Key Performance & Design Advantages
-
Ultra-High Heat Endurance (200°C): Engineered for the most demanding thermal conditions, the UL3788 maintains its mechanical flexibility and dielectric strength at constant temperatures up to 200°C.
-
1000V AC High-Voltage Protection: Designed to handle significant electrical loads, providing a robust insulation barrier for high-power appliance circuitry and industrial machinery.
-
Extensive Gauge Versatility: We offer a full range of sizes from precision 30 AWG for delicate controls to massive 1000 kcmil for heavy-duty power distribution.
-
Superior Oil Resistance: Specifically designed for internal wiring in appliances where the wire may be exposed to oil. The SR insulation prevents swelling and degradation, ensuring long-term reliability in oily environments.
-
Optimized for Assembly: Our manufacturing ensures a uniform insulation thickness, which guarantees consistent performance and allows for easy stripping and cutting—ideal for high-speed automated production.
-
Safety & Eco-Certification: Fully compliant with UL758 and UL1581 standards. It has successfully passed the FT2 Horizontal Flame Test and meets all RoHS environmental requirements.
Ideal Applications
The UL3788 wire is the industry standard for:
-
Industrial Appliances: Internal wiring for commercial ovens, industrial heaters, and high-temperature dryers.
-
Heavy Power Systems: Motor leads, transformers, and power generators requiring 200°C resilience.
-
Lighting Technology: High-wattage industrial lighting and stage equipment.
-
Harsh Environments: Equipment and machinery frequently exposed to high heat and industrial lubricants/oils.
