High Temperature Cable for Ovens
High temperature cable for ovens is a purpose-specified multi-core silicone rubber cable for the power supply and control wiring of industrial baking ovens, commercial cooking equipment, food processing ovens, and laboratory drying ovens — applications where the cable must withstand continuous contact with oven enclosure surfaces at temperatures that would cause standard PVC-sheathed cable to soften, harden, and fail within months of installation.
The cable combines individually silicone-insulated cores with a silicone rubber outer sheath, providing a two-layer protection system that maintains electrical integrity and mechanical flexibility from –60°C to 200°C continuously. At oven ambient temperatures between 150°C and 180°C — typical at the cable entry gland on an industrial continuous oven — the silicone rubber sheath remains completely flexible, undegraded, and free from cracking or surface charring, while standard PVC would be well beyond its 70°C continuous rating and actively degrading.
Core insulation is produced under UL AWM Style 3135 (200°C, 600V AC) under UL Follow-Up Service File No. E333030, providing verified insulation performance for projects requiring UL-recognised components.

Common Applications
Industrial baking and food processing ovens
Industrial continuous tunnel ovens, rack ovens, and deck ovens used in bread, biscuit, and confectionery production require a cable that can withstand decades of continuous service at oven enclosure temperatures between 120°C and 180°C while supplying both the heating element power circuits and the temperature sensor and control signal circuits. The multi-core silicone cable provides live, neutral, earth, and signal cores in a single cable through the oven entry gland, minimising the number of gland penetrations required.
Commercial kitchen equipment
Used as the supply and control cable for commercial combination ovens, combi-steamers, rack ovens, and heated holding cabinets in restaurant, hotel, and institutional catering operations where the cable must survive the demanding combination of high ambient temperature, steam, cleaning chemical exposure, and the mechanical stresses of equipment movement on castors.
Paint and coating cure ovens
Industrial paint cure ovens operating at 150°C to 200°C require high temperature cable for the power supply to heating elements and the wiring of temperature controllers, fans, and conveyor drive systems inside the oven enclosure. The silicone cable withstands the paint solvent vapour atmosphere without degradation — an environment that accelerates PVC deterioration significantly.
Other applications
- Laboratory and pharmaceutical drying and sterilisation ovens
- Textile drying and finishing equipment
- Powder coating cure ovens
- Ceramic and glass annealing ovens (wiring zone only)
- PCB reflow and wave soldering oven wiring
