The construction process of fire protection electric tracing tropical determines the late heat preservation with the effect of good or bad, fire pipeline is generally buried with the underground and the dark tunnel to go, if it is in the southern region, the external conditions are warmer, electric tracing tropical or can normal operation. Fear of the external temperature is very cold state, then the electric accompaniment heat to bear the voltage value is big, plus now the electric accompaniment heat equipment most manufacturers choose is self-limiting temperature model, when the temperature and self-limiting temperature gap is too big, resistance to change the minimum value will be easy to let the voltage device in the state of paralysis, this is the special place to pay attention to.
Then the fire electric accompaniment tropical construction process in order to the above phenomenon to occur in advance to electric accompaniment tropical each cable configuration a special thermostat, followed by if afraid of too much current, cable aging after the phenomenon of leakage plant can also be considered in the pipeline next to the installation of anti-leakage switch. After installing the thermostat, after setting the temperature to the rated value, put it at the mouth of the wall of the electric accompanying heat pipe that can feel the temperature, so that the thermostat can effectively control the work of the heat dissipation of the whole pipe, also convenient after if the electric accompanying heat pipe which stage has a problem, can see directly through the temperature control switch indicator which section of the electric heat tape has a problem directly can be replaced.
To make direct contact between the heating cable and the pipe of the fire protection electric heating cable, and to distribute more heat, you can consider using aluminum foil tape to bond the two pipes, which can protect the cable, but do not let the two cables in a suspended state, which is prone to accidents.
