This invention relates to the technical field of low-smoke halogen-free flexible busbar products, and discloses a low-smoke halogen-free flexible busbar including a busbar and an insulating sleeve. This low-smoke halogen-free flexible busbar utilizes a movable component. When a damaged insulating sleeve needs to be replaced, a sliding plate is operated to slide within a retaining sleeve. The sliding plate drives the insertion shaft to move, and the insertion shaft inserts into the interior of a limiting block. When the insertion shaft moves to a groove in the limiting block, a telescopic rod inside the movable shaft resets under the action of a fixed spring, causing the insertion rod to reset and be fixed inside the limiting block. This creates conditions for subsequent installation of a new insulating sleeve. When the insulating sleeve is damaged, it can be quickly replaced and re-fixed, preventing air, moisture, or dust from entering the busbar surface, avoiding problems such as reduced insulation resistance and partial discharge caused by external media corrosion, extending service life and improving replacement efficiency.
