25kV High-Temperature Igniter Wire with Fiberglass Jacket
TEBAOFLEX high-temperature igniter wire serves ignition circuits that operate near burners, flare systems and process equipment. The listed single-core construction combines nickel-plated copper conductors, multilayer mica tape, a PTFE moisture barrier and a fluoropolymer-coated fibreglass jacket.
Consequently, the wire supports high-voltage connections in applications that require heat resistance and installation flexibility. Before ordering, confirm the ignition voltage, ambient temperature, routing and required cable length with TEBAOFLEX.
Key Construction Features
- Nickel-plated copper conductor: The conductor supports high-temperature service and maintains flexibility through fine stranding.
- Multilayer mica tape: Mica tape adds a heat-resistant insulation layer and supports long-term durability.
- PTFE moisture barrier: The moisture barrier forms part of the listed multilayer insulation construction.
- Fibreglass braid jacket: The braid provides a mechanical layer that resists abrasion and high-temperature exposure.
- Fluoropolymer coating: The coating protects the fibreglass braid and assists installation in weathered or chemical-exposure environments.
In addition, the wire uses a layered construction to combine thermal performance with a flexible installation profile.
