UL3271 UL AWM Tinned Copper PV Wire

Product Overview: UL AWM 3271 125℃ 600V XLPE Halogen Free Hookup Wire

Engineered for demanding electrical environments, the UL3271 photovoltaic (PV) wire represents a superior standard in internal wiring solutions. Designed with precision, this hookup wire features a highly conductive copper core protected by a robust, halogen-free cross-linked polyethylene (XLPE) jacket. When handling this wire, engineering teams will immediately notice the smooth, uniform texture of the insulation, which is specifically formulated to resist harsh environmental factors while maintaining excellent flexibility. Whether integrated into a complex solar energy grid, a high-capacity energy storage unit, or a compact motor assembly, it delivers consistent power transmission without compromising safety. The advanced construction ensures that the wire remains pliable yet highly durable, resisting cracking or degradation even after prolonged exposure to elevated operational temperatures.

• Rated Voltage: 600V. Designed to handle substantial electrical loads, this 600-volt rating ensures stable and secure power delivery across various demanding applications, minimizing the risk of electrical faults or voltage drops in high-capacity circuits.

• Rated Temperature: 125ºC. The advanced XLPE insulation provides exceptional thermal stability. It maintains its structural integrity and insulating properties even when subjected to continuous operating temperatures up to 125 degrees Celsius, preventing melting in heat-intensive compartments.

• Insulation Material: Premium Halogen-Free XLPE. Utilizing cross-linked polyethylene, the outer jacket offers outstanding defense against abrasion, chemicals, and moisture. Being completely halogen-free, it guarantees that in the rare event of extreme heat or combustion, it will not release toxic or corrosive gases, thereby protecting sensitive electronic components and ensuring operational safety.

• Conductor: Tinned or Bare, Stranded or Solid Copper. Sourced from high-purity copper, the core delivers optimal electrical conductivity. The optional tinned coating provides an extra layer of defense against oxidation and corrosion, ensuring long-lasting performance in humid atmospheric conditions. The stranded configuration also offers enhanced physical flexibility for intricate routing in tight spaces.

• Reference Standard: UL758, UL1581, C22.2 No.210. Strictly adhering to international compliance frameworks, this wire passes rigorous safety and performance evaluations. By fully meeting RoHS and REACH environmental directives, it ensures that your final assembled equipment faces no regulatory barriers when exported to global markets.

• Uniform insulation thickness of wire to ensure easy stripping and cutting. Manufactured with ultra-low eccentricity, the precise concentricity of the insulation layer is specifically engineered for modern automated wire harness processing equipment. This precise geometry allows mechanical stripping blades to remove the jacket cleanly without nicking the delicate copper strands, drastically reducing material waste and boosting assembly line throughput.

• Core Application Scenarios: Highly versatile and reliable, this wire is the preferred choice for the internal wiring of sophisticated electronic and electrical equipment. It is extensively utilized in photovoltaic (PV) inverters, new energy storage systems, industrial motors, engine compartments, and high-density power modules where space is limited but performance requirements are absolutely critical.
