AI Technical Summary
Technical Problem
Traditional methods for de-icing overhead cables are inefficient, ineffective at removing thick ice build-up, and can easily damage the cables.
Method used
The sheathed explosive shock wave cable de-icing device utilizes the heat and shock wave generated by the sealed detonation cavity between the inner and outer sheaths. This heat and shock wave are then broken through the ice-breaking sealing plug, allowing the ice fragments to fall directly and avoiding direct damage to the cable.
Benefits of technology
It achieves efficient removal of thick ice glaze, protects cables from damage, and reduces the damage caused by ice glaze to the lines.
