TCWDuplex Insulated Thermocouple Wire

Duplex Insulated Silica-glass-yarn Braided Thermocouple Wire

Max. operating temp:400℃
*Resistant to short-term overheating

We provide flat duplex insulated high-heat-resistance thermocouple wire consisting of a pair of conductors individually silica-glass-yarn insulated, silica-glass-yarn sheathed, and then covered with a (dark brown) polyimide coating. With excellent heat resistance and electrical insulating properties, they maintain excellent flexibility without degrading their strength even at temperatures close to the normal-use temperature limit.
