FEP Sheathed Cable 3×1.5mm2 UL: Reliable High-Temp Wiring for Industrial Ovens
Wire insulation inside an industrial oven doesn’t just age—it fractures, outgasses, and becomes a fire hazard. These slow, heat-driven failures eat into production margins and trigger unplanned downtime. The FEP sheathed cable 3×1.5mm² is built specifically to stop that cycle. Its fluoropolymer jacket handles sustained high temperatures with zero embrittlement, while the UL listing gives your QA team a direct path through equipment audits. No exotic materials. Just a predictable, documented thermal lifespan that shifts oven wiring from emergency maintenance to scheduled replacement.
FEP Jacket with Zero-Tolerance for Thermal Drift
Feature: Extruded FEP sheath rated for continuous exposure inside factory ovens and heating enclosures.
Advantage: The jacket’s molecular structure resists thermal oxidation and mechanical cracking, even when cabling runs within 20 mm of radiant elements. Dielectric strength stays flat across the cable’s full service life.
Benefit: Maintenance cadence becomes date-driven, not failure-driven. Bakeries, heat-treatment shops, and plastics processors eliminate the 3:00 a.m. call-out for a tripped oven breaker caused by shorted conductors.
UL Listing That Passes Audit, Not Just a Sticker
Feature: Fully listed under the applicable UL standard (file documentation supplied with every shipment).
Advantage: Your factory’s third-party safety auditor sees a recognized NRTL mark—no supporting evidence needed for the internal wiring of baking, curing, or drying ovens. The listing also covers conductor size and temperature class without your team having to correlate multiple standards.
Benefit: Equipment sign-off and re-certification move faster. Cross-border shipments of pre-wired oven skids clear local AHJ inspection with fewer hold-ups. One less set of compliance letters to write.
3-Core 1.5mm² Configuration Built for Control and Auxiliary Circuits
Feature: Three discrete tinned-copper conductors, each 1.5 mm², laid up under the FEP sheath.
Advantage: The cross-section handles low-power motor loads, contactor signals, and RTD/probe circuits inside a single, slim-profile cable. No need to run multiple singles inside a hot, cramped conduit space.
Benefit: Panel builders trim an hour per oven from wiring and looming time. Field technicians trace a single cable instead of a spaghetti bundle when replacing a burner control valve or a circulating fan relay. Faster rewiring equals shorter commissioning.

Industry Applications & Scenario Validation
- Commercial bakery tunnel ovens. Continuous convection heat up to 260 °C degrades standard PVC insulation inside months. FEP sheathing keeps control wiring intact regardless of fat-laden vapour and hourly thermal cycling.
- Laboratory drying and sterilisation ovens. Cross-contamination from outgassed insulation skews life-science and material-testing results. This cable’s low-offgassing FEP jacket preserves environmental chamber integrity.
- Plastics curing and preheating drums. Plasticizer vapours attack many cable jackets. FEP is chemically inert—it won’t swell, soften, or lose voltage rating when exposed to styrene or acrylic fumes.
- Heat-treatment furnace control-box leads. Conduit entry points trap radiant heat. This 3×1.5mm² cable brings thermocouple extension and contactor coil wires into the junction box without derating due to accumulated ambient heat.
- Powder-coating and paint-cure line ovens. Overspray particulate settles on cable trays. The non-stick FEP surface resists coating build-up and wipes clean during preventive maintenance, saving the shift electrician an hour of scraping per monthly PM cycle.

FAQ
What continuous temperature can this 3×1.5mm² FEP cable withstand inside an industrial oven?
FEP generally maintains electrical and mechanical properties up to 200 °C, but the certified limit depends on the specific UL listing applied to this construction. Check the temperature class printed on the cable and match it to your oven’s worst-case wiring tray temperature. For intermittent peaks near heating elements, request a thermal derating chart from our applications team—it maps expected life against steady-state and spike temperatures.
Can the 3-core 1.5mm² cable be used for both motor power and sensor signals inside the same oven?
Yes, as long as the current draw does not exceed the conductor ampacity defined by the relevant UL table for your ambient temperature. Many OEMs designate one core for a circulating fan relay, one for a flame-safety sensor loop, and one spare. Using a single cable simplifies the conduit fill and reduces the number of high-temperature penetrations through the oven wall. Always confirm the voltage class on the cable datasheet before tying sensor and power circuits together under a common jacket.
Do you supply this cable cut-to-length or as pre-assembled oven looms?
We stock standard 100 m reels for immediate dispatch. For volume programs, we supply factory-cut lengths at ±0.5% tolerance, tinned and labelled per your BOM. Pre-assembled looms with high-temperature silicone fibre over-braid, crimp terminals, and protective sleeving are available through our value-added assembly service. Lead time for custom-cut cable is typically three working days; assembled harnesses ship in seven to twelve working days, depending on complexity and testing protocol.
