Compensation wire, Compensation cable

Executive standard: Standard GB/T4989-94 or equivalent IEC584-3
Features and Applications: Compensation wires and cable are used to extend the cold ends of the thermocouples in the temperature-testing systems. The cable uses imported teflon as insulation and sheath and is produced by advanced extrusion machine on the assembly line. It has good resistance to high and low temperature, acid, corrosiion, aging, as well as oil and water. Working temperature is -40～275℃
