UL3321 wire is an American standard electronic wire with a rated temperature of 150℃ and a rated voltage of 600V. The conductor is made of single or stranded tin plated or bare copper wire, and the insulation is made of cross-linked flame-retardant polyolefin material. It has excellent mechanical and electrical performance, complies with RoHS standards, and is widely used in internal connection lines of electronic and electrical equipment, such as motors, transformers, lighting fixtures, and other devices.

Application

UL3321 wires have excellent performance and are therefore widely used. In the field of electronic appliances, internal connection wires commonly used in motors, transformers, lighting fixtures, ballasts and other equipment can work stably in a high temperature environment of 150℃, ensuring the normal operation of the equipment. In the construction industry, large public buildings such as train stations, airports, shopping centers, and other crowded places will use this cable. Its low smoke and halogen-free characteristics can reduce smoke and harmful gases in case of fire, ensuring personnel safety. In terms of rail transit, UL3321 wires are often used in transportation vehicles with high safety requirements such as subways and light rails to meet their strict requirements for fire prevention and low smoke performance. In industrial production, industries with high environmental requirements such as chemical and metallurgical industries are widely used in internal wiring of electrical circuits, instrument lines, distribution systems, and measurement systems due to their excellent corrosion resistance and fire resistance.
