Thermocouple Cable

OHMALLOY cable factory have 30 years in producing the thermocouple extension or compensation cable. We use our own thermocouple conductor to produce all kinds of insulated thermocouple wire and cable, Resistance Temperature Detector (RTD) cables. Working temperature range is -60℃ to +1100℃. According to customer request, we supply professional wire and cable solution.

Now OHMALLOY have all processing matching for braiding, extruding, wrapping, varnishing....  So we can make all cable with all insulation such as PVC, PTFE, Silicone rubber, fiberglass,

The MOQ for fiberglass insulated wire can be any length, even 5meters is ok.

For the insulation such as PVC, TEFLON, we can supply 500meters as MOQ. That can help many customers on trial stage.
