UL 3573 Dual-Layer Ignition Wire | 10KV | Vietnam & Indonesia

UL 3573 10000V Dual-Layer Silicone Ignition Wire for Vietnam and Indonesia

UL 3573 is a dual-layer silicone rubber insulated wire with a fiberglass braid or serve between the two insulation layers, rated 200°C and 10000V AC under UL AWM Style 3573, produced under UL Follow-Up Service File No. E333030. UL 3573 covers a conductor range from 22 AWG to 12 AWG in solid or stranded round construction. The construction consists of three concentric layers over the conductor: an inner silicone rubber insulation layer of 30 mils minimum average thickness (27 mils minimum at any point), a fiberglass braid or serve covering over the inner insulation, and a final outer silicone rubber layer of 10 mils minimum at any point over the fiberglass braid. This three-layer construction — inner SR insulation, fiberglass braid, outer SR jacket — is the defining structural feature that distinguishes UL 3573 from UL 3304, and the reason UL 3573 is specified in applications where greater mechanical protection at the wire surface is required beyond what UL 3304’s exposed fiberglass braid outer surface provides.

The outer silicone rubber layer of UL 3573 encapsulates the fiberglass braid, replacing the exposed glass fibre surface of UL 3304 with a smooth, continuous silicone rubber outer surface. This outer SR layer provides cut resistance that the exposed fiberglass braid of UL 3304 cannot provide — a sharp edge or hard contact point at the wire routing location will cut or abrade the glass fibre filaments of an exposed braid over repeated contact cycles, but will compress against the resilient silicone rubber outer layer of UL 3573 without cutting through it. The smooth outer silicone rubber surface of UL 3573 also facilitates routing through tight passages in the appliance structure without snagging on edges — an advantage in gas appliance assembly where the ignition lead must be routed through narrow passages between burner components and the appliance frame during assembly and servicing.

Vietnamese and Indonesian gas appliance OEMs and commercial burner system manufacturers requiring the dual-layer construction describe UL 3573 as dây đánh lửa silicone hai lớp 10000V (dual-layer 10000V silicone ignition wire) in Vietnam and as kabel ignition silikon dual layer 10000V in Indonesia. CableApex exports UL 3573 factory-direct CIF Ho Chi Minh City and CIF Surabaya from Yangzhou.

Applications in Vietnam and Indonesia

Gas range ignition wire with abrasion-risk routing (Vietnam — appliance OEMs)

Vietnamese gas appliance OEMs in Bình Dương, Đồng Nai, and Ho Chi Minh City assembling gas cooking ranges and gas hobs for export to international markets under UL listing specify UL 3573 for the ignition lead routing in appliance designs where the ignition wire must pass through tight passages between burner components and the appliance frame — routing locations where the repeated contact between the wire surface and the appliance frame edges during assembly, servicing, and normal appliance use would abrade the exposed fiberglass braid surface of UL 3304 over the appliance service life. The smooth outer silicone rubber surface of UL 3573 allows the ignition lead to be routed through these tight appliance passages without snagging on burner component edges during assembly, and the outer SR layer resists the surface abrasion at sustained routing contact points over the appliance service life in a way that the exposed braid of UL 3304 cannot.

Vietnamese gas appliance exporters sourcing UL 3573 as dây đánh lửa silicone hai lớp 10000V for their export-grade gas appliance assemblies procure factory-direct from CableApex in Yangzhou — the UL AWM Style 3573 recognition under File No. E333030 satisfying the UL component recognition requirement for gas appliances submitted for UL listing for export to North American and European markets.

Commercial gas burner ignition lead (Vietnam — nhà sản xuất)

Vietnamese commercial gas burner system manufacturers assembling commercial kitchen burner controllers, industrial gas burner management systems, and commercial catering equipment ignition systems for domestic sale and for export specify UL 3573 for the ignition lead from the high-voltage ignition module to the spark electrode in commercial burner assemblies where the ignition lead routing is exposed to more aggressive mechanical contact than in a domestic gas range enclosure. Commercial gas burner assemblies — where the ignition lead is routed externally or semi-externally between the ignition controller and the burner head — expose the ignition wire to contact with burner housing edges, mounting bracket edges, and routing clip contact points that would abrade an exposed fiberglass braid surface over the commercial equipment’s heavy-use service cycle. UL 3573’s outer silicone rubber layer provides the mechanical durability required for this more aggressive routing environment, making it the preferred ignition wire specification for Vietnamese commercial gas equipment manufacturers.

Fuel oil burner ignition lead — Indonesia (kabel ignition dual layer)

Indonesian fuel oil burner system manufacturers and commercial heating equipment assemblers in Bekasi, Surabaya, and Batam assembling industrial fuel oil burners, commercial boiler ignition systems, and industrial furnace ignition systems source UL 3573 as kabel ignition silikon dual layer 10000V for ignition lead applications where the dual-layer construction’s mechanical robustness is required. Indonesian industrial fuel oil burner installations — where the ignition lead is routed through the burner assembly structure and exposed to sustained contact with metal burner components at elevated temperatures — benefit from UL 3573’s outer silicone rubber layer providing sustained abrasion resistance at the routing contact points over the industrial burner’s continuous heavy-duty operating cycle. Indonesian industrial procurement sourcing UL 3573 factory-direct from CableApex in Yangzhou eliminates the distributor markup applied to specialty high-voltage silicone ignition wire through Indonesian electrical equipment distribution channels.

Gas water heater and boiler ignition systems (Vietnam and Indonesia)

Vietnamese and Indonesian gas water heater and commercial boiler manufacturers assembling products for export specify UL 3573 for the ignition lead in gas water heater and boiler ignition systems where the ignition wire routing from the ignition module to the burner electrode passes through the appliance water jacket and burner assembly structure — a routing environment where the ignition wire is exposed to sustained contact with metal appliance structure components at elevated temperatures, and where water condensation on the ignition wire surface creates an additional requirement for a smooth, water-resistant outer surface that the outer silicone rubber layer of UL 3573 provides more effectively than the exposed fiberglass braid of UL 3304.

Additional applications across Vietnam and Indonesia

• Industrial gas furnace ignition systems with external routing — Vietnamese and Indonesian industrial furnace manufacturers where the ignition lead is routed externally between the ignition transformer and the burner electrode with exposure to mechanical contact
• LPG commercial catering equipment — Vietnamese and Indonesian commercial catering equipment manufacturers requiring dual-layer ignition wire for export-grade gas appliance assemblies
• Marine gas appliance ignition systems — Vietnamese and Indonesian shipbuilding and marine equipment manufacturers where the smooth outer SR surface of UL 3573 provides moisture resistance at the ignition wire routing location in marine enclosures
• Replacement ignition wire for imported equipment — Vietnamese and Indonesian maintenance operations replacing original dual-layer silicone ignition wire in imported European and Japanese gas appliance equipment where the dual-layer construction must be matched
