Key Performance & Design Advantages
-
Extra-High Voltage Capability: Rated for 6000V DC, the UL3782 is specifically designed to manage high-potential circuits, providing a superior dielectric barrier that prevents leakage and electrical arcing.
-
Extreme Temperature Resilience: With a 200°C rating, this wire maintains its mechanical and electrical integrity in environments where standard insulation would melt or become brittle.
-
Designed for Enclosed Wiring: This wire is optimized for internal wiring in applications where it is totally enclosed, making it perfect for static installations not subjected to constant movement or mechanical abuse.
-
Precision Processing: Our uniform insulation thickness ensures consistent protection along the entire length of the cable, facilitating easy stripping and cutting for high-efficiency automated assembly.
-
Rugged Silicone Insulation: The SR (Silicone Rubber) jacket offers excellent chemical resistance and flexibility, ensuring a long service life in demanding industrial conditions.
-
Safety & Regulatory Compliance: Meets UL Subject 758 and UL1581 standards and has passed the FT2 Horizontal Flame Test, ensuring your products meet global safety requirements and RoHS environmental standards.
