Key Performance & Design Advantages
-
Extreme Thermal Ceiling (200ºC): Specifically designed to withstand continuous exposure to high temperatures without melting, cracking, or losing electrical integrity, making it far superior to standard PVC or XLPE wires.
-
Comprehensive Size Range (30AWG – 600kcmil): From precision 30 AWG electronics leads to massive 600 kcmil power distribution cables, the UL3965 series meets the needs of both micro-electronics and heavy industrial power systems.
-
Certified Oil Resistance: Optimized for the internal wiring of appliances where the wire may be exposed to oil. The SR insulation is chemically formulated to resist degradation in oily environments (within rated temperature limits).
-
Streamlined Assembly: Features uniform insulation thickness across the entire length. This precision ensures consistent dielectric strength and enables easy stripping and cutting, significantly increasing efficiency in high-speed automated production lines.
-
Superior Flexibility: The Silicone Rubber (SR) jacket provides a high degree of flexibility and a tight bend radius, allowing for easy installation in cramped housings or complex wiring looms.
-
Safety & Regulatory Compliance: Built according to UL758 and UL1581 standards. It passes the FT2 Horizontal Flame Test for enhanced fire safety and is fully RoHS compliant for environmental sustainability.
Ideal Applications
The UL3965 wire is the trusted choice for:
-
Professional Kitchen Equipment: Internal wiring for high-end commercial ovens, fryers, and industrial grills.
-
Heavy Industrial Machinery: Motor leads, transformers, and power generators where oil and heat are constant factors.
-
Lighting Systems: High-wattage HID lamps, stage lighting, and industrial lighting fixtures.
-
Heating Elements: Reliable connections for HVAC units and industrial drying equipment.
