What is the primary application for UL 3304 wire?

According to the official UL 3304 standard, this wire is specifically designed for the internal wiring of electronic ignition systems, such as those in gas ranges, gas burner systems, and fuel oil burner systems.

What are the temperature and voltage ratings of UL 3304?

UL 3304 ignition wire is rated for extremely high voltage up to 10,000 Vac (10KV) and can withstand a continuous maximum temperature of 200°C. It also meets the horizontal flame test requirements.

What is the insulation construction of UL 3304?

It features a robust 40-mil extruded silicone rubber (SR) insulation, which provides superior dielectric strength. The core is protected by an outer layer of durable fiberglass braid.

UL 3304 High Voltage Ignition Wire

Premium UL 3304 High-Voltage Ignition Wire (10KV, 200°C)

Engineered for secure and reliable electronic ignition, the UL 3304 wire is a heavy-duty high-voltage cable designed specifically for gas ranges, fuel oil burner systems, and high-heat ignition circuits. Rated for 10,000 Vac, it provides unmatched dielectric strength for extreme electrical environments.

Advanced 40-Mil Silicone Construction

What sets the UL 3304 apart is its robust dual-layer protection system. The primary insulation features extruded SR-Silicone with a minimum average thickness of 40 mils, ensuring exceptional resistance to high-voltage arcing. This extra-thick silicone core is mechanically protected by a durable fiberglass braid, preventing physical abrasion during handling, installation, and appliance servicing.
