The hot water medium in the reaction kettle at low temperatures can affect the execution of the entire process. In view of the temperature demand of hot water pipeline, it is recommended to use parallel type constant power electric heating cable tape. The electric accompanies the tropical heating temperature high, the temperature resistance is high, the heating temperature can reach 120-150 degrees or so, the use temperature controller can maintain the medium temperature in 60 degrees or so.

                                 In order to prevent the reaction kettle hot water heat loss temperature reduction, process production needs to maintain the hot water temperature at about 60 degrees. So use the electric heating cable preservation system, installs the accompanies the tropical strip to wind in the reaction kettle the surface. The electric accompanies the heat of the heat tape energized, compensates the heat loss of the reaction kettle, maintains the temperature above the demanded temperature.

                The reaction kettle uses the parallel constant power electric heating cable heat core for two parallel insulated copper wires, then in the insulating layer winds the electric heat wire, the electric heat tracing cable wire connects with the busbar every certain distance, forms the continuous parallel resistance. The electric heating cable wire connects with the busbar every certain distance to form a continuous parallel resistance. After the electric heating tape is energized, the parallel resistance heats up, thus forming a continuous heating of the electric heating tape.

　　         Reaction kettle electric heat cable tape unit power is constant, heat is constant. The longer the use of electric heat tape, the greater the total output power, constant power electric accompanying tropical installation can be in accordance with the actual length of any cut, but the shortest shall not be less than 1 heat node, generally at least 3 meters long.

                        Reaction kettle electric heating cable tape is soft and good, can be conveniently laid close to the surface of the reaction kettle. And accompanies the tropical layer has the shielding braid layer, has the grounding and the protection function, also has the heat transfer and the heat dissipation function. In addition, the protective outer sheath of the electric accompanying heat can improve the overall tensile strength of the electric accompanying heat.
