14 AWG UL 3173 Hook-Up Wire | 125°C 600V XLPE Tinned Copper

This 14 AWG UL 3173 hook-up wire is a high-performance internal wiring solution built for reliability in demanding thermal and mechanical environments. By utilizing chemically cross-linked polyethylene (XLPE) insulation, this wire provides a rugged, "thermoset" jacket that maintains its integrity under high heat, resisting the melting and flowing common with standard thermoplastic wires.

Why Choose 14 AWG UL 3173 Hook-Up Wire?

UL 3173 is the industry standard for lead wire in motors, transformers, and electrical appliances where durability is non-negotiable. The 14-gauge conductor offers a versatile mid-range ampacity, making it a "workhorse" for power leads and heavy control circuits. Because XLPE insulation does not shrink back or deform when exposed to soldering heat, it ensures safer, cleaner terminations during the manufacturing process.

• Advanced XLPE Insulation: The chemically cross-linked polyethylene insulation offers superior dielectric strength and will not soften at high temperatures.

• 125C Thermal Endurance: Rated for continuous operation in environments up to 125C (257F).

• Tinned Copper Conductor: Annealed tinned copper strands provide high conductivity and exceptional resistance to corrosion, particularly at terminal connections.

• Exceptional Toughness: Highly resistant to abrasion, cut-through, and mechanical impact, ensuring the wire stands up to vibration in industrial settings.

• Chemical & Moisture Resistance: The XLPE jacket is impervious to most industrial oils, acids, alkalis, and moisture ingress.

• Triple Certification: Complies with UL Style 3173, UL Style 3195, and CSA Type CL1251.
