UL 3302 Crosslinked XLPE Wire

1. Product Overview

UL 3302 Crosslinked XLPE Wire is a specialized internal wiring solution designed for Class 2 circuits in electronic equipment. It features a crosslinked polyethylene (XLPE) insulation layer and a conductor made of bare or tinned copper, delivering excellent heat resistance and flame retardancy. Compliant with international safety certification standards, it ensures stable signal and power transmission in low-voltage circuits of precision electronic devices.

2. Core Performance Parameters

· Rated Temperature: 105℃ – maintains stable performance in continuous high-temperature environments without degradation of insulation properties.

· Rated Voltage: 30V – suitable for power supply and signal transmission in Class 2 low-voltage circuits inside electronic equipment.

· Flammability Rating: Passes UL VW-1 and CSA FT1 vertical flame tests, providing excellent flame retardancy to slow fire spread.

· Compliance Standards: Meets UL 758, UL 1581, CSA C22.2 No.210.2, IEC60754-2, ensuring reliable safety and quality.

3. Structural Features

     1. Conductor: Constructed from stranded or solid bare/tinned copper, delivering excellent conductivity and oxidation resistance, with flexibility to fit diverse wiring spaces.

     2. Insulation Layer: Made of crosslinked polyethylene (XLPE), which offers better heat resistance, chemical resistance, and mechanical strength than standard PVC insulation, resisting aging and cracking over long-term use.

4. Applications

Widely used in internal Class 2 circuit wiring for consumer electronics, smart wearable devices, and small precision instruments, including:

· Signal transmission between internal sensors and motherboards in smart watches

· Power supply and signal lines for Bluetooth headsets

· Low-voltage control circuits in small medical instruments
