(7) Insulation resistance: The insulation resistance between the electric heating conductor and the metal shield should not be less than 500 MΩ.

Advantages:

(1) Automatically adjust the output power and compensate according to the actual heat required by the heat tracing system, which is a new generation of energy-saving constant temperature heater.

(2) It can be arbitrarily shortened or extended within a certain range, and it can be overlapped multiple times without the concern of high temperature hot spots and burnout.

(3) Low temperature, fast start, uniform temperature, because each part can be automatically adjusted due to the temperature change of the heat-tracing place.

(4) Easy installation, simple maintenance, all-day service, high level of automation, and low operating and maintenance costs.

(5) It is safe and reliable, widely used, no pollution to the environment, long service life.

(6) The maximum allowable length of circuit breaker for medium temperature series "C" type.

Nominal Power Output Rating on Metal Pipes at 220V

Application:

The low temperature self-regulating electric heating series is widely used in the heating, anti-coagulation and anti-freezing of pipelines and storage tanks of civil solar energy, geothermal heating, fire protection, petroleum, chemical, steel, electric power and environmental protection industries. The electric heating cable is suitable for general areas, hazardous areas and corroded areas. Using with the explosion-proof power supply junction box, it is suitable for division 1, 2 and explosive mixture gas "T4-T6" group of the factory that are not directly impacted by external forces.
