K type compensation conductor
Description
Application: Compensation wire cable series products are suitable for the temperature control system of energy, metallurgy, petroleum, chemical and other factories and mining enterprises and scientific research departments. It is used for the connection between the cold end of the temperature measuring instrument and the temperature measuring instrument. Heat resistant type uses fluorine plastic insulation and sheath with excellent heat resistance, water resistance, corrosion resistance, acid and alkali resistance, chemical resistance, wear resistance, aging resistance and non-combustion performance. Implementation standard of compensation cable: GB/T4989/94 equivalent IEC584.3
