Laying the heat tracing cable in the pipe can avoid affecting the operation of the pipe network because of the pipe freezing. The size and structure of the pipe for laying the heat-tracing cable is exactly the same as that of the ordinary heat preservation pipe. The outer wall of the special heat-tracing cable scarf steel pipe is laid in parallel with it, and the point heat is used to heat the medium through the steel pipe. The heating power Z of the cable is large at the moment of just electrification, and the resistance of the PTC memory material in the cable increases gradually with the increase of temperature, so the working current and electrothermal power also gradually decrease, until the heat loss of the heating power compensation system makes the temperature of the system in a stable state. When the ambient temperature decreases, the cable power increases automatically and the loss is compensated automatically, so that the system is in balance at the new temperature. This compensation heating method is *.
