1. Application Scope & UL High-Temperature Style Comparison
UL 3513 is the dedicated metric-cross-section (`0.50 mm²` to `240 mm²`) 600 V, 200°C fiberglass-braided silicone rubber style under UL 758 Appliance Wiring Material (AWM), allowing global OEMs of industrial ovens, Class H/C motors, dry-type transformers, extrusion barrel heaters, and commercial kitchen equipment to specify exact IEC metric copper sizes while retaining North American UL AWM compliance.
Primary Protected Hot-Zone Duty
- Industrial Furnaces, Kilns & Extruder Heaters: Internal feeder and heater-band leads from
1.5 mm²up to240 mm²heavy bus jumpers routed near radiant thermal zones. - Class H (180°C) Motors, Generators & Dry Transformers: Stator coil leads and terminal-box jumpers resisting varnish bake cycles without insulation cracking.
- Commercial Baking Ovens, Dryers & High-Bay Luminaires: Flexible silicone core paired with a scuff-resistant E-glass outer sleeve for metal-chassis pass-throughs.

2. 3-Layer Construction & Conductor Finish Engineering
Matching the single-core studio cutaway (`stranded plated copper -> brick-red vulcanized SIR silicone rubber -> white heat-set fiberglass braid printed TEBAOFLEX CABLE`), every layer is selected to maintain dielectric integrity even if extreme thermal overload degrades the organic elastomer into non-conductive silica ash held in place by the glass sleeve.
| Component Layer | Material Options | Thermal & Termination Selection Criteria |
|---|---|---|
| 1a. Conductor (Tinned Cu) | Class 5 flexible stranded annealed tinned copper per IEC 60228 (default standard) | Best all-round choice up to +180°C continuous (with peaks to +200°C); effortless soldering and standard crimp lug compatibility. |
| 1b. Conductor (Nickel-Plated Cu) | 2% or 27% Nickel-plated copper (`NPC`), flexible stranded | Recommended where conductor core runs continuously at +180°C to +200°C or terminates directly onto glowing heater studs via high-temp nickel lugs/spot-welding. |
| 1c. Conductor (Bare Cu) | Unplated annealed copper (Class 5 flexible or Class 1 solid on small sizes) | Available where specified for sealed compression lugs or vacuum-impregnated motor coil connections below +150°C terminal ambient. |
| 2. Primary Insulation (SIR) | Extruded peroxide/platinum-cured Silicone Rubber (SIR), stepped from 30 mil (`0.76 mm`) to 95 mil (`2.41 mm`) | Retains soft elasticity from -60°C to +200°C, zero halogens, corona/ozone resistance, and stable 600 V dielectric strength. |
| 3. Outer Protective Braid | Tightly woven alkali-free E-glass fiberglass saturated with high-temp silicone resin varnish | Reinforces soft silicone against sheet-metal edge cut-through, binds glass fibers to reduce stripping fray, and accepts colour tracers or surface print. |

Installation & Assembly Precautions: Install UL 3513 exclusively as protected internal equipment wiring away from sharp burrs, oil immersion, or continuous drag-chain flexing. Always match crimp ring terminals (for example nickel-plated steel lugs above
+150°C) and fibreglass/silicone end-sleeving to the actual terminal stud temperature.5. Frequently Asked Questions & Custom Production Quote
How does UL 3513 differ from UL 3071, UL 3122, and UL 3512 silicone wires?
UL 3513 is the metric-cross-section (
0.50 mm² up to 240 mm²) 600 V, 200°C fiberglass-braided silicone style under UL 758, ideal for European/IEC motor, furnace, and transformer OEMs needing UL recognition in mm² gauges. UL 3071 is the American AWG-sized (18 AWG to 4/0 AWG) 600 V 200°C braided equivalent; UL 3122 is a lighter 300 V 200°C braided hook-up wire; and UL 3512 is the metric 600 V 200°C plain silicone wire without an outer fiberglass braid.When should I specify nickel-plated copper instead of tinned copper in UL 3513 wire?
Tinned copper offers easy soldering, low contact resistance, and reliable service up to
+180°C continuous (with short peaks to +200°C). When the conductor itself runs continuously at +180°C to +200°C near cartridge heaters, kiln terminals, or Class H/C motor windings, or where high-temperature ring-terminal crimping/welding is used, specify 2% or 27% nickel-plated copper to prevent tin-copper intermetallic growth and surface oxidation.How is fiberglass braid fraying controlled during automatic cut-and-strip harness production?
TEBAOFLEX saturates the outer E-glass braid with a cured high-temperature silicone resin varnish that binds the glass filaments against fluffing while maintaining cabinet routing flexibility. For automated rotary-blade or V-blade stripping lines, inform our team during quotation so varnish cure hardness and silicone-to-conductor release tension can be tuned to your stripping machine.
Can UL 3513 wire be used outdoors, underwater, or in continuous drag chains?
No. UL 3513 is certified under UL 758 as internal Appliance Wiring Material (AWM) for protected enclosures, motor housings, luminaires, ovens, and furnace cabinets. The woven glass braid protects soft silicone rubber against assembly abrasion and hot chassis contact, not pressurized water immersion, outdoor UV/weathering, or multi-million-cycle drag-chain motion.
