Applications
UL3321 wire is designed for internal wiring in electrical and electronic equipment where high-temperature performance, mechanical strength, and a 600V rating are required. It is commonly used in:

Motors and compressors – internal lead wiring for fan motors, pumps, and industrial motors
Home appliances – refrigerators, air conditioners, microwave ovens, ovens, washing machines, and other high-temperature sections
Power and electrical equipment – transformers, power supplies, adapters, battery chargers, and UPS systems
Industrial control systems – control panels, automation equipment, and instrumentation wiring
New energy equipment (auxiliary circuits) – BMS wiring, EV charger internal wiring, and solar inverter internal circuits

This wire is ideal for environments requiring reliable performance under elevated temperatures and enhanced resistance to heat, oil, and chemicals.
