Product Description
The UL Style 3321 Electronic Wire is a high-performance cable designed for precision electronic applications that demand reliability, flexibility, and compliance with strict safety standards. This wire features a tinned copper conductor, either solid or stranded, encased in a thin yet durable fluoropolymer insulation, such as FEP or PTFE, which offers exceptional chemical and temperature resistance. The insulation is engineered to have a low dielectric constant, minimizing signal loss and interference, making it ideal for high-frequency applications.
Rated for voltages up to 600V and operating temperatures ranging from -65°C to +200°C, the UL 3321 wire can withstand extreme environmental conditions, including exposure to solvents, oils, and UV radiation. The compact design with a thin insulation wall allows for maximum conductor space in tight installations, while the smooth surface reduces friction during routing. It is available in a wide range of AWG sizes (from 30 AWG to 16 AWG) and is commonly used in applications that require both electrical performance and mechanical durability.
Features
Wide Temperature Range: Capable of operating efficiently in sub-zero cold and high heat, making it suitable for aerospace, industrial, and automotive electronics.
Low Signal Loss: The fluoropolymer insulation has excellent dielectric properties, ensuring minimal attenuation in high-frequency signal transmission, critical for data and communication systems.
Chemical Resistance: Resistant to most solvents, fuels, and corrosive substances, making it ideal for harsh industrial environments.
UL Certified: Meets Underwriters Laboratories (UL) standards for safety, including flammability (VW-1 rating) and environmental stress cracking, ensuring compliance with North American electrical codes.
Space-Saving Design: The thin insulation wall allows for dense wiring in confined spaces without compromising on performance or safety.
Application
The UL Style 3321 Electronic Wire is widely used in sophisticated electronic and industrial systems, including:
Aerospace and Aviation: Used in avionics, navigation systems, and engine sensors, where extreme temperature and vibration resistance are essential.
Industrial Controls: Connecting programmable logic controllers (PLCs), sensors, and automation equipment in manufacturing plants, often exposed to oils, chemicals, and high temperatures.
Medical Devices: Suitable for internal wiring in medical equipment, where biocompatibility and resistance to sterilization processes (e.g., autoclaving) may be required.
High-Frequency Equipment: Used in radio transmitters, antennas, and data cables for telecommunications, where low signal loss is critical.
Automotive Electronics: Ideal for advanced driver-assistance systems (ADAS), infotainment systems, and sensor wiring in modern vehicles, which require reliable performance in fluctuating temperatures.
Faq
Q: What is the difference between FEP and PTFE insulation in UL 3321 wire?
A: FEP (fluorinated ethylene propylene) is more flexible and easier to strip, while PTFE (polytetrafluoroethylene) offers slightly higher temperature resistance (up to 260°C) but is stiffer. Both meet UL standards.
Q: Can this wire be used for direct burial?
A: While it has excellent chemical resistance, direct burial is not recommended without additional protective conduit, as the insulation is not designed for prolonged soil contact or mechanical stress from backfill.
Q: Does it support high-speed data transmission?
A: Yes, the low dielectric constant of the fluoropolymer insulation makes it suitable for high-speed data cables, including Ethernet and USB 3.0 applications.
Q: What is the flame rating of this wire?
A: It meets the VW-1 vertical flame test standard, which means it self-extinguishes within 60 seconds after the removal of the flame source.
Q: Can I use a standard wire stripper for the thin insulation?
A: It is recommended to use a precision stripper or a hot knife to avoid damaging the conductor, as the thin insulation requires careful handling.
