Choosing high-temperature wires
Four things decide most selections. Our engineers check the rest against your application.
Application and movement duty
- Define whether the cable runs in a fixed tray, energy chain, festoon loop, reel or trailing route.
- Match travel speed, bend radius and tensile load to the mechanical construction.
- Select a support element or armour when the cable carries suspended weight or external crush loads.
Voltage class and core layout
- Match the rated voltage U0/U to the supply system and earthing arrangement.
- Specify phase cross-sections, protective earth, pilot cores or control pairs required by the machine.
- Include copper braid, tape or semiconductive screens where EMC or electric-field control is needed.
Operating environment and sheath
- Choose rubber, PUR, LSZH, PVC, fluoropolymer or silicone sheaths for the thermal and chemical exposure.
- Verify oil, UV, water immersion, cold-flex or circuit-integrity ratings against site conditions.
- Check outer diameter and gland compatibility at both terminations.
Standard and documentation
- Confirm the governing standard family required by the project specification.
- Verify conductor class, colour code or core numbering for the destination region.
- Include operating duty and cable length in your enquiry so we can confirm the build.

Ask on WhatsAppHow do I select the right high-temperature wire from this range?
Start by filtering the list by movement duty, voltage band and sheath material. Compare how each high-temperature wire is constructed—conductor flexibility, insulation compound, screening and outer jacket—against your machine's bending radius, travel speed and ambient temperature. Open the product page or datasheet to check core counts, cross-sections and outer diameters before sending your enquiry.
When should high-temperature wires include metallic screening or armour?
Specify a copper braid or foil screen when high-temperature wires run near variable-frequency drives, carry analogue or fieldbus signals, or require medium-voltage electric-field control. Choose steel wire braid or armour when the installation faces rock fall, crushing loads or high pulling tension in roadways, decks or subsea routes.
Which outer sheath compound suits harsh industrial environments?
Heavy-duty rubber (PCP or CPE) provides balanced mechanical toughness, weather resistance and thermal stability. Polyurethane (PUR) resists cuts, abrasion and mineral oils on fast-moving chains, reels and trolleys. Halogen-free LSZH compounds reduce smoke and acid gas in tunnels, ships and enclosed buildings, while fluoropolymers and silicone handle extreme heat.
What details should I include in an RFQ for high-temperature wires?
Include the model designation or governing standard, rated voltage, number of cores and conductor cross-sections, along with the installation method, minimum bend radius, ambient temperature range and required delivery lengths. If you are replacing an existing cable on a machine, share the sheath marking so we can match the specification.

TEBAOFLEX manufactures high temperature wire for industrial equipment, electrical appliances, heating systems, motors, generators and other applications where conventional wire insulation may not provide sufficient thermal resistance. Our high temperature wire range includes PTFE, FEP, PFA, ETFE, silicone rubber, fiberglass and mica insulated constructions for different operating temperatures, voltage levels, flexibility requirements and installation conditions.
The product range includes high temperature hook-up wire, equipment wire, fixture wire, aerospace wire and motor lead wire for OEM and industrial applications. Fluoropolymer insulated wires such as PTFE, FEP, PFA and ETFE are available for applications requiring compact dimensions, thermal resistance and demanding electrical performance, while silicone rubber constructions provide flexibility for machinery, heating equipment, appliances, motors and other high-temperature environments. Fiberglass and mica based constructions are also available for applications exposed to more severe thermal conditions.
Selecting the appropriate high temp wire depends on more than temperature alone. Rated voltage, conductor size, insulation material, flexibility, installation method, mechanical requirements and applicable standards should all be considered when specifying a wire construction.
If you already have a cable model, drawing or technical specification, send it to TEBAOFLEX for review and quotation. If the exact construction has not yet been determined, provide the operating temperature, voltage, conductor size, application and quantity, and our team can help identify a suitable high temperature wire for your project.
