UL 3266 XLPE Insulated Hook-up Wire (125°C / 300V)

High-Density Thermal Protection for Precision Electronic Wiring

CableApex’s UL 3266 wire utilizes advanced XLPE (Cross-linked Polyethylene) technology, offering a perfect balance between high thermal stability and a compact form factor. Rated for 125°C and 300V, this wire is specifically designed for environments that demand superior resistance to abrasion and deformation without the bulk of higher voltage cables. Built with 99.99% high-purity oxygen-free tinned copper, UL 3266 ensures long-term conductivity and reliable performance in high-density electrical assemblies.
