The DJR-760 ceramic electric heating band is suitable for AC 220V or 380V power supply, and the rated power can be configured in the range of 1.5kW to 4.5kW according to the installation dimensions. The product housing can be made of stainless steel or galvanized sheet; when purchasing, the corresponding material should be selected according to the corrosiveness of the workshop environment and the risk of mechanical impact. The terminal block has a ceramic insulation structure and a temperature resistance rating of 450°C.
Common inner diameter specifications cover φ60mm to φ400mm, width 20mm to 100mm, and the standard lead length is 300mm, which can also be adjusted according to the wiring distance. Purchasing personnel should check the outer diameter, width, and lead outlet direction of the equipment's heating zone to ensure that the clamp or bolt fixing method is consistent with the original installation position.
When the heating band does not work or the temperature is abnormal, first observe whether the body has cracks, deformation, or burn marks, then check whether the terminals are loose, oxidized and blackened, or rusted stuck. In case of frequent burnout, check the insulation condition, power supply voltage stability, heat dissipation conditions, and whether it is in contact with corrosive media. The maintenance records should retain the appearance and wiring status at each replacement for traceability.
This model is commonly used in heating parts such as injection molding machine barrels, extruder screws, pipeline heat tracing, and small ovens, and is suitable for working conditions requiring ceramic insulation and relatively high surface temperature resistance.
