The electric heating cable is has the explosion-proof, takes the explosion-proof grade, the ordinary explosion-proof product for the mandatory authentication, therefore must have the production permit certificate and the explosion-proof certificate of conformity can feel that the product belongs to the explosion-proof product. When the demand for explosion-proof area installation of electric heating cable, should also pay attention to the electric heating cable need to meet the explosion-proof specification can be applied.

                           Ordinary incineration and explosion of the three factors oxidizer, combustible material, ignition source, as long as there is a factor does not exist, there is no incineration or explosion phenomenon. Electrical hetaing cable itself disaster normal operation conditions, will not produce explosive mixture of sparks or menacing temperature.

                       The electric heating cable in the layout of the metal shield layer, can realize the grounding function, prevent the abnormal operation (common is the outer sheath waterproof not pass damp probably site construction is not standardized) fire phenomenon. And through the explosion-proof junction box can be guaranteed to heating cable discussion at the close continuation and safety grounding. This is similar to the explosion-proof area, the power line outside the explosion-proof hose to increase the safety factor is the same thing.

                          Electric heating cable can be self-regulating, electric heating cable power is mainly controlled by the heat transfer process, with the temperature of the heated system automatically adjusts the output power, and the traditional constant power heater but no such function.Heating cable because of the safety and reliability, energy saving and environmental protection, heat uniformity, easy installation and maintenance, long service life and other characteristics, has been widely used in various fields.
