300°C High Temperature Cable – CE Certified, Wholesale Supply for Glass Factories
When the insulation on standard wiring turns brittle and cracks after weeks of exposure to radiant heat near a glass furnace, the result isn’t just a failed cable. It’s a halted production line, a safety audit, and a rushed procurement order you didn’t budget for. Field engineers in glass manufacturing see this pattern repeat every quarter.
The 300°C High Temperature Cable keeps your instrumentation and power connections stable in exactly these zones. Sourced directly through our wholesale channel and backed by full CE documentation, it helps your maintenance team extend service intervals and your supply chain avoid last-minute expediting costs.
Stable 300°C Continuous Rating
- Feature: Insulation system qualified for a continuous conductor temperature of 300°C.
- Advantage: No progressive hardening, dielectric drift, or insulation shrinkage inside the rated thermal envelope.
- Benefit for your factory: You replace thermocouple extension cables and heating element leads on a planned basis — not when a furnace zone trips. Fewer emergency call-outs, less scrap glass, and predictable OPEX.
CE-Labeled, Ready for European Integration
- Feature: Full compliance with the EU Low Voltage Directive (2014/35/EU) and documented CE marking.
- Advantage: The cable clears conformity assessment without re-engineering your panel or machine’s technical file.
- Benefit for your supply chain: Equipment exported to the EU moves through customs and site acceptance faster. You remove a recurring non-conformance risk flagged by third-party inspectors.
Built for Glass Plant Conditions
- Feature: Balanced construction that handles thermal cycling, abrasive glass dust, and occasional contact with hot surfaces.
- Advantage: Maintains circuit integrity even when ambient temperatures spike during a furnace run or a forming line jam.
- Benefit for procurement and engineering: One cable SKU covers multiple high-heat points — annealing lehrs, forehearth sensors, and melt level probes. You reduce inventory complexity while meeting plant safety demands.
Wholesale Logistics, Factory-Direct Lead Times
- Feature: Stock held in depth for glass factory profiles; cut-to-length and reeling on demand.
- Advantage: No artificial minimum order barriers or distributor markups on bulk runs.
- Benefit for your project: Scheduled, reliable deliveries aligned with furnace rebuild and cold repair windows. When you need 8,000 meters of 300°C cable by next shutdown, the volume is a conversation, not an exception.

Industry Applications & Scenario Validation
- Glass Container & Flat Glass Manufacturing: Connects thermocouples and pressurised sensors on furnace crowns, forehearth channels, and annealing lehrs where ambient radiation quickly degrades standard PVC or XLPE jackets. The 300°C rating matches the zone temperature without requiring active cooling of the cable run.
- Industrial Furnace & Kiln Builds: OEMs installing electric heating elements in ceramic or powder-metal sintering furnaces use this cable to reduce warranty claims. The insulation does not outgas aggressively, helping maintain a cleaner furnace atmosphere.
- Steel & Non-Ferrous Foundries: Used as extension links for ladle pre-heater sensors and continuous casting tundish monitoring. Resists splashed hot-metal spatter damage better than lower-temperature alternatives.
- Petrochemical Heater Trace & Refinery Hot Pipework: Delivers reliable performance on steam-traced lines and high-temperature flow meters where a sudden cable short can force a process safety shutdown.
- Plastics & Rubber Extrusion Machinery: Connects band heaters and nozzle thermocouples on compounding extruders. The cable’s high-temperature rating prevents stiffening and termination failure under frequent thermal cycling.
International Compliance & QA Standards
- ✅ CE Marking — conforms to the applicable EU directives (LVD 2014/35/EU, and electromagnetic compatibility where relevant)
- ✅ RoHS — meets restriction of hazardous substances requirements
- ✅ Factory production process aligned with ISO 9001 quality management system guidelines
- ✅ Routine production tests include continuity, high-voltage withstand, and insulation resistance at elevated temperature (reports available upon request)
- ✅ Packaging and labelling comply with international identifiers for traceability throughout the wholesale supply chain
FAQ
Q: Does the 300°C rating refer to short-term peak temperature or continuous use?
A: It refers to the continuous operating temperature of the conductor. The insulation system is rated to function at 300°C 24/7 without entering a thermal degradation window. If your application has occasional spikes above this value, please provide the profile to our engineering team — we can advise on a safe margin based on duty cycle.
Q: We run a glass furnace rebuild project. Can you supply the cable cut to exact lengths with labelled drum identifiers?
A: Yes. This is a standard request from maintenance planners during hot-repair campaigns. We supply cut-to-length cable on dedicated drums, with tags showing order number, cable type, temperature class, and metre count. This eliminates on-site cutting waste and speeds up installation.
Q: Is it possible to get a sample with a test certificate before we commit to a wholesale order?
A: Absolutely. Samples can be provided with a factory test report covering insulation resistance and a high-voltage test. We strongly recommend testing the cable in a mock-up of your racking or conduit configuration to confirm bend radius and termination compatibility before ordering in volume.
