Compensating Wire and Cable for Thermocouples

1.Application

It is manufactured according to the standards of GB/T4989—1994 "Compensating Wire for Thermocouples" and JB/T7495—1994 "Compensating Cable for Thermocouples"

椀琀 is mainly used as the connect wire in the automatic measure instruments in the electronic power industry, chemical industry, petroleum industry, metallurgy industry and national defense industry, etc.
General PVC insulation and jacket compensation wire or cable with excellent moisture-resistant, wear-resistant and fire-retardant properties; fluoroplastic high temperature insulation and jacket compensation wire or cable is used by continuous extrusion process with resistance high temperature, resistance cold , resistance acid and basic ,resistance water, extension of combustion , anti-aging superiority, properties ,the quality of products is?? higher than international requirements GB GB/T4989-94 (equivalent using IEC584-3).

2.Operating Characteristics

The working temperature of the common compensating lead and compensating cable is -20℃~+100℃, and for the high-temperature resistant compensating lead and compensating cable, the working temperature is -25℃~+200℃.
Compensating wire and cable for thermocouple is permitted bending radius:
The minimum bend radius of the compensating lead should not be less than 6 times of the cable's actual external diameter; for the compensating cable, not less than 12 times of the cable's actual external diameter.
Compensating wire and cable for thermocouple lowest environment temperature:
Common compensating wire and cable for thermocouple: Fixed deployment -40℃, Non-fixed deployment -15℃.
Compensating wire and cable for thermocouple with heat : Fixed deployment -60℃, Non-fixed deployment -15℃.
