Description

Technical Field

[0001] The utility model relates to the technical field of cable heating, in particular to an online cable heater. Background Art

[0002] Wires and cables are widely used in various industries. For example, household appliances require electrical wiring for power. Typically, wires consist of two parts: a plastic sheath surrounding a copper or aluminum core, and an outer sheath protecting the core from mechanical damage. Wires and cables are manufactured through three processes: drawing, twisting, and sheathing. The more complex the model, the higher the repeatability. After sheathing, the cable needs to be heated to ensure adhesion between the PET tape and the copper foil. The previous method of heating the entire cable reel in an oven resulted in uneven heating inside and outside, and prolonged baking times. This resulted in incomplete adhesion between the PET tape and the copper-plastic foil during processing, resulting in defective products.
