has high heat resistance and can operate for a long time in a high temperature environment.
W (Water-resistant): indicates that the product has good waterproof and moisture-proof capabilities, and can maintain stable insulation performance even in a humid environment.
This structure enables XHHW wire to perform better than traditional PVC or other thermoplastic insulation materials in harsh environments such as high temperature, humidity and chemical corrosion.
1.2 Technical features
Strong heat resistance
The cross-linked polyethylene (XLPE) enables XHHW wire to work stably at 90°C or even higher, and is suitable for high temperature environments such as industrial equipment and heating systems.
Waterproof and moisture-proof
The optimized insulation structure and low water absorption design enable XHHW wire to maintain good insulation performance in underground, humid or outdoor environments, reducing the risk of leakage caused by moisture intrusion.
Chemical corrosion resistance
Cross-linked polyethylene materials have excellent tolerance to a variety of chemicals (such as acids, alkalis, and oils), making XHHW wire widely used in corrosive environments such as chemical plants and oil fields.
Excellent mechanical strength and wear resistance
The cross-linked material has high tensile strength and impact resistance, and can maintain a long service life even if it is bent, stretched or mechanically impacted during installation.
Comply with strict international standards
The American market has strict requirements on the safety of electrical products. XHHW wire usually needs to pass international certifications such as UL44 to ensure its stability and safety in high temperature, high humidity and other extreme environments.
