View MoreProduct OverviewThe 125 °C cross-linked polyolefin insulated electronic wire (commonly referred to as XLPO electronic wire) is a high-performance internal connection wire specifically designed for electronic and electrical equipment requiring high temperature resistance, with limited space and needing long-term stable operation. This product undergoes a cross-linking process that transforms the polyolefin molecular structure from linear to a three-dimensional network, thereby raising its continuous operating temperature to 125 °C. With its sound electrical insulation properties, chemical corrosion resistance, and ageing resistance, and because it does not produce large amounts of toxic smoke during combustion (an environmentally friendly characteristic), this series of electronic wires is widely used in new energy, industrial automation, and internal wiring of high-end household appliances.
Executive Standards
This product is manufactured and tested in strict accordance with internationally recognized safety standards for electronic wires:
- UL 758-2022: Standard for Appliance Wiring Material (AWM).
- Complies with RoHS/REACH environmental directives.
Common Models and Voltage Ratings
Depending on different application requirements, the product covers multiple models ranging from low voltage signal to high voltage power:
- UL 3266: Rated voltage 300 V, a thin-wall high-temperature type.
- UL 3271 / UL 3173 / UL 3290: Rated voltage 600 V, general-purpose high-temperature electronic wire.
- UL 3817: Rated voltage 3000 V, high voltage, heat-resistant 125 °C flame retardant electronic wire.
Product Specification Range
The conductor uses high-quality annealed copper wire or tinned copper wire, covering a wide range of specifications for both micro-current and high-power transmission:
- 300 V specification (UL 3266): Single-core, 22 AWG – 14 AWG.
- 600 V specification (UL 3271, etc.): Single-core, 22 AWG – 4/0 AWG.
- 3000 V specification (UL 3817): Single-core, 22 AWG – 4/0 AWG (or 1×22 AWG – 1×6 AWG).
Core Technical Parameters
1. Rated temperature: 125 °C.
2. Rated voltage: 300 V / 600 V / 3000 V.
3. Insulation performance: Very high volume resistivity, maintaining sound dielectric strength even in high-humidity or high-temperature environments.
4. Flame retardant performance: Passes the UL VW-1 and FT1 vertical flame tests, offering strong self-extinguishing properties.
5. Mechanical characteristics: The cross-linking process significantly enhances the cut-through resistance and abrasion resistance of the insulation layer, facilitating routing within complex equipment enclosures.
Cable Structural Characteristics
- Conductor: Uses Class 5 flexible conductor (stranded fine copper wires), available in bare copper or tinned copper. The tinned conductor effectively prevents copper wire oxidation, improving solderability and corrosion resistance.
- Insulation layer: 125 °C cross-linked polyolefin (XLPO) environmentally friendly material. The insulation wall thickness is uniform, the surface is smooth, and it strips easily, making it suitable for automated wire stripping and crimping production.
- Environmental friendliness: The material is free of halogens, lead, cadmium, and other hazardous heavy metals. It produces very low smoke during combustion, meeting green environmental and life safety requirements.
Applicable Scenarios
- New energy vehicles: Used for in-vehicle battery management system (BMS) connections, internal wiring of charging piles, and high-voltage control box wiring.
- Motors and transformers: Used as lead wires for high-temperature motors or outgoing wires for transformer windings.
- Industrial control: Signal and power transmission within electrical control cabinets, variable frequency drives, and automation equipment.
- Household appliances: Internal connections of high-heat-generating appliances such as microwave ovens, dishwashers, and lighting fixtures.
Performance Advantages Summary
1. Strong temperature resistance: The 125 °C temperature rating provides a longer service life than standard PVC wire (rated below 105 °C) under harsh thermal cycling conditions.
2. Chemical corrosion resistance: The insulation material offers good resistance to grease, acids, alkalis, and various chemical solvents.
3. High processing efficiency: XLPO material does not shrink or melt at the insulation during soldering, ensuring the assembly quality of connection terminals.
4. Large safety margin: The 3000 V high-voltage type in particular provides a high level of safety redundancy for energy storage and high-voltage power electronic equipment.
