We can supply several types of compensating cable, e.g. extension wire,normal type cable, rubber covered cable, heat resistant cable, shielding cable.
a. The dimension of the compensating extension wire is 0.4*1.0mm, this wire is used for making the expendable thermocouple tip.
b. The rubber covered compensating cable is used for connecting the lance with indicator, the cross section area is 1.0 mm2, the outer diameter is 5.1*8.0mm;
c. The heat resistant compensating cable is used inside the lance, the cross section area is 1.0 mm2,the outer diameter is 3.1*5.6mm.
