How It Works / Is Used

High temperature cable is used to connect electric heating elements to power supplies or temperature controllers in environments where elevated temperatures would damage standard electrical wiring. Silicone cable insulation retains flexibility and dielectric strength even when installed close to heater terminals, hot surfaces, or heated enclosures, ensuring safe electrical performance under thermal stress.

Heater cable is typically installed during heater manufacture, equipment assembly, or maintenance replacement where existing leads have degraded from heat exposure. Correct cable selection ensures electrical integrity, prevents insulation failure, and supports consistent heater operation in industrial heating systems operating at sustained temperatures.

Ideal Uses & Applications

Heater cable and silicone high temperature cable are widely used across UK industries where electric heaters operate in elevated-temperature environments, including:

  • Cartridge and band heater connections
  • Flexible heater mats and jackets
  • Industrial ovens and furnaces
  • Process heating equipment
  • Packaging and sealing machinery
  • Plastics and composites processing
  • Laboratory heating systems
  • OEM heater and equipment manufacture

They are ideal wherever electrical wiring must remain safe, flexible, and reliable in close proximity to heating elements or hot process zones.

Important Considerations & Safety Notes

  • Always select heater cable rated above the maximum operating temperature
  • Ensure voltage and current capacity match the heater electrical load
  • Avoid mechanical strain or sharp bending near heater terminations
  • Protect cable from abrasion or contact with sharp metal edges
  • Maintain insulation clearance from direct radiant heat where possible
  • Replace heat-damaged or brittle wiring immediately
  • Install and terminate by qualified electrical personnel
  • Follow UK electrical and equipment safety standards

Frequently Asked Questions (FAQs)

What makes cable suitable for high-temperature heater applications?

High temperature cable uses heat-resistant insulation, typically silicone, which maintains flexibility, dielectric strength, and mechanical integrity when exposed to sustained elevated temperatures near heating elements.

Can silicone cable be used with industrial heaters?

Yes. Silicone-insulated cable is widely used for industrial heaters because it withstands continuous heat exposure and remains flexible for routing within heater assemblies and equipment.

How do I choose the correct cable?

Selection depends on operating temperature, electrical load, voltage rating, insulation type, conductor size, and installation environment relative to the heater or heated surface.

When should heater cable be replaced?

Replacement is recommended if insulation becomes brittle, cracked, discoloured, or electrically degraded due to prolonged heat exposure or mechanical stress near heater connections.

Is high temperature cable required for all heater installations?

It is required wherever wiring is exposed to temperatures exceeding the rating of standard PVC cable, particularly near heater terminals, hot enclosures, or high-temperature process zones.
