UL 5334 300V 450°C Mica Glass Fiberglass Wire
UL 5334 high-temperature wire is a single-core 300 V wiring solution for equipment that operates in demanding heat zones. Its mica glass composite insulation and fiberglass braid covering help support high-temperature internal wiring where standard thermoplastic wire is not suitable. The product family is available in 24 AWG to 14 AWG constructions for project-specific equipment wiring.
TEBAOFLEX reviews the conductor size, insulation build, braid finish, color and required marking before production. Therefore, customers can align the construction with the equipment temperature, wiring space, termination method and applicable project documentation.
Key Features
- 450°C high-temperature wire construction for specified equipment wiring applications.
- 300 V voltage class for UL 5334-style high-temperature wire requirements.
- Stranded nickel-coated copper conductor construction.
- Mica glass composite insulation with a fiberglass braid outer covering.
- Available from 24 AWG to 14 AWG, subject to the final construction review.
- Natural, solid-color and tracer identification options can be reviewed for production.
Cable Construction
Conductor
The conductor uses stranded nickel-coated copper selected for high-temperature wire construction. The final strand design and conductor material option should be confirmed against the required termination process and electrical load.
Insulation and Outer Covering
A mica glass composite insulating system surrounds the conductor. In addition, a fiberglass braid with a high-temperature finish provides the external covering. This construction is intended for protected internal equipment wiring, rather than unrestricted outdoor, submerged or continuous-motion installation.

Applications and Selection Notes
This 300 V high-temperature wire can be considered for internal connections in industrial ovens, furnaces, heating equipment, thermal-process machinery and high-heat electrical assemblies. It is also suitable for wire routing near controlled heat sources where the specified conductor temperature and installation conditions have been reviewed.
First, define the conductor size and expected electrical load. Next, confirm the maximum conductor temperature, local ambient temperature, routing clearance and termination method. Finally, specify any flame, approval, color, marking or delivery requirements. These conditions determine whether the standard construction or a customized build is appropriate.
Customization
TEBAOFLEX can review conductor stranding, insulation build, braid finish, color, tracer, printing, cut length and spool or reel packing. Please provide the required AWG size, voltage, operating temperature, application, length, quantity and any required compliance documentation.
