Belden Hookup Wire Silicone Series Hook Up Wire, 3.3mm² Cross Sectional Area, White Jacket - 391297 WH005


This hook-up wire is a silicone-insulated conductor designed for high-temperature, high-voltage wiring in industrial and electronic systems. It combines a flexible tin-plated copper core with a silicone rubber jacket to serve demanding installations where thermal resilience and electrical integrity are required.

Features & Benefits


• 65-strand tin copper conductor provides enhanced flexibility for routing
• 150°C maximum operating temperature permits hot-environment use
• 40,000V voltage rating enables high-voltage insulation performance
• VW-1 flame classification reduces flame propagation risk in enclosures
• Silicone jacket maintains pliability from -40°C to 150°C
• UL AWM STYLE 3239 compliance supports recognised appliance wiring standards

**Applications**


• Suitable for high-voltage test leads and laboratory wiring
• Ideal for wire harnesses in automation equipment
• Used with thermal sensors and heating-element connections
• Can be used for internal wiring of power supplies and modules
• Suitable for robotics cabling requiring repeated flexing

What conductor construction gives the wire its flexibility?


It contains a 65-strand tin-plated copper conductor that increases strand count and pliability for repeated bending.

How is the product packaged for continuous installations?


Standard continuous lengths are available on reels of 1000 ft, 500 ft and 100 ft with made-to-order bulk options.

What environmental substance restrictions apply to its manufacture?


Materials conform to RoHS and REACH requirements and meet China RoHS marking standards per SJ/T 11364-2014.

What mechanical limits should be observed during installation?


Minimum bend radius is 10x the cable diameter and maximum pull tension is 51 lb.
