XHHN in wire specification means?
Correct Answer
Moisture and Heat Resistant-Cross-Linked Thermosetting
Explanation
XHHN in wire specification stands for Moisture and Heat Resistant-Cross-Linked Thermosetting. This indicates that the wire is designed to withstand high temperatures and resist moisture. The term "cross-linked" suggests that the wire has been treated or processed to enhance its durability and resistance to heat and moisture. The term "thermosetting" implies that the wire has been molded or formed into a specific shape or configuration that will not change when exposed to heat. Overall, XHHN wire is suitable for applications where high temperature and moisture resistance are required.
