What are the resistance parameters of the nominal resistance and insulation resistance of the heating cable before and after dark laying in the floor radiant heating system?
The nominal resistance of heating varies according to different models of each brand.
For example, the heating resistance value of German Manpai heating cable ATHC-2680 is 18.08 ohms; ATHC-680 cable, heating resistance: 70.97 ohms.
It is suggested that the insulation resistance should be as high as 100 megohm.
