Single Pair Thermocouple Cables

Fibreglass Insulated Flat Twin

  • Excellent for high temperature applications up to 480°C for Fibreglass, 800°C for High Temperature Fibreglass and 1400°C for Ceramic Fibre
  • Suitable for use at normal air ambient temperatures where there is a possibility of a hot spot which might damage lower rated cables such as PVC or PFA
  • We offer a wide variety of constructions from simple lapped and Fibreglass braided to stainless steel braided types in virtually all the thermocouple combinations
Fibreglass Flat Twin 
One pair of solid conductors. Cores double glass fibre lapped, braided and silicone varnished. Pair laid flat, glass fibre braided overall and silicone varnished.
