UL 3573 10,000V Silicone Rubber Ignition Wire for Riyadh and Saudi Arabia
UL 3573 is a high voltage silicone rubber ignition lead wire rated 200°C and 10,000V AC under UL AWM Style 3573. Like UL 3304, it is used for gas burner and gas appliance ignition circuits — but UL 3573 is the specification for enclosed, protected ignition circuit routing rather than open routing. The key difference from UL 3304 is that UL 3573 incorporates a fiberglass braid or jacketed outer covering as part of the standard construction, providing mechanical protection for ignition leads that are routed through conduit, cable channels, or tight equipment assemblies where the wire could be subject to abrasion, pinching, or contact with hot metal surfaces.
In Riyadh’s industrial and commercial sectors, UL 3573 ignition wire is the specification used by gas appliance OEMs, industrial burner manufacturers, and HVAC equipment builders who design ignition lead routing inside enclosed equipment housings — where the lead is protected from direct flame exposure but must still withstand the elevated ambient temperature inside the appliance and the 10,000V ignition pulse. Saudi Arabia’s large base of gas-fired commercial kitchen equipment, industrial process heaters, and commercial HVAC boiler plant creates consistent procurement demand for both UL 3304 (open routing) and UL 3573 (enclosed routing) ignition wire. CableApex manufactures UL 3573 under File No. E333030 and supplies factory-direct to Riyadh and across Saudi Arabia (CIF Jeddah).

Supply to Riyadh and Saudi Arabia
Riyadh gas appliance OEM procurement
Riyadh hosts a growing base of gas appliance assembly operations and equipment maintenance companies serving Saudi Arabia’s residential and commercial gas appliance market. Gas range manufacturers, commercial oven assemblers, and water heater producers sourcing ignition components for the Saudi domestic market specify UL 3573 for the internal ignition lead routing inside enclosed appliance housings — where the wire runs through metal conduit or cable channels inside the appliance body from the control board ignition transformer to the spark electrode. UL 3573’s fiberglass braid outer protection resists abrasion against the metal edges of the appliance housing during routing and service.
Industrial burner manufacturers — Saudi Arabia export
Saudi Arabia’s industrial burner equipment sector supplies gas-fired process burners to the petrochemical, cement, food processing, and general manufacturing industries across the GCC. Burner management systems use UL 3573 for the ignition lead connections inside the burner control enclosure — where the lead is routed through the control panel wireway from the ignition module to the HV output connector that connects to the external electrode lead. The fiberglass braid covering of UL 3573 provides the mechanical protection and temperature resistance required in this compact, high-temperature control panel environment.
HVAC boiler equipment — Riyadh
Commercial gas boilers and hot water generators installed in Riyadh commercial buildings route their ignition leads inside the boiler casing through metal clips and conduit segments. UL 3573’s covered construction is preferred for these enclosed routing applications over UL 3304 bare silicone wire, providing mechanical protection during installation and service — an important consideration given that boiler ignition leads are frequently accessed by maintenance technicians and must withstand repeated handling without insulation damage.

Common Applications in Saudi Arabia
Gas appliance internal ignition routing (Riyadh OEMs)
Ignition lead wire routed inside gas range, oven, and water heater housings in Riyadh assembly operations — from the ignition transformer output through metal conduit to the spark electrode connector. The fiberglass braid provides abrasion resistance against metal housing edges during production and maintenance.
Industrial process burner control enclosures
Ignition module to HV output connector wiring inside burner management control panels in Saudi Arabia’s industrial process heater and furnace equipment — where the compact, high-temperature panel environment requires covered wire for mechanical protection alongside the 10,000V and 200°C electrical ratings.
Commercial boiler ignition systems (Riyadh)
Enclosed ignition lead routing inside commercial gas boiler casings for Riyadh HVAC plant — where UL 3573’s covered construction survives repeated handling by maintenance technicians without insulation damage, extending the service interval for ignition lead replacement.
Other applications
- Gas turbine pilot burner ignition — enclosed routing variant
- Industrial drying oven burner ignition panel wiring
- Gas-fired infrared heating equipment ignition leads
- Marine gas appliance ignition circuits for Saudi Red Sea and Gulf ports
